- Hello Radio Operators.
in today's video, we will be answering many of the questions you all have asked about my #RaspberryPi.
The Raspberry Pi software and mods in the videos are running on Yaesu FT-891 and Yaesu FT-817 HF radios, but the RPi could work just as well with an Icom or Kenwood ham radios as well.
About the only thing I am not doing with the Raspberry Pi for ham radio is using it for Echolink, because Echolink is not ham radio Hi Hi.

Great work Julian, love your ideas and experiments!
Omg you give me so much to think about I don’t even know where to start. Love your voice and your channel.
Great video, as always. I am glad to know there are hams out there that agree with me about amateur radios and computers being a perfect match. Manufacturers have, for too long, sat back and distanced themselves from computers so as not to become just a computer add-on.
WOW! I have been trying to figure out how to work my Pi into my Portable ham radio system. I never thought to run it headless!! WHAT A GREAT IDEA!! That will fix most of what I was trying to figure out. I am just getting started in digital modes and learning a lot. Thx for the Video!
Awesome video, thanks for sharing your knowledge, I'm going to get started with integrating a rasp pi into my radio setup soon.
Julian, thanks for all your efforts on designing and building this station. We all have lots to learn from you. Keep up the good work.
I'm not worthy 😀
If I could contribute just half of what you've contributed to ham radio, I would be proud of myself.
Thanks for the kindness and inspiration. It's always appreciated.👍👍👍

Thanks for the compilation of tech Julian. There are a few of us down here in VK3 that are setting up Pi's for /p operation on HF. 73's
You are very welcome Darren. So many ways to approach this, that I don't think anyone way is right or wrong. It's just awesome having the ability to put something together as an integrated kit. Looking forward to seeing some of those Raspberry Pi setups from down under.

Ordered the components shown in your video, the interoperability is what I'm looking for also, very impressive as always
Your comments absolutely made my day Philip 👍👍👍
Another great video! You are definitely on the right track and we all owe you a big thank you!
Looking forward to your video where you show how the Raspberry PI incorporates CAT control for your two radios and how it integrates with the other software.
Thanks John. I think I can make a short video on cat control for the 891 and the 817 on Raspberry Pi. 891 support is pretty bad in FLDIGI, but wsjt-x and FT8CALL are perfect.
I'm glad you like the direction. If I can figure out an enclosure for the audio interface and Raspberry Pi, this project will become a lot more practical.

This was a really good video! I just started using a Raspberry Pi with AMBEserver and a ThumbDV dongle, and it really supplies some wonderful features. I hadn't thought about marrying it to my field rig in this fashion, but there's no reason I can't. I've got a perfectly good KX3, and putting the programs you use on a Pi like that is utterly fascinating. I'm going to explore that further, and take a look at some of the Pi related gear you've mentioned. There are a couple of Pi UPS options, including some on Tindie and I think on Crowd Supply as well. One of them might serve, but I like the idea of the RTC your hat provides.
Thanks again for such a good resource!

Great job as always. I'm working along with a setup with my 817. Always enjoy your vids and instructions. 73 KF7VUT
Thanks Tim. I'm also doing the 817 but out of public view. What's the goal of your 817 project?
Thanks Julian great video. i agree why not just have an open interface/sound card built into rigs then you could choose what mode to be using. PSK31 was good but that's not where the action is today in 2019. My ic 7200 is a good rig for digital modes and easy to interface to a laptop but its too big to be carting too far in a back pack not to mention the battery needed to run it .
I entirely agree with the point you've made regarding the possible inclusion of single board computers in new radios. As propagation continues to decline and is likely to stay low for some years to come digital modes and low power operations will come into higher usage. Having rigs which support digital operations just makes sense. The first company to add a single board computers to any rig will likely gain market share and set the bar for others to follow.
Thank You Marvin
What a wonderful video. Thank You! 73

Well, it's skilled operators like you that help those like me to perfect our skills.
As you requested, my Own PiProject: One of my many Pi3 serves as a portable APRS Station running direwolf. I can connect via APRS Droid or APRSIS32 or any other software via KISS or AGWPE Port. I have a wide range voltage regulator and an old Albrecht hand TRX for 2M in a Box, so as long as I have a 12V Source (such as my SLAB or LiFePo4) I have a WiFi Network and APRS.

thanks for making this vid, I've been wondering how well the Pi could handle other applications besides the SDR software
You are very welcome. The Raspberry Pi does a great job with data modes for amateur radio. Honestly I wouldn't have believed it yeah, but the Raspberry Pi 3 B+ does a great job. Thanks for the comment and the kindness, It's very much appreciated.
Awesome
Julian you have shared wonderfully detailed information on building a solar generator for operating off grid. One vita vital piece of man portable equipment is a VHF/UHF HT. It would be great to see you cover charging HTs without access to the grid or an inverter. Many of us are using the FT-70DR or similar and I have not found a way to charge this radio via a solar panel. Thoughts?
I was going to do something similar, but I was able to get the FT8Call program to run successfully on my Chromebook using the crossover app.
Since the RasPi does not have a real-time clock that is persistent. I have used the "DS3231 Real Time Clock Module 3.3V/5V with battery For Raspberry Pi and Arduino by Atomic Market" as a real-time clock between power shutdowns on a few projects - works great. - I like the GPS idea too. Thanks for the video.
Excellent feedback. I have another Raspberry Pi here for the 817, and I wondered if I was going to use the pie juice for that. Perhaps I'll try it your way on the other Raspberry Pi.
Thanks for the comment and sharing your project. That's extremely awesome!

Great video. Thanks for pulling it all together. I have just started working with the Raspberry Pi and FT-8. Using my TS-590 with the Pi. When setting the output power on the TS-590 at 30 watts...the output power meter only shows 15 watts when FT-8 is "sending". I suspect that the audio output from the Pi isn't as robust as it potentially could be. Would you have any idea what may need to be modified on the Pi to boost the audio output? Thanks again for a video with solid information.
Really liked this UA-cam as it describes exactly what I wanted to do with my rig's IC7300, KX2, FT897, and others. So thank you for the very clear information on this and others that I have watched. Question is there a hard listing of what you have done on your site please? --- Just seen the link below so I will go there first. ZL1MX
Hello Martin. Have a look at this link on my website: oh8stn.org/off-grid-raspberry-pi/

Good video - what cat cable did you use ?
You are spot on with your point about Mfrs just not getting todays requirement. An innovative new entrant would make a 20W radio (with a small onboard LIPO battery and a separable larger external LIPO clip on blister pack) that is simply a black box with an antenna socket, on/off switch, audio/mic/data/network ports, embedded GPS , ATU, wifi & Bluetooth built in. Basically no onboard displays, buttons or dials - should put reliability up and mfr cost down. If the CAT control commands were robust and extensive (and open source) and the Bluetooth/wifi suitably thought through then let Android developers come into the marketplace independently to produce the Android software variants required by the community for JT8Cal/Winlink/selcall/ALE etc. The vision would to be have all functionality operated through any android device untethered to the box - even remote from it.
Only in my wildest dreams. That would be an amazing radio. In fact I would just settle for the Black Box radio with cat control, internal battery, built in audio codec, and selectable filter width.
I've been dreaming about this Radio 4m about 10 years of the best we seem to get this stupid manufacturers putting psk31 in their transceiver.
I don't think any of the display interfaces I've seen you use are tough enough or good enough tbh. I've decided I might as well use a Chromebook with ARM processor. I don't care at all about remote operation of the radio. I hate VNC too it just irritates me. I don't see why the software even needs a GUI at all to be honest. I'd love to use a Pi if I could get away with a 16 segment display and rotary encoder for a keyboard and make the package tough as nails. Thanks for your work it's really inspiring.
UPDATE: Chromebook is not go with GPS dongle :( There may be generic access to USB via Crostini in the future.
Wow, these videos make me imagine a lot of possibilities! As far as HAM radios with an embedded Raspberry Pi; I'm envisioning Xiegu (or Baofeng) releasing an HF/VHF/UHF rig, that also houses a Raspberry Pi, complete with a 20Ah battery, and compact solar panel, all for $199.00. *lol*
Sounds like an awesome idea but I wouldn't hold my breath. I'm about to publish a new video on this topic so stay tuned
@@OH8STN I'll definitely be here!
Excellent video, thanks for sharing. Might try using the Pi rather than Window 7 mini-laptop.

I tried to make it as non-geek as possible. Besides Communications in a grid down scenario is important for anyone not just technically inclined. Thanks for the comment, and stopping by. It's very much appreciated
U did a good job, not being familiar w this jargon, I understood the concepts :) now if son in law THE geek, can set me up w one lol what s an average cost for such a set up?
Dear Julian, thank you for your excellent videos and detailed help. You give us and amateur radio a new and valuable inspiration.
I tried to rebuild your setup: FT891, Raspberry Pi 4, MiniPro SC... Unfortunately I can't decode JS8Call signals... Which settings do you make in Raspian OS and which sound card did you choose?
I've watched all your videos several times and also almost all documentation about JS8Call... Unfortunately I can't find any help for my problem.
Thank you in advance.
vy 73 de Oli, DL2OLI
Hi Oliver. My station set up is different at the moment, so getting those settings isn't possible at themoment. Make sure you have enabled the audio interface in your USB audio settings. You can reach those audio settings by right clicking on the speaker icon on your rpi desktop. Here's a few other tips for you.
Make sure you're using the correct port on your radios settings. Make certain you have selected the correct audio device in js8call. If you can see them in the waterfall but cannot decode but see them in the wsterfall, make sure your clock is accurate on your Raspberry Pi.
hi , love the video. do you also run a logging software on your pi? i'm uising cqrlog at the moment but seeems it doesn't want to do radio control on the ic706 i use
Not at the moment, but I just saw this blog post from my buddy Mark explaining how to do it. m0iax.com/2018/11/02/integrate-logging-software-to-js8call/
So I got my license about two months ago, I've been playing with a little baofeng just to learn and make contacts. I just bought a raspberry pi 3 b+ and looking to start a build similar to yours. What was your steps to get your pie hooked to your Android. The steps you showed in the video is not in-depth in others that unfortunately i get a little lost on and afraid to try and have to reformat my SD card.
I'm a little confused, as I often am. Looking at your blog entry for the headless rpi setup, are you saying that the tutorial linked allows the pi to switch between being a hotspot and connecting normally with your home wifi ? Or is there some other script required? As I understand things the tutorial is permanently creating a hotspot using wlan0 and would thus preclude linking to standard wifi when available. This is a great video and has inspired me to try setting up my own headless pi for use with my ft-817.
Edit: Sorry I didn't open the "read more" to see the rest of your question. So what you're saying is basically correct. There is that other script but let's ignore that for now. The way things run now my Raspberry Pi always creates that portable Ops Network. But you see that home network entry in the VNC when I plug in an additional Wi-Fi adapter it will connect to my home network giving the Raspberry Pi access to the internet. And now if we talked about that other script there's a way to do it so that the Raspberry Pi will connect to a local Wi-Fi network if it finds one. If it doesn't find one it'll create one of its own to allow you to connect remotely to it. That's the link the other operator shared on my Facebook page. I'll have to find that and update the Articles or perhaps make a brand new episode notes specifically for this video. Hopefully you can share your results with us. When we have these type of discussions it creates good searchable information for Newcomer's trying to achieve the same goals.
Thanks for the comment and pushing me forward. It's very much appreciated.

I agree that the manufacturers are not paying attention to our
desires..
Great video, just got my first hf rig FT-891. Now I trying to understand all the components needed for digital communications. So instead of using a Signallink you us a ZLP Electronics MiniProSC.
Is the Signalink old technology compared to the MiniProSC?
Hi Gerry
The SignaLink USB is fine. I use the ZLP because it's smaller, and only needs a cable change to configure for a second radio. No internal jumpers pucks needed. The Signalink has the added benefit of front panel level control. If you like to fiddle, the Signalink is good. If you want to configure and forget, the ZLP.
Hope this helps.

Thanks for great videos! I have an samsung tablet and a wolphilink I was using for PSK ... I have seen some people who have placed a full linux distro on their tablets. This would let me use the FT8Call (in theory at least). Do you think the wolphilink via the headphonejack would work or is it missing the soundcard aspect of this system?
Great question.
My friend VA3ISO uses this configuration. Android Tablet Wolphilink, JS8Call. The sound card is built into the tablet, so the Wolphilink works as PTT and interface. So go ahead and give it a try. Wouldn't hurt, it might actually be a pretty awesome set up.
Hi Jilian was curious what the other box was in the video then figured it out DigiMaster MiniProSC. Can you tell me why you chose that over the more popular signal link usb sound card? Maybe do a video on it???? Thanks so much. Love your videos.
Hi Mike. The signalink is simply massive. Since I do so much portable Ops, I wanted something that was smaller. I also didn't want to change out jumpers every time I switched radios. Nothing wrong with the Signalink, it just wasn't right for me.
I think I've done several videos on this audio interface already. They may be outdated though.
Thanks for the question and the kindness. It's very much appreciated.
thanks so much must have missed them will go back and check and thanks for the fast response :)

Julian Many Great Viedos. However the cabeling between the radio and the Rpi escapes me. The radio has a Din data port right. I use a 706 which has 12 pin Din data port. Did you buy a din x usb cable? No signal link or equal is needed? Thanks John
In this video there's two cables between the Raspberry Pi and the radio. The first cable goes between the Raspberry Pi USB via the audio interface and into the mini din Port of the radio. II cable also originates from the Raspberry Pi USB and terminates in the USB port of the radio. That one is for cat control.
I have Direwolf, and Pat IO set up. I just can't seem to get the ax25 /dev/tty/USB0 To Kiss Attach. I followed the script info Pat.Io to start the service..
The audio interface seems like a significant contributor to operational complexity. Do any of the smaller HF rigs allow direct connection by USB for RX/TX of audio and cat control?
From small portable rigs, just one, the mcHF. It has a single wire interface for audio and CAT control. Yaesu and Icon as well, but not in a portable package.
For the 891 CAT control is one sub cable. It's the audio interface which adds size and complexity.
Great question!
The IC-7100 has a USB connector that I use for CAT control, albeit with W10 and HRD. I'm getting my RPi 3 B+ all together to do the job when portable at the moment. de VA3NIE
Every amateur and commercial radio has bugs or issues. Best we can do is have intelligently select the best option for our requirements.
Hi, not sure if you heard about Digipi recently published. Would the FT891 work? Thank you for sharing.
I have heard about it. It's just another gimmick. Hopefully it's an easier to configure gimmick . It would definitely work with the ft-891 however.
I am looking to buy your Raspberry Pi setup. One question. The keyboard you have is red which links to the wireless one, not the Bluetooth one. Can you confirm if I should purchase the Bluetooth or the wireless version to connect to the pi?
Yes it's the Bluetooth one Dennis. When I purchased it there was a choice in the drop-down box for the different versions. But it's definitely the Bluetooth version. Thanks for the question
ft8call, so i do not see a mode in TQSL for QSO use in that mode...wonder if it will become a valid mode like psk*
Julian, what is the model number of the flex solar panel? It looks like what I need. Wattage? de ke4rk
PowerFilm FM16-7200. If you're at lower latitudes you can get by with lower wattage.
Does this kit (CanaKit - Raspberry Pi 4 Starter PRO Kit 4GB RAM) have enough to utilize ham applications using Debian or Ubuntu? I appreciate any guidance and help you can offer.
Excellent, Julian! I'm just wondering, do you think it would ever be practical or necessary to have a separate waterfall display for reception in the field? I might be able to see the practicality in some sort of SHTF or other ermcomms scenario (depending on its severity) if we're trying to easily determine who's out there trying to communicate. Just a thought, but I'd love to know your thoughts on this.
Btw, I feel truly fortunate that we, the international ham radio community, get to benefit greatly from all your very practical experiments in the field. It's one thing to theorize about all this stuff, but quite another to field-test all of one's choices, make any necessary adjustments, etc. I'm so grateful to you for what you do. 73, k1rsk
I'm kind of taken aback by your kindness, and don't really know how to respond. I guess I'll just say thank you.
Regarding your question, it may not be completely obvious but in fact I may minimalist. That's even more true when I'm operating on foot. I've seen the external waterfall displays on kx3 kx2 and so on, but since my rig has a spectrum analyzer built in, I don't think I would take the extra weight, loss of payload, an additional current drain of adding such a device. That perspective might not be correct for everyone. I see operators carrying external water meters, external SWR meters and all kinds of crazy things to field day. That stuff is all pretty cool for the shack but in the field it's just another level of complexity preventing us from portability and a more rapid deployment. On the flip side, if it has some utilitarian function, I'm all for it.
That makes a lot of sense, thanks! Btw, I recently did purchase an FT-891 based on your and W5KV's experiences with the radio. I'm in the process of erecting antennas now and planning my portable setup, but I'm very much looking forward to great fun and many adventures with it! 73
There's a couple of silly things with the radio that you can definitely get used to. On the glip side, you'll have zero regrets buying that radio. It's got the best receiver of any radio I've ever used. Anyway, you are very welcome. I hope you share some of your upcoming Adventures on UA-cam.

Thank you, Julian, you certainly have inspired me to want to share! 73, robert
SBC's and arduino are the future of ham radio. I can see a day when sbc's have a hat for each part of the qrp. Like transmitters and receivers did years ago. Integrating SBC's in to radios will only increase the price of an already expensive hobby.
Although I can almost completely agree with what you said, I'm dealing with ham radio in todays world, with the equipment I have available now. It would be pretty awesome living long enough, to see the future you envision 👍
How do you supply the 5 volts from the buck converter to the Pi? Do you use the GPIO pins or did you solder leads directly to the board? If you soldered to the board what pads did you use? Was it P2 for + and P5 for GND?
I used gpio pins 👍
@@OH8STN 😊! Thanks!
Hi Julian, I have built something very similar to work with my FT-817 and FT-897 - I have the same Zlp Interface - however I am having problems getting cat control to work do you have any tips? I also added Pat - the winlink client to my Raspberry Pi, and used cgps from the cmd line to get the maidenhead locator from the GPS
The only time I've had problems with cat control on the eight one seven or eight one eight is when I've used one of the Chinese cat control to USB adapters. I didn't have any problems with the ZLP version. I would say most of the time, it's the cat control adapter which isn't supported.
love the content. WP4QCR🇵🇷😎
have you any software u use for voice log? or only digimodes on the station?
I use an android app for logging called Hall of. It also works on IOS.
Hi Julian,
could you please share your experience with Pi cooling? The processor is relatively hot. Do you use any additional heatsinks, coolers? What is the average CPU temp while using JS8CALL?
This is an excellent topic to add to my Raspberry Pi for ham radio FAQ.
We must always add heat sinks to the Raspberry Pi. They're not included a standard, and most people who use a Raspberry Pi for a media center or something like that probably don't even need them. Running digital modes, decoding those incoming signals is very cpu-intensive, so heat sinks are mandatory for our ham radio applications.
Some operators choose cases with built-in fans, those are fine if they don't make noise. Still there meant to be used along with heat sinks. I'm not using any fan. I simply use good heat sinks and thermal paste. I hope this helps.
73
Julian oh8stn
Thanks.
BTW yesterday I tried to relay a message to you via VK2RT. We had very good propagation between us and his station reported hearing you at -17.
Unfortunately band conditions got worse suddenly. Maybe next time.
Hi Julian none Pi comment, you utilities DigiMaster MiniProSC, have you tried the DigiMaster Pro3 as this model has CAT function built in, any feedback will be much appreciated. Chud M1PUP & 2E1BXW
Well honestly I was really disappointed that there wasn't a product between the MiniProSC and Pro Three for my 817. A product that has cat control and built-in audio interface and 1 books without all that extra stuff I don't need on the Pro 3. My Yaesu ft-891 has a USB port for cat control, so no need for the P to 3. The Pro 3 would be perfect for the 817 for a desktop or shack use.

You inspired me to attempt the same thing with a rpi3, raspian stretch, a cheap sound card ("Daffodil") connected to a mchf clone (rs-918 and an ordinary mini-USB port to 3.5mm AUX Microphone Jack cord.
I'm getting this error: "Hamlib error: communication times out while getting current frequency". Also the Test Cat button in wajx-x remains greyed out.
imgur.com/a/sTfE3lu
Can you please tell me what I'm doing wrong?
Hi Julian,
how do you link fldigi and 891? Which radio model do you select in cat control settings?
Yes I use FLRIG for cat control. It's not perfect though. Fldigi needs lots of work for 891 :(
As I see the latest hamlib has FT891 support marked as 'Stable'. And fldigi can use hamlib for rig control.
Didn't test it yet but will do.
Hey did you send me an email? I think you asked me for something which I have forgotten about
Yep ))) it was concerning 891 revisions/serials and cat noise issue.
Awesome, I've already taken the pictures and I'll send them to you this morning after I walk my dog :-)
I was hoping for more detail on how you get from 12V on your battery to 5V on your Pi. Also, I’m getting a lot of the dreaded “lightning bolt” when I run my Pi with external USB connections and WiFi. I’m concerned about pulling too much with that 3B+.
I'll do a blog post tomorrow on the DC power aspects, then share it on the community tab of my channel. The reason I did this kind of overview is it just takes too much time and energy to make such large detailed videos.
About the lightning bolts. Are you running heat sinks on your Raspberry Pi? You see what I'm running on my Raspberry Pi. I have the GPS, Wireless, a second wireless adapter when I'm home so that I can still access the internet, and I don't have any problems at all pulling the amps. Let's try to troubleshoot your build
I an using a DROK 12v to 5v Converter as a HAT on the Pi. Description: 12v to 5v Converter USB, DROK Voltage Buck Regulator DC 9-36V 36v 24v 12 v 9v to DC 5 V 5A Power Supply Module Volt Stepdown Transformer Board with Dual USB Output Port

I have not tested for RF interfrance yet.
I have a "cigarette lighter" port I hook up to my 12 volt battery. I put the phone charger adapter in it, plug in my usb charge cord, then plug in my raspberry pi. If I am near a sunny spot I pull out my Solar Panel which has usb charging ports and hook the raspberry pi to it. I get the lightening bolt sometimes when I plug my Signalink into it. I got to figure that out.
@@OH8STN What is the link to that post?
I have multiple posts can you be a little bit more specific?
How about some sort of shield for the Rass?
Can you elaborate?
@@OH8STN for single board computers like the pi there are extentionboards like the batteryboard. These are called shields. Why not building a shield that contains some form of transceiver. Just plug in and program.
Drawback: I don't know what the output does tot the board and if you have too shield the RF.
Plus: small, all-in-one and fully compatible with the pi if good designed. Connectors should not be nessisary and free for other uses. QSL? 73's
Did you ever get the GPS working with Pi-Star ?
Pi Star? Sure it was me?
@@OH8STN I hope so. You got the experience with debian and many linux programs for hams. Would love to see a vid on that.
The thing is I don't have a pi star, but I do have a video on sitting at the GPS. It might be dated already but it's in my Raspberry Pi playlist.
How did you connect the pi to the power distribution?
That's the one thing I haven't made a post on. If you give me a couple hours I'll make a blog post on it.
I can describe it here briefly. I built one of the 4 port powerpole kits from www.k9jeb.com . All four ports have powerlines, but I'm one of those parts I made a adapter for the Raspberry Pi. I used an adafruit buck converter with ~9-18v input, 5v 2A usb output, with 15A powerpole on one end, usb out on the other. That's how it's wired now.
In the near future, I'll replace the USB buck with a wide input voltage Buck converter, with 10v 2A output. That will be wired directly to the regulated voltage input port, on the Pijuice hat.
@@OH8STN thank you.
Julian, drop the external USB GPS and run a time server on your tablet since both are on the same private network. If your tablet has a Qaulcomm chipset it has GPS already. play.google.com/store/apps/details?id=com.icecoldapps.timeserver. Love the videos!
interested in this option
How did you setup the pi as an access point?
Hello Douglas .
I just updated my blog on Raspberry Pi for Ham Radio which includes the access point.

Thank you. When i upgrade, i will see if i can.
I have gotten it to be standalone. Where would i find to get it to be regular wifi when at home?
Do you have somewhere i could get the coding so that it can switch between access point and the home network?
Non HAM operator here. Can someone please fill me in what ham operators actually do? Is it simply looking for a frequency to talk to someone somewhere else in the world? What is the point of the radio equipment?
Actually ham radio operators do a lot of different things. So there's no one single right answer. For example my radio equipment is used for emergency communications in a grid down scenario. I also use my radio equipment when I'm far away from home, hiking and camping above the Arctic Circle, in places where no mobile phone service exists away from main highways. Of course there's the fun aspect of ham radio. So I also use ham radio the way some people use forums or Facebook. It's kind of like a wireless social media Network of like-minded people. Does that make sense?
@@OH8STN ah ok thanks for the reply
Or you could just carry a 12V power supply, mcHF clone, netbook/laptop, and avoid all the “layers of complexity” you have successfully managed to employ. SDR radios with built in sound card and digital modes/waterfall display are the future. Manufacturers just haven’t caught up yet...
The original mcHF is awesome but the cable mess with a laptop doesn't solve any problem. Sure the radio is smaller but there is still an external battery and limited 15w tx out. We also can't power most laptops from 12v, so some dc booster/regulator is required. How do we integrated the laptop into our portable power strategy without adding weight & complexity!? Finally, being tethered to a laptop is "easy", but not fun. The MCHF with a Raspberry Pi would be a nice QRP Digital kit.
OH8STN the laptop is optional with the mcHF, and that’s what makes it awesome.
I've been reading too much of that Chinese marketing from the fake one :-). The mcHF only does psk31, It can't handle any other digital modes on its own. I get where you're coming from, but I've done an incredible amount of research on that rig and many other qrp rigs.
I see. I thought it could do more than just psk stand alone. FreeDV is built in for sure (digital voice) Anyways, point being, the radio manufacturers need to take a tip from this radio, and others like it, and build in these options. If they go %100 SDR, more modes could always be added down the road with firmware upgrades. I know I’m preaching to the choir telling you this, but the mcHF is a perfect example of a radio that could have a new firmware package put out tomorrow, that added support for all the digital modes currently in use. An open source radio could even have firmware built by it’s own user base.
Where do I sign up? To be honest, I'm waiting on the "mcHF Pro" 👍😉
Thank you very much sir! 73 de Lz1mak/ kc2yzl
