- Hello Operators.
Each of us has a different idea about what the ultimate raspberry pi build would be or look like. For my station, reducing the cable mess, replacing a large audio interface with a low cost usb audio codec, and creating a lightweight, energy efficient configuration for ham radio data mode operations. Also important was getting my raspberry pi to work off os 12 volts, just like my Yaesu FT-818 and Yaesu FT-891.
In this video, we will go through all the hardward, hardware mods, hats, and software used to make this station the ultimate rasberry pi build for ham radio data modes in the field.

Fantastic, I've been working towards the same goal for a couple of years. Going to be a long night.. One question what was the Android terminal you used in the video? It looked fairly well built physically. Thanks, I'll check out your other videos.
Hi! I went on your site to find more information on how to get the Pi to create it's own network and the link to the Pi site is broken. I searched all over on how to get the Pi to create it's own network but everything I can find requires an ethernet connection. Do you have more information on how I can configure my Pi 4 to create a network I can connect to with a tablet to run VNC with no ethernet/wifi.
i have a question. what would i need to know to know how to build my own HAM. is there any programming that would be beneficial and if so what program would i use and also what hardware?
Your best quote ever, "the need to get MS Windows out of ham shacks and away from Emergency communications". Now if radio vendors will listen, we can make some head way to getting better programming software. Thanks for this video and everything you do and share! Keep it up! I like being part of the amazing things you do!
That was still true until recently. Unfortunately emergency communications is still stuck in the windows ecosystem. I would love to use a MacBook or Linux system exclusively but, development and these other systems he's the lacking from an emergency communications perspective 😥
I believe you are changing the way future radios will be made with this video.
I hope you're right. There's no reason we aren't there already.
I always look forward to your comments. 👍
Icom ic-705
I am a new lurker but a HUGE supporter.
Your programs are the motivation that I needed to go beyond the local FM scene. A newer licensee I may be, yet I'd hung up my PTT for several years, because the overall motivation and aim of local emergency services groups didn't quite meet the expectation of what I'd hoped to find.
Thanks for the introduction to and virtual mentorship for man portable, HF field ops and overall system integration!
IMHO, your contribution through YT to the amateur community is tremendous, and without parallel. Thank you Sir a thousand times over for all that you do.
Julian, unlike so many Ham Radio UA-camrs, your dedication to actually providing helpful content without extraneous verbiage stands alone. Thanks for a great channel!
Love this comment. Keeps my feet on the ground 🙏👍👍👍
I realize this is an old video and you have since moved on from this setup so just consider this a sacrifice to the algorithm. Great video as always.
I’ve been following you for about 7 months. I know this video has been around for a bit, but I wanted to mention how I’ve enjoyed coming back to your channel when I learn something new to learn (more) of something new. 👍🏻
Excellent video as always Julian. There are two key take-aways from this and similar videos. 1. You actually use your gear in the field under field conditions. 2. Taking gear into the field, you quickly find out where the excess weight and hardware flaws are.
I highly encourage everyone who is truly interested in field ops to pack everything, carry it around their yard then deploy it in the backyard without going back inside for those "other parts". While very basic, this will still show you where you're carrying too much or what you're lacking. Once you can walk to your backyard and get on the air without external support, expand it to the neighborhood ballfield...rinse and repeat. These small, simple tests will quickly show where your deficiencies are and will make for a far more effective and enjoyable deployment in the future.
As for me, my next "deployment" is Winter Field Day 2020. Hope to see you on the air.
Holy smokes! I love this information. I'm a new ham, just earned my technician 2-22-21 then general 3-22-21. This is the stuff I want to do and learn!
Julian once again you did a really fine job with the video. AmRRON, just WOW! What an organization and what a powerful script.
Thanks Anthony. Yeah, AmRRon. We really needed a partner like this for the channel. 👍
Another great video, so glad you talked about the DRAWs Hat! I can't wait until you post more about your experience with that. I love your dedication to specific requirements and why manufacturers are failing by not engaging their customers (or at least customers like us) in their development process. Keep up the excellent work!
I wish i could give MORE than 1 thumbs up - excellent as usual!
Don't worry you'll have another chance in the next video when I take the Raspberry Pi to Lapland :-)
Thanks for the comment and the kindness, It's very much appreciated.
Great video! I love seeing the progress and experimenting followed by the solutions you end up with. As a relatively new operator with an interest in off grid/emergency Comms, this is exactly the stuff I love learning about. Great work and keep it up! Thank you for all your work.
Every time I watch your videos they make me want to build more. I have built your radio packs already, so now I need to get over my fear and jump into Raspberry Pi for my 891. You've done a truly great job! 73, K8JLW
Best radio content on UA-cam. Amazing work yet again. :-)
Wow, that was impressively detailed and awesome. That gives me a bunch of ideas.
You have made excellent points on how to build a portable station. I am a fan of the Draws hat and use it for most of my ham digital modes. I agree it needs help with the software because we do not have the drivers for it. You made us look at cabling and exiting from the rear is importantance. Some manufactures get it but most do not. You keep driving us to a simpler more useable portable ham system. Thank you,
I had a couple of HAM buddies and their wives over for dinner last night and the topic of conversation eventually turned to you. I realized I had watched a couple of your videos quite a long time ago but had forgotten about you. Logging in today and watching this video I can see I have missed quite a bit. I will be catching up on your excellent videos. Thanks for all of your efforts!
Awesome comment. It's taking me awhile to understand what I'm passionate about, and how to present the message. Those old videos were all over the place. I guess I was trying to make too many people happy, ...
Thanks for this comment, and support. It's very much appreciated.
OH8STN: Outstanding video!!! Even though I specialize in portable CW, I still integrate my RasPi-4 with my gear as assistive technology. I have learned a few more things that I didn’t know about the RasPi configuration for Amateur Radio. Thank you & 73!!!
Man, where has this channel been all my life. This dude is a genius operator
This video seems like a capstone for all of your previous Raspberry Pi, tablet, & soundcard videos, but I know you're just going to continue to adapt and evolve. I was so happy to watch this video this morning. Keep up the incredible work! 73 de KI7POL
Yeah we've definitely come a long way since sitting in the freezing rain getting frostbite with the 817 and tablet. 👍😀
The amount of effort going into these videos, is driven by the field testing. Without the field testing, the evolution can't happen. Comments like yours let me know the recipe is working. Thanks for that.

Julian oh8stn
Just came across this... Love it! So many new ideas from it. Great job Julian!
Another great video! I always get some great ideas from your videos, thanks for taking the time to make and share! 73
I agree with you 100%!!! I am tired of the rats nest of wires we have to contend with wether it be field or ham shack centered. Once we can come up with a very clean and compact digital station it would be nice if someone could create a weather proof case sized for field use. I love the Pelican products but a case with a view would be nice no matter how remote we make the station to interface with an external device, I still like to keep an eye on stuff within the case. I have used in the past an industrial spray on silicone conformal coating that protects the board from condensation issues however the problem remains with the interface ports of the Pi. All of its connectors are the weakest link in keeping it dry and operating properly.
Keep up the great work and research, looking forward to the next video!
73!
Great video - will be rebuilding my FT857D portable setup , this streamlined configuration will make my travel less bulky.
Fantastic content. Thank you. Newbie Ham in UK. Currently studying for foundation Licence. Ex-RN Radio OP keen to go portable cw ops. Keep this up. So valuable.
Love your work. Just getting into the Ham/R Pi field, enjoying your videos. Keep up the great work. Cheers from Australia
Thank you Greg. Comments like this, make it easy to keep moving forward. Thanks for this, and the kindness you showed earlier. 👍

I found on Amazon a board that takes a very wide voltage input and has a fan to keep the Pi cool. It also has a switch to shut down the Pi. Not sure if it cuts power or does it normal software shut down. I think it has the pins on it to put another board on top of it. If so then you could put the board with the power supply and fan on top of the Pi and another board on top of that. This may make the Pi start to get taller, and not easy to find a case to fit it. But it will take something like 9 to about 16 volts, keep your Pi cool and give something like 4 or 5 amps of power to the Pi. I don't think you will need more power than that. But everyone has what they think is most important for their application. THANK YOU FOR THE INFORMATION YOU GIVE!
Sounds like a good one. Be careful with the fan Cooling. Fans create noise on HF. If you don't live in a terribly hot environment, passive cooling is definitely better. Anyway without seeing that bored, it's difficult for me to answer if another board can be stacked on top. I think the best bet would be sending a message to the seller Anne asking about the stacking capabilities. If designed correctly, it should be no problem.
@@OH8STN The best part is the buck convertor to take 10 to16 volts to 5 volts with power leftover for the Pi 4 to 5 amps at 5 volts. Not sure if it will make noise, it said low noise but that could be sound. I think there is a way to switch the fan on and off if needed. I live in south Florida. If working Pi4 the fan may be needed. Working outside with 95F weather fan may help. I will check on some things and see. Don't know if a Pi3 will need a fan. The fan has a plug to the board so can be unplugged. It does have the header pins on top of it to put another board on top of it. Just a idea if you want. It does use a plug coming out the side but it looks like you can put wires to the board and run them out the back and put power pole on it. My next 2 disability checks are spoken for but I want to get it later this year. When I get it I can tell you more about it.
Great Julian, I loved the Real Time Redundant clock idea. Excellent quality video , as usual.
Thank you 🙏
Julian oh8stn, your approach toward radio communication development is highly appreciated. Your methodology to convey vast experience into hands-on build with reasoned explanations makes this subject easy to learn. I thank-you for for sharing through UA-cam. I pre-ordered an IC 705 and intend to obtain a first time operator rating through a local club located in Renton, Washington. Looking forward to future projects focused on an IC 705. All the best to you and your family for this Holiday Season and the New Year.
Hi Julian, great video. Couple of notes: The FTDI chipset "problem" was designed into the *Windows* drivers to attempt to stem the flow of cheaper Chinese chips. Linux systems (including the RPi) don't care if the serial chip is "real" or "fake", they both work just fine. Also, if anyone is concerned about putting audio signals from the audio interface directly into the radio (can go bang), cheap 1:1 transformers (in the form of "ground loop isolators" of the sort you can get on eBay for pence) are the way forward.
I feel very grateful that I found your channel ♡♡♡ fabulous video 🤜🏻👍🤛🏻
Always Great production values Julian. I need to work far harder on my ham radio videos!
I don't know about that Richard. We have different goals.
The RPi4 arrived yesterday, and was used tonight on FM without a head to check into the local ARES net using FLDigi. Way cool. The AmRRon scripts were indispensable to the effort.
Excited for the arrival of LFP cells and components this week to build a battery, and then off to the field for R&D trials on HF using a rotary dipole that I've assembled for the same purpose.
There is still much left to learn and build, but so far, its not a bad start IMO.
None of which I could have accomplished were it not for your contribution to the radio community. TY Sir.
I like commsprepper, ham radio concepts, world gone silent, but your channel is awesome.
I also like commsprepper, but admittedly I'm a little sad that he's not making so many videos anymore. Eric has a nice channel. He can get people generally motivated about the hobby. I don't know that other channel. My favorites Communications channel is GuerrillaComm. He doesn't make that many videos anymore, but he has a solid library on UA-cam. If something seen in this channel is useful or entertaining to people, it makes it worth the effort. Thanks for the comment. It's very much appreciated. 👍
Very informative and fascinating. Great job!
Very innovative Julian. Awesome to see your ideas!
Outstanding video... just got a RPi 4B for just this purpose, and you've given me a lot of fantastic ideas on how to make the best use of it with my 706mkIIg. Thank you so much for sharing the information!!
Awesome video, thanks for what you're doing to push off-grid amateur radio ops!
Wow ! Just managed to watch this. I'm out of breath from just watching ! Awesome job putting that together. Thanks again for all you do and pushing this genre of the hobby forward IMPO. 73 de 2E0IEH
A Great video that I will be watching several times to configure my next RPi station interface. Great Job !!
Thanks Terry, much appreciated. 👍
Julian, thanks for other gem video. Your passion for our hobby is amazing!
Very nice and informative video. Keep up the excellent work.
I found this video very informative & easy to follow along. So much so that I bought a Raspberry Pi 4B along with the other accessories shown & have it almost all assembled. By 1AM this morning I was receiving a WeFax transmission using FLdigi. Today's goal is to have it transmitting and figure out how to use the pi's BT to communicate with the wireless keyboard (if possible). Looking forward to your next video - thank you!
Thank you Julian, very helpful as always.
Great job. Thanks! I have the 891 and will definitely use this.
Amazing video!! As a new ham this is the exact setup i plan on building ! Thank you!
excellent video and explanation OH8STN.
Hello Julian, thank you for your extended video and the good explain how we can get it better.
best greets from germany,
jan
One word. Inspirational. Looking forward to the next video.
Lots of great information. Thank you
As usual a brilliant video thanks very much have learned a lot from all of your videos please keep them coming my very best Regards Rob
This is an amazing video. I am new to Ham and you have inspired me to take up the hobby.
Your videos are super inspiring and informative. Looking to get into portable HF coms and want to include digital modes. The information you present is a bit overwhelming for the newbie but as I start to understand more generally, your presentations start to click in my brain. Keep up the good work. 73
Great video mate! Just found you and subbed. Kind regards from VK3 (SWL).
You are amazing sir. I want to incorporate the Raspberry and add-on to my rig.
This is so far over my head I cant even comprehend! That being said, very cool, and I would like to know so much more about it!
Another awesome video, thanks very much!
Excellent content once again Julian. I really need to get my Pi configured with the latest versions of all the various software. I've also ordered a batch of those buck converters so I can revert my PiJuice hat to use a standard power pole link from the ammo can battery box. 73 my friend. G1AW
Thanks for the comment Andy. The Raspberry Pi is becoming more powerful, and easier to configure. I guess it's up to people like us to see how far we can push it :-)
It's always good to see a comment from you. It's always very much appreciated.

I'm have just recently passed HAM licensing exams here in the Phils. If it were not for this pandemic, I might have already gotten my license/callsign, but I have to wait a little longer to do that. Having that said, your videos inspires me to the fascinating world of radio communications, especially your practical ways of doing thing. Keep it up Sir. Thank you for keeping it interesting. 73.
Congratulations on getting your amateur radio license. Hopefully you'll get your call-sign pretty soon. Hey thank you for this wonderful comment, it's a nice way to start my day. Hopefully this channel can keep you interested and inspired. Your comment has certainly inspired me. Thanks for the kindness and the feedback oh, it's very much appreciated.

Great Video as always cant wait for the DRAWs hat video. I am building my own setup with a Yaesu ft-891 and a Pi based on your setup. Have you thought about building your own Hat with all the things you want on it and cable outputs configured to the back? might be a market for it!
Great video indeed - improving our rigs from 'out-of-band' knowledge and making them smarter!
Thank you 👍
Extremely well presented
Awesome video! Thank you for blazing the trail, and thanks also to AmRRON for their work.
I completely agree with the reduced cable clutter and single power requirements for field work. I see the attraction of VNC control, but I'm still leaning toward a dedicated LCD and folding keyboard, with everything tucked into a box to protect it during transportation. Wireless control is great and allows a lot of flexibility, but I don't want to power the radio station and a tablet or notebook. If not for the weight and power consumption, I'd be tempted to eliminate the Pi and use a rugged notebook for rig control and digital modes, basically a field version of the QTH shack.
Like you say, I hope manufacturers start to understand field use and make more integrated radios. It honestly wouldn't take much to make a turn key solution with an integrated low power Linux computer (Pi or equivalent) that could be upgraded as new software is developed.
It also strikes me that, while it's great for everyone to run scripts or otherwise configure their own systems, there is also a market for people who would like to buy a pre-configured Pi with a radio specific control cable. There is plenty of opportunity to experiment with system packaging, solar power, batteries, power regulation, antennas, etc. If nothing else, I have cellular internet and downloading a 17GB bootable Pi image would bust my monthly bandwidth limit.
Similarly, Northwest Radio needs to make downloadable images that Just Work (TM) with a Pi 3B and Pi 4B. Integrated hardware isn't much help when it takes longer to configure the software than it takes to buy all the hardware modules on Amazon and configure the software for these non-proprietary bits of hardware. And yeah, the cables connecting to the DRAWS hat need to be on the same side as the Pi cables. That seemingly small detail is, almost by itself, a deal breaker.
I have the single jack TRRS version of the Sabrent USB sound adapter (as opposed to the MIC and PHONE ports) which makes the homemade cable slightly more compact.
Thanks again for another excellent video. I have two Raspberry Pi's sitting in a desk drawer inches from my laptop. It is my plan and has been for some time now, to get a portable digital station up and running. I've been inspired by your portable field tests and ongoing gear development. It's my opinion that Linux is clearly the way to go for portable emergency communications. Less expensive get which is totally man packable has a clear advantage over something which can only be moved with a vehicle. Likewise, gear that has a low energy demand and can be recharged via solar makes total sense. I now have the power supply side of a field station completed so can actually operate man-portable but only with phones mode. As winter sets in here in Canada, I hope to have more time to get the Pi out of the drawer and start working on the digital side of the station. Thanks for your continued inspiration.
Thanks Marvin.
The only thing that limiting Linux absorption for newcomers, is a lack of good documentation and tutorials, specific to our working tools. Even with these challenges, integrating the Raspberry Pi with our rigs, has clear advantages for station deployment and operations. It's not perfect, but we're certainly getting there.
The next video will be a field test of sorts.
Can you wait Marvin oh, thanks for the comment feedback and kindness. It's very much appreciated.

Just found your channel and this video in particular. I have a lot to learn but what you are doing resonates with what I want to do with radio. I'm a new ham two years and primarily do SOTA and POTA. I only have an Elecraft KX3. No base station, no mobile. Everything in my backpack. Just SSB to date. Need to learn CW and digital. Although I'm having a lot of fun with this, off grid communications feels like the next avenue to go down. Thanks for the channel and I have a lot of your other videos to go through. 73
Welcome to the community 👍
For date of modes with the kx3 you want to get yourself a Digirig for cat control and audio. The Raspberry Pi is interesting but can be complicated on a summit. I would go with a surface tablet to keep things simple.
great video Julian :) Thanks
Very useful info. I'm planning something similar for my FT-857d mine isn't as much about grid down or emergency as it is about mobile operations but it will also do that too I guess. I want to be able to use voice and also have a waterfall display so I will also add a PAN Adapter tap and a RTL-SDR v3 dongle to the RaspPi. I might upgrade to a SDRPlay RSPdx when they are available. I plan to build mine into an 50mm ammo box and have the ability to remove the head and connect it remotely for use in my car. My radio should be able to work at home in my car or on top of a hill !
Looking forward to seeing the progression! Good luck 73!
Great video Julian!!!
SO GOOD👍 I need to keep watching more. This is October 2021 for me getting on board. About watching 10 or so more of your videos and I will start designing my first QRP station. I need much info and you are providing it! THANK YOU! The route of IC-705 is too expensive for me. Probably an RPI solution for me.
This is neat stuff!
I continue to learn from everything you have developed and posted. Did you do a video outlining how you move the Pi power to the rear of the pie. This is the part of this video that i found most interesting and an upgrade that I NEED to do.... likely I will buy another Pi specifically to develop the Pi-radio configuration. The Pi and rig as one analogy has rung true for me. Thanks Julian!!!
excellent...innovative .. forward thinking.. ty.7 3
u got new sub with this project i was looking for something in case of SHTF
I watched the whole video and I must say I only understood about 2% or it. The big hurdle for me right now is just how to get on the air -- too many life-intervention problems to solve first. But I applaud the effort to simplify ham radio and reduce the costs. Don't wait up for me... Leave the porch light on so I can find my way in the dark -- I'll get there eventually.
Thank you for the rich info. I am KN4VVY and love op JS8. I built a power pack after watching your video, using 8 headway batteries , genasun , ext. One thought about the buck converters.... why not just tap off the middle of the battery pack and get 6 volts. That should work for any 5 volt needs. Maybe with a series resistor to limit current and give a little voltage drop. Thx again. 73. I hope to QSO you on JS8 as I do see you there sometimes.
OMG, binge watching your videos!!!
Okay but be warned, some of them are bad :-)
Great topic as usual! Would you consider a follow up on the DRAWS hat and the pros and cons when compared to your current setup?
While I don't agree that every manufacturer should make it work the way you want (as they couldn't meet everyone's needs). I am however very intrigued with your setup and this is the best use of a RPi for ham radio I have seen. Thank you.
Thanks Eric. No need to agree :-) this is more about using my platform to give manufacturers new product ideas, and showing Operators what we can do with a little ingenuity.
Thanks for the honest comment oh, and kindness. It's very much appreciated.

Julian oh8stn
Fantastic!
Another excellent video, Julian. I always learn something with your videos. I am considering a raspberry pi for home and portable use. There will be a couple of different Pi’s but I will learn with the home version. I will look at your raspberry pi video to see the details of your setup. My first look at the pricing comes to between $100-$200 with case and power buc for 12 v conversion. All the best, hope you are doing well up at 65 degrees north! 73 de KI5HXM
DRAWS hat is magnificent. Nothing else required. Off to shorten my CAT cable and the mini-DIN from the DRAWS to the Radio - Graham, 2M0IJU.
Love this. There is much I don't understand. But that is my problem! I just got my license and still have MUCH to learn but I like what you are doing I just understand how you are doing it. Maybe in a year when I learn more I will understand more. I have some ideas but don't know enough yet to start putting it all together. THANK YOU FOR YOUR INFORMATION!
Hi Donald. Most of the confusion about what we do and how we should do it comes from not understanding yet what our own personal goals for communications or the Raspberry Pi are. That's a mistake each and every one of us has made in the past. We need to figure out what it is we would like to do even if it's just starting with one single thing. Once you understand what that one single thing is, we can start to put together a list of tasks to help you achieve that. Some operators want to take a lightweight computer on holiday with them, to run ft8. That's the kind of thing you should consider. So they don't put one less abstract goal on the table, then you can start assigning tasks to achieve that goal. If you look at it from the big picture as this video does, it becomes too abstract and difficult to understand. Does that make sense? Does that help you at all?
i really love your videos!
Thank you 👍
Fantastic stuff!
Thanks Eric. It's very much appreciated 😊
Two thumbs up... and no you are not too redundant on your choice for GPS plus RTC.
Great video!
I've started this sort of project a number of times and it has failed long the way somewhere or other. Thanks for the 'Poke' to get me started again. Installation script running as we speak. Thanks, Tony G8WBI
You are very welcome Tony. We all need some motivation from time to time.

I so want that rig. Saving this video in favorites. KD8RWC 73's
There is a board that goes on top of the Pi that has a fan and a built in buck converter that will take anything from around 9V - 16V in and powers the Pi. It has a plug on the side that is a pain, but there are pins inside near where the plug is that will take the power in. Things can be plunged into the top of it for more things can be added on top like the battery board. This board also has a switch to do a good power down on the Pi, also has a remote control but not sure if that is needed, just something more to keep track of. Just something that you may like to look at. This board is around $40, so it will not add a lot of coast. The fan runs all the time, not sure that is needed everywhere. I live in South Florida and it is hot in the summer some air moving on the Pi can't hurt, it doesn't use that much.
Brilliant!
A great video as usual. Have you though of getting a dead 818 radio case and putting the Pi and amp in it. Then double stack it with you radio for a neat set up. any switches could come out the front and be mounted at the face plate of the dead one.
Just went to the AmRRON site, and who's video did I see on the homepage? *lol* Fantastic work, Julian! You time and effort are greatly appreciated. You're definitely on the cutting-edge.
Seriously? Wow!😊👍👍👍
@@OH8STN Yes sir, seriously! :-)
Great one as usual. 73 de E73AV

Also where did you get the side handles for the 891? I have a set of Portable Zero's, but yours looks to have a fold out leg? 73, K8JLW
Great Video. Now to 3D Print taller side protectors and protect the accessories on top as well as the radio. :) w6akb
great video - i get what your doing
Thanks 🙏
Your videos are so good that I come back and watch some of them, like this one, again. Not that I’ve watched all of them… yet.
Is there a .xml control file for the ft-891 and fldigi? I’ve read that the 991 file has to be used. Or do you use a different method of control?
BTW I recently got the ft-891. Great deal and great radio.
Another great video Julian. I am also in the middle of building an ultimate Pi system for off grid communications. One question I have for you is where did you buy the two pin GPIO cables that goes to your buck (step down) converter? They look thicker (18 awg?) than the standard ones I have. Thank you in advance for any help with my question.
