Get Out - Portable Ham Radio!
LoRa APRS: iGate and Digipeater
As Norwegian ham radio operators just recently got permission to use up to 200kHz of bandwidth in a small part of the 70cm band, it's time to finally set up a LoRa APRS iGate and Digipeater. It's a really simple process thanks to the most excellent web-installer offered by the creator of the firmware. You'll find the firmware and web-installers here:
github.com/richonguzman/LoRa_APRS_iGate
richonguzman.github.io/lora-igate-web-flasher/installer.html
The board I'm using is this one (but the same board is available form all the usual places):
www.ebay.com/itm/405019752606
Remember to get a unit for the right band for your part of the world. For Europe, that should be 433MHz.
Looking forward to hearing your beacons on my next road trip!
Until next time; 73!

Ham Radio in Space: Building the EggNOG matching and phasing unit
Переглядів 23714 днів тому
Ham radio via Low Earth Orbit (LEO) Satellites has been a fascination ever since I got licensed. Working LEO satellites is must certainly a challenge, but it can be done with relatively low-cost equipment. As I'm hoping bot to work birds with FM repeaters as well as digital modes, I've long wanted to get either an QFH or an "egg beater" antenna up. The QFH can potentially be challenging for an ...
ICOM IC-705 from a USB power bank
Переглядів 71121 день тому
The next part of my journey to discover USB power nirvana. I tried to take the IC-705 out with the USB trigger cable and a power bank, but discovered to my dismay that the 5.5 mm barrel connector didn't fit. Turns out that 5.5mm barrel connectors come in two variants. One with an inner diameter of 2.1mm and the other with an inner diameter of 2.5mm. Luckily I also have a few "USB trigger PCBs"....
SOTABeams Carbon 6 vs HRD Industries Lil Dude 6
Переглядів 23621 день тому
I've been collecting parts for a truly lightweight portable radio kit for a while now. For masts my two contenders this far is the SOTABeams Carbon 6 and the HRD Industries Lil Dude 6. Join me for four and a half minutes of measurements, opinions and general waffling. Spoiler alert; only one of the two will get the LB5JJ seal of approval!
USB C Power for QRP - Part 2: Measuring Ripple
Переглядів 180Місяць тому
After my previous video on using a USB-C "trigger cable" for powering a QRP ham radio, my friend and fellow presenter at @hamshoweu @LB4FH made the good point that the usability of such a solution would be very much dependent on the noise from the USB power bank. So I decided this was a good excuse to bring out the oscilloscope and try to characterise the ripple from the two power banks that we...
Testing USB Trigger Cable For QRP Power
Переглядів 196Місяць тому
In yet another attempt to lighten my load for ham radio POTA and SOTA outings, I got the idea that a normal USB power bank and a so called "trigger" cable may be useful. I ordered a small selection from everyone's favourite ubiquitous action site and set about testing both the cable and my power banks ability to deliver current through it. Conclusion so far is pretty positive, with the power ba...

De-boxing Day #003 - WSPR Transmitter for comparing antennas
Переглядів 1215 місяців тому
I've been told that opinions are like arseholes; everyone has them! And that's definitely the case when it comes to antennas for ham radio. So, to try and separate facts from opinions, I ordered two WSPR transmitters from ZachTec. The plan is to use these for side-by-side comparisons of a range of HF antennas, and to be able to make decisions based on empirical evidence instead of unsubstantiat...
Small, lightweight balun choke for QRP operations
Переглядів 1605 місяців тому
(Excuse the mumbling in the last half of the video, I think I forgot I was talking to someone other then myself) I recently took delivery of the 6m carbon fibre mast from Sotabeams. Planning on getting together a extremely lightweight and compact kit for portable radio. Starting with a simple choke balun for QRP dipoles and verticals. Parts used in this build are: - T68-43 toroid - About 50cm o...

“Probably the best igate in the world” #ihopeyougetit 😊
Many thanks, following your instructions I configured my igate perfectly. Which Lora board do you think to use as a Tracker?
Thx for your video :) I´ve just connected my PowerBank via an USB-Trigger and a pair of 4A-Fusions to my Icom 705 - and it works great. The internal Accu will be charged and and RF-Power is at 10 Watts. Very cool
Excellent stuff 👍🏻
Thanks 😀
Great info, 73 from CA2RXU ;)
Thanks! And thank you so much for the really nice firmware and especially the extremely smooth installation and configuration experience!
You forgot to set Chrome as your default browser.
No! I really didn't! 🤣
I came heard from Smitty’s post
Welcome!
This is a much better assembly video than I could ever produce. Thank you SO much!
Ah; thank you for the nice product! Looking forward to getting it up on a mast and testing it!
One of the cheap inline voltage monitors is nice. Put power poles on both ends and you can use them to monitor voltage and current going into the radio. I keep one with each rig. You might not want the extra weight on SOTA but for a normal drive up parks on the air event its a nice to have. Thanks for the video Bob! 73
I was actually thinking of creating a cable with one of these 3 digit 7-segment voltage display that you can get on eBay. Not a precision instrument, but probably accurate to with 100mV...
A little trick I have used is to tack one connection then check the alignment. You can then re-flow the tack to straighten it. Once its in place complete the soldering. Looks like a well put together kit. Thanks for the video! 73
Yeah; that’s what I should have done instead of that dumb-arse heatsink^h^h^h^h^h^h^h^h machinist square. I have another kit for 70cm; I’ll make sure to do that when I build that one!
Nice!
Creative intro! good work
Thanks! Working on finding the balance between short and entertaining and long and annoying. I think this one should have been 2-3 seconds shorter…
If you have suggestions for a name brand power bank that will deliver 65W or even more at 12V PD, please get in touch or leave a comment - thanks!
I don’t think you can get 65 watts @ 12V over PD. You need to go to a higher voltage if you want to get to wattage that high over PD protocol
Looks like you're right. But is the cable is capable of 5A at 20V, there isn't really any reason why you can't push 5A at 12V too. So it's limitation in the standard I guess... With some luck I'll find a power bank that just limits to 5A whatever voltage is negotiated with PD - or I find one where it's possible to hack the firmware!
@@LB5JJ ooooh a hack able firmware now we are talking
I love mine as well. N5BSB
Thanks for the comparison. I could always have you measure that second element of the sota beams and make a cap for it also. I would put it on thingiverse for others too. Thanks for the 🦭!
The top element of the Carbon 6 wouldn't hold the weight of any sort of cap. It has already broken once, and that was from just looking at it funny!
What about the second element?
Love the seal of approval! Thanks for the video Bob! 73
Yeah; been wanting to create that for the longest time - and a well deserved first recipient indeed!
Great walkthrough and inspiring me to check mine as well.
Thanks - fun exercise. Always interesting to get a glimpse of some of the invisible things that influence us whether we like it or not!
So there is a bit of difference. What I noticed was a lot of noise when for example charging phones while on the radio. That was with the Biltema powerbanks, the old edition. Nice video and walkthrough!
That might have been switching noise and not ripple. All the measurements in this video was done with the 20MHz filter on the scope engaged. Characterising the switching noise it a lot more challenging. I'll try out the "Biltema" power bank on the '705, and if I do detect anything that could be caused by switching noise I may do another video on that as well.
Great job! The B.B. Link adapter provides CAT control access, so you don't need to set the frequency on the radio beforehand. RadioMail will automatically change the frequency based on the station you choose to connect to and will restore the original settings once finished. Also, I approve of the beer choice!
Didn't know that; thanks! And thanks for both creating both RadioMail and the B. B. Link as well; shameful that a US$750 radio sold in 2024 doesn't support BTLE, but really happy you found such an elegant solution!
That looks like a nice solution, would be great to just do USB-C for radios as well, as long as the powerbanks doesn't make noise. That could be something for another video 😉
Way behind on answering comments here. But as you've already seen I've done another video trying to characterise the ripple on these two power banks!
I have had good luck with the Talent Cell's. Typically 6aH version. They are available on Amazon in the states. Not sure if they are available in Norway. Thanks for the video Bob! I see you got one of the VR-N76 HT's. Its on my list of next Ht's to purchase. 73!
Thanks! And yeah; looking forward to trying out the VR-N76. Got it primarily to satisfy my APRS "fetish", but hoping it may even be a decent daily driver type radio for when I don't want to drag the US$750 Kenwood around!
but good video
Thanks :-)
0.0 just why vy 73 de oz1rd
I don't think I understand the question...
Awesome Intro... I waited for the clay-figure animation. 😉
Oh; I'm not done with the stop-frame shenanigans yet :-)
Nice video! 73
Thanks :-)
Your message is received. Nice video!
Thanks; fun activity - looking forward to tomorrow’s stream!
If that boat trip turns into a 3 hour tour you have enough battery to last all 3 seasons of Gilligan’s Island!
At least :-)
I liked how you made the tuning capacitor, inside the loop, and the coated copper pipe made for a very tidy build. Nice job. Thanks for the video.
Thanks :-)
Is it a ham antenna or cb one
6m ham band
Looks like a nice start for a project 😁
That’s almost 20 kg of aluminium, so hopefully it’ll be enough for quite a few projects 😀
Just subscribed
Welcome!
I have to try this. \
Good luck, and let me know how it turns out!
I keep looking for you on FT8! I saw you once but couldn’t make the connection. Take care, N3OA
Looks nice!
Funny you have just published this as today I've just finished my 6m mag loop too... An offcut of elliptical waveguide rather than plumbing pipes. A coupling loop rather than the ferrite and a small butterfly rather than your co-ax inner. Just over a foot in diameter but just like you I'm very impressed with it's performance. Picking up Slovenia from inside the kitchen here in Scotland. Q is very high (showing good low losses) & certainly need to retune the capacitor depending on where in the band working. Totally agree with you that these little mag loops can be great fun to build & play around with & that they can provide amazing results in restricted circumstances.
Nice work! Sounds like a piece of kit! Looking forward to further experiments with magnetic loops in the future. If have some pictures of your build (either "in progress" of finished product) feel free to share!
Opinions are like assholes everyone has one that they cover up!
The hydration technique used was probably the most important step. 🙂
Tou finally made it a short
US2IX 👍🤝🇺🇦
Why didn’t you include video showing the DX contacts?
You're making great progress. Kudos!
Thanks! Looks more impressive then it is tho'. The "CQ" and "LB5JJ" are muscle memory by now. I couldn't send anything else nearly as smooth :-)
It does look a wee bit warmer there than Norway at this time of year.
I recently hiked mt Whitney which has a summit around 15k feet. When the snow melts I plan to go back but I’d like to make some contacts while I’m up there. What would be my best bet for gear? Some sort of dipole?
Weight is the key! You don't normally need much in the way of an antenna on a mountain top. If there's mobile phone coverage, I'd recommend spotting yourself - you'll have a pile-up in no time! Be careful and good luck with the activation!
What's the white stuff on the ground? Is that white sand? LOL! I from the Central Coast of California where it's about 60 degrees Fahrenheit or 15 to 16 degrees Celsius year round. Looks cold, fun, but cold. 73
I used a stepper motor and an Arduino for my Mag Loop years ago. I ended up giving it to another ham though. I miss it now. 🥲Great Video. Thanks for sharing! 73 de W6OBB
What a beautiful day.
awesome video!
Didn’t understand this at all but it certainly is vibey 💃🕺💃🕺💃💃💃💃🕺
This is also a way to motivate you to learn CW. Because in the end, now you have to! Owning a Bengali and not using it is probably an unforgivable sin…. 😝
Awesome!
