Hello Operators.
In todays video is about off grid ham radio, and how we use our raspberry pi field computer, for off grid communications. We visit the cabin in Lapland, just above the Arctic Circle which serves as the staging area. Afterwards, we'll take the Nortent Gamme 4, raspberry pi, and Yaesu ft-817nd, heading out for some winter radio ops. This is all in preparation for winter field day.
In the previous video titled Ultimate Raspberry Pi build for ham radio, we discussed the strategy for an off grid Raspberry Pi field computer build, one we would use for portable ham radio field communications. In this video we take that Raspberry Pi to Lapland just above the Arctic Circle, to put the rpi powered ham radio station to the test.

Excellent rig you have there. Everyone likes to poo-poo the Raspberry Pi as a toy. We have the RPi's Foundation's industrial customers to thank for the surprising robustness of that little machine. Anything that can withstand an industrial manufacturing/forging process should have no problem weathering the outdoors; just keep it dry and/or conformally coat it.

A very effective video of HF portable ham radio, filmed in the Arctic with cozy wood fires, snow, and ice all around. Quite a good argument for the modular raspberry pi computer and accessories as the go bag unit. It shows how the use of weak signal HF messaging/ HF networking like JS8call is changing the realm of possibilities for operators. QRP-level text networking communication with positioning and selective calling is a powerful combination.

I have always been interested in Radio communication and this has convinced me to take a plunge into exploring these technologies. Me and my brother have been increasing in our adventures in both scale and seclusion. I was thinking about how this could be a practical tool for our overlanding and hiking adventures. You talking about sending a message to your wife with your location and successfully arriving at it sold me on the idea. I find your application of the raspberry pi very interesting and your decision to go with Linux makes excellent sense considering the customization, versatility and power conservation offered by the platform.

Great video. Totally agree with the "whole" station concept. My challenge has been to balance the weight of a capable radio system with the additional weight of life support and keeping it all in a man portable package. My challenge is to be able to run 72 hours without external support and be able to carry everything in a backpack.
@Steve-GM0HUU
@Steve-GM0HUU 4 года назад
It's not easy. Though I don't have a lot of experience, I have had a few attempts at carrying everything I need for 24-48 hours plus radio equipment. No matter how hard I try to reduce the pack to bare essentials, it still ends up weighing 40 to 50lbs. Unless you are very fit/strong, it's not pleasant carrying a load like that. One thing that weighs a lot is water which you have to carry unless you are 100% sure of sources along the way. Camping in an cold snowy environment has many disadvantages but has some advantages - I think I spotted a sled in the video. This obviously allows a much greater weight to be hauled. Also, so long as you have heat, you can warm snow so don't have to carry water.
@TXLorenzo
@TXLorenzo 4 года назад
@@Steve-GM0HUU I agree, one of the biggest challenges is water management. It is a big weight variable if you have to carry everything, hence the challenge. If you can base camp near a water source and daytrip to a hilltop, life is easier. It is an interesting problem set to solve. I am still working on it, LOL. 73s IU3JNT.

Cool use of the Pi. One suggestion, carry a spare Pi, and especially a spare of that SSD card. You can easily create the spare SD by using dd to make an exact copy of the card. Also, it would be really good to create a GitHub repo of a shell script, parts list, and whatever else is needed to prepare the Pi. I would be glad to help if this is outside of your expertise.

Just a tip for the other operators out there: The raspberry pi is not the only dog in the show. Take a look at some of the Orange Pi models as well. The Zero Plus doused with spray on conformal coating is another contender. JS8Call's rasbian stretch package installs fine on armbian buster. As a side note, has anyone looked at porting Jordan Sherer's 8-FSK modulation to one of the small wifi controllers like the 240Mhz Espressif ESP32-WROVER? It's got a fine audio grade ADC and DAC, due to it's bluetooth features, and it's about the physical size of that USB audio dongle you're using the DC-11F with. Alternatively, the 500Mhz NXP RT1010 might be a good choice if you don't need 2.4ghz wifi/bt, just USB2.0 (and one of the examples is a pair of USB audio endpoints.) It's the little brother of the Teensy 4.0 board, which has the 600Mhz NXP RT1062 on it, a little faster, but it costs about as much as a raspberry pi does, and doesn't run linux. The ESP32's about $3, the RT1010's supposed to be a dollar. I'd be tickled to see this slimmed down to fit on a $7 TTGO T8 module with a 6-Pin Mini Din soldered directly to it! Edit: This video demonstrates a USB host controller that could probably drive the Yaesu's control cluster. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-po3FBdY0GS4.html The microcontroller is fast enough to "bitbang" NTSC composite baseband video by abusing the DMA facilities. Slight modification to the PCB to swap those to either a mini-din or a pair of 3.5mm minijacks. Plug a logitech USB keyboard receiver into the other USB port. Continue to use the samsung as a display. Even without the samsung, can still blind-type on the keyboard, or pin a little ST7789 SPI display in.

Another GREAT video. Super informative. Super motivational. And like all of your videos, chock full of practical real world advice. Thank you! I've enjoyed watching and learning as you and a couple of others blaze this personal EmCom trail, but I've been lazily waiting for others to provide more of a turn key solution. Maybe I'll provide that solution for lazy guys like me. A Pi 4 with all the software, GPS, realtime clock, 12V buck converter, etc., pre-configured with CAT control for different radios. Sell it on Amazon and maybe eBay for $10 more than the component cost, after selling fees, more as a service to the amateur EmCom community and to popularize this as the EmCom standard. Markets play a large role in developing standards. I'd much rather YOU sold that product, Julian, given that you did most of the development and most of the promotion. Hopefully it'd be a hobby related way to support your channel, but it's sometimes true that turning a hobby into a business ruins a perfectly good hobby by making it into work. I completely agree with the idea of using JS8Call. I'm entirely sold on it. I can understand hams who want to use all the different frequencies, SSB, CW and every digital mode. It's all fun as a hobby but a hundred competing standards is no standard at all and that's not practical for emergency communication. What's needed is ONE reliable low power mode so everyone knows how to communicate. Redundancy is good, but not in com modes. Have redundant hardware to communicate on JS8Call, 40m & 80m, NVIS or DX depending on antenna configuration, and 2m or 70cm for local communications. KISS. I was reading your JS8Call messages. There was a character glitch. Freezing your WHATS off? :-)

Like the Pi for a remote control computer but then it would need Internet access in my vision of remote access. I prefer a laptop for "portable" use as it seems necessary for remote control of the Pi since the Pi does not have a screen, mouse or keyboard. I know you can add these things to the Pi but that brings "me" back to a laptop instead. Thank You for the videos keeps me thinking and "aware" of other ways to do things. . . ; )
@MyTube4Utoo
@MyTube4Utoo 4 года назад
I may be misunderstanding you, but the Raspberry Pi is perfect for this application, and there's no 'need' for Internet access, as that could be self-defeating if you need a quickly-deployable, highly-capable portable field ops. station that's deployable *anywhere.* Get a tablet, have software that supports your digital modes, install a VNC client, and you're ready to go. Obviously, a laptop works great also, especially if that's what you prefer.

You bastard! I'd just resolved to spend my next few paychecks wisely, but now I gotta pimp out my 817 instead! Have you made any major discoveries RE: measuring battery voltage from the pi, maybe using Python? I have an off-grid RasPi radio project of my own and had resigned to including an ADS1115 in the recipe and using Python w/ GPIO library to programmatically read and respond to power conditions. My off-grid deployment project will work in concert with a weather station to implement a rudimentary ATIS/AWOS and lights activation at a remote private air strip. The ADC is on the board, but It's not wired up yet because I have to research a necessary voltage divider to bring the ADC measurement into the 12v range, as well as fit a different radio with a smaller footprint -- but I'll post an update some day when I can afford to put all these projects back together :P

👍Good video, thank you. RPi is the way to go and certainly agree on the advantages of JS8CALL - a mode that has been around for a while and I am a little surprised that is not more popular, in EU at least. Though, I wouldn't perhaps totally write off other digital modes, especially Olivia, which may offer some advantages such as higher transmission rate while still having S/N performance close to JS8CALL.

Great video to see how this is all coming together. I am about to start a similar journey and the research is very helpful. I also really enjoyed the lessons learned from last winter field day hope you do the same this time. My set up is going to look similar while independently choosing some of the same equipment hopefully a good sign I am on the right track.

Hi. Very inspireing info. My Raspberry Pi 3B+ to control my rig IC-7300 setup is way behind your faboulous setup, and one day I hope can make it better. My setup is plain and very basic. I set my RPi to connect either to my broadband P router or to my Android smartphone in hotspot mode. When outside my base, I enabled hotspot on my smartphone, and RPi will automatically connected to Internet to set it's time/date . If I unable to get proper data coverage, I use GPS app tu check the correct time and location, and set it up manually or by using scripts. I also do not use GUI/VNC connectivity to the RPi. I only use SSH with Android app called 'termux'. I can find the RPi address when connected to smartphone's hotspot, using this command. $ arp -an To control IC-7300, I use hamlib's rigctl command, and my own custom made scripts., which I able to control or set most of the IC-7300's features and settings. With Bluetooth keyboard connectted to the smartphone, I can operate my rig very quick and efficient. I also can send the audio from the rig to my smartphone, through RPi. One day, I hope can bring out my simple setup portable outside my base. :) I have 7Ah 12V small bettery pack, and USB power bank, which is enough to operate the rig during blackout.. :) Thank you very much for sharing your valueable information, and good luck.

I am currently setting up a raspberry pi very similarly to yours... I also opted for the Sabrent sound card interface with a CAT cable. I have not been able to connect to the radio and control it using flrig on the pi. Was there something special you had to do to get it to connect properly with your radio? I'm on a Yaesu 857D, so I assume its similar to yours. Thank you for your channel! Your expertise and experience been exactly the help I needed for getting my portable station up and running!
@OH8STN
@OH8STN 4 года назад
Hi Matthew, Sarah. All I had to do was select the correct cat control port for the rig. You can use the command "lsusb" to list all of the usb devices connected to your raspberry pi. Once you find it then the list, it's easy to select the correct one in flrig. I don't use any type of serial to USB converters or anything like that so I can't help if that's what you're using. Also make sure that you're using an ftdi chipset for your cat control interface. I hope this helps

Came across this video and very interesting, always been interested in prepping and communication has been something to think of. Being new to this: wouldn't a Raspberry Pi zero w be better? Takes up less space and draws less power, unless you want the extra processing power but how much multi process applications are you running? The Zero W can up run off of a power bank if need be and the W version has built in WiFi card
@OH8STN
@OH8STN 4 года назад
The zero is awesome for a lots of projects, but it lacks the processing power for decoding data communications, plys running the UI, vnc server, access point, ... I was hoping for a more powerful 0 which could do these things but the 3 B+ and the 4B where our only options. Awesome comment. We will eventually get to the zero on this channel :-)
@christopherlouw8325
@christopherlouw8325 4 года назад
@@OH8STN that would be awesome to see. The more processes it has to do the power it draws, what if you could share the load with the Zero? Also i was wondering in a setup like yours, what about a radio signal tracker? Like the way they track endangered animals. Just a way to get a heads up if someone else is close by

Hi Karen. Thanks for the comment question and kindness. I didn't mention it in the video but the point of the field test in Lapland, was preparation for winter field day. For Winter Field Day 2020, I'll deploy with the ft-891. The 891 is my default system for critical Communications. The 817nd is simply my prototyping platform. Anyway thanks for reminding me. I'll have to write a blog post about that tomorrow. 73 Julian oh8stn

@@kareneighth6045 the miniprosc plays extremely well with linux. I only removed it from field work, for added portability. I think I'll do a video setting up that interface with the Raspberry Pi. Others have already asked for that, and it's already in the works. Would that help?

Can you make it all in one waterproof box pre-wired? Perhaps affix the tablet to the lid of the case and the radio in the bottom? Then it would be self contained.
@OH8STN
@OH8STN 4 года назад
Definitely. In fact one of my buddies just published a video on exactly that topic. I thought about doing this myself, but I can't even consider starting until I have the prototyping done on the 891.. There's also the question of the power supply. Sometimes I want to take a big solar generator, sometimes I would only like to take a battery that lasts a day. So I need to come up with a modular way of achieving that. Here's my buddies video though. Let him know where you found it. It's definitely worth watching. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-diEEZVrVr8M.html

Now this is something I REALLY want to do. But....for an "off grid" setup....isn't a constant communication with GPS satellites/towers still using a literal grid?
@OH8STN
@OH8STN 4 года назад
GPS is only there as a backup for the time. Remember I already have a real time clock on the system. Also the GPS doesn't use any Towers, just satellites. Maybe I have to make another video to show how the third backup system works if the real time clock fails, the GPS fails there's also a third way using our off grid Communications. Anyway go for it! These types of systems are fun to put together, and amazing learning 👍👍👍
