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.

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.

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! 73, Gwen NG3P

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.

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.

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.

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.
@OH8STN

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.

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.

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.

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?
@OH8STN

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

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. 73 Julian oh8stn

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?

@@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

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?
@OH8STN

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?

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.

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.

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.
