Barry,
I understand and thank you for your reply.
Your solution involves less writing :-)
I see David has already managed to try it.
ps.: if you want to delete the message you created that you consider to be incorrect, you can do so.

It works! Thank you so much for the help! You dont know how grateful I am. Hopefully someday there is a hardware solution that I can help you with somewhere... maybe... :)

Thank you again,

Barry,
I can't program, just trying to follow.
Am I correct in what you wrote?

The following lines from index.html cause the sync problem you mention:

Looks like I stumbled right out of the gate.

The first step in install.txt says to install WiringPi but the Pi 5 came with the 64 bit OS.

Even worse, it seems WiringPi is end-of-life ( ref: ).

I went to see I could get the code from the author's git site, but:

git.drogon.net is currently unavailable.

Please look for alternatives for wiringPi, etc.

(I really mean look for an alternative - as in use another GPIO library. also read the news on )

-Gordon

So, it really looks like the end of the road for WiringPi.

I could install a bunch of the 32 bit user mode stuff (in particular libc6) and see if I can build sbitx as a 32 bit app running on a 64 bit OS but I think the WiringPi part still probably won't work, because it appears WiringPi knows chipset-level details and it appears the source needs to be updated for Pi 5. I'm pretty sure Pi 5 is not register-level compatible with any of the earlier Pi devices.

I could be wrong, but as of right now it's not really worthwhile to proceed since the code is deprecated and is not available anyway. Maybe I'll feel differently later, who knows...

Hello all,

I have been investigating the problem with running FT8 from the GUI and have narrowed it down to this.? It works as it should IF YOU CALL CQ. That works great and I am able to complete QSOs just fine for the most part as long as the automated process runs it's course as it should.
The problem comes in when I ANSWER another op's CQ. Then it goes something like this, they call CQ, I reply, they acknowledge and send a signal report, I acknowledge and send one back. Then right after my cycle ends, during the time when my radio should be listening, the sBitx will send the reply again. Kind of like a sequence of AB AB AB BA BA BA BA... Once it reverses the order, it doesn't get resynced until you ESC out and start over, then the process will repeat this pattern every time.

Another small issue is that the F keys for sending macros is not working on the GUI for me at all. I can go to the original interface and get the macros to do things though. Since I can get the marcos to work in the original version I am going to try to learn how to use then to answer CQ calls.

I don't know how to code at this point so I am not help other than running down the problem. I am hoping that one of the most astute coders in here has already solved this in 5 seconds and I can fix it easily...fingers crossed.

Hope everyone has a wonderful day and I also hope someone can fix this easily.

Thank you for your time,

Dave,

Very impressive and ingenious getting that si5351 out!!! I am even more impressed that you were able to solder it back on with an iron! ?You must have very steady hands!

?A side note, waiting on a new spin of the Raspberry Pi Pico board. This one should have the correct triggering for an external amp or RF switch. Have one more change after that as I want to move the onboard s-meter diode detector to a SMT instead of TTH. That way I can just have JCLPCB place all the components except for the headers and JST connectors. Assuming that works, will propagate this change to the Teensy boards and call it done.

It's not clear if the "active cooler" prevents placing a hat on an RPi 4, but I suspect it does - though a GPIO extender may change that.

says:

Well, you can mount a HAT above the Active Cooler using a set of 16mm GPIO extenders. Inevitably there is some disruption to the air flow which will cause the Raspberry Pi to run hotter, but the Active Cooler is still able to handle extended stress tests without significant temperature rises.

RPi 5 boards should start shipping/be available in stores this coming week, Microcenter appears to be expecting them soon...

I took the magazine subscription offer, and got mine today.

Congratulations on overcoming obstacles and the successful repair.

But for reference: Scotch tape, or any insulating tape, can build up a very high charge when pulling it from the reel.? It's not wise to use it around any ESD sensitive components.

My problem is resolved. So, here is a brief report...

Mark Hatch (AJ6CU) kindly loaned me a working Raduino with a programmed Arduino Nano. That made my uBitxV6 functional.
My Nano also worked in his Raduino. Apparently, I had damaged my si5351a in the process of Nextion mod. (Perhaps lack of anti-static protection, or perhaps due to originally inserting the Nano with pins "upside down.")

In any case, I replaced the si5351a (I purchased a few at $2.32 each, at Mouser.com), and the radio works now, that my Raduino is repaired.

The si5351a replacement was accomplished without the proper soldering tools for that tiny surface mount component. It takes a steady hand. My method: Use two soldering irons, to heat pins on both sides of the old chip and lift it away. (Caution: The PC foil lands are small and delicate.) I cut a 1/8" wide,? 2" long strip of Scotch Tape, put the chip under the mid-point of the tape, positioned the IC leads on the lands (noting orientation dimple at pin 1), and secured the tape to the board. Then, I used a fine tipped iron to seat the IC leads into the solder already on the pads. I did one side, then the other. The IC shifted slightly (the tape stretched when warm), so on one side, the pins are not perfectly centered. I should have done one pin on one side, then one pin on the other, before doing all pins. But it works, and it's best to leave "well enough" alone.

Mark also sent samples of the Raduino boards which he has developed for other microprocessors, such as the Raspberry Pi Pico, and the Teensy 4.1, and also a Button Box board for use with KD8CEC external switch options. His boards appear to be very high quality. Learn more about them and his related firmware at ? (I'm sure he would be happy to discuss those options with you.)

To each of you who offered advice and suggestions for trouble-shooting my symptoms: Your help is very much appreciated. Thank you all.

The "active cooler" for the RPi 5 includes a heatsink as well as a fan, the "official" case for the RPi 5 includes a fan (much like the available fan accy that is available to add to the RPi 4 "official" case).

The problem is that the encoder isn't getting sampled often enough. It's a software design?issue.

Thanks for all the great insights! I'll keep them in mind going forward.

I was thinking it could be a software issue but was thinking of a totally different scenario. I was imagining (without doing any analysis) that it was a software problem, but one where the decoder was sending frequency change commands to the app faster than it could handle them. This could cause a big spike in resource usage (cpu, memory) that would take the device a while to recover from. In particular I see some times if I change frequency a lot in an exaggerated way, the app locks up.

The radio is quite usable as-is, and the lagging phenomena is not unique to this radio. I have been using linhpsdr software with Hermes Lite 2 on Raspberry Pi 4 and it too could get laggy. It's just interesting to me to try to understand the weak points and address them whenever possible.

More speed could help with FT8 decodes.

Probably will, but I haven't used FT8 enough on sbitx to understand its strengths and weaknesses.

I also ordered one from the PiShop us but no info on shipping yet. I ordered it with the case with active cooling but for sBITX you would need another solution.

I didn't understand that the case also came with a fan, so I ordered the case as well as the stand-alone "active cooler". I'm sure I'll find a way to use both of them.
