Hi Arnie,
Your search would have taken much longer than reasonable. There are many thousands of posts here and much 'subject creep'.
If you can believe it, I was encouraged to leave a group (kicked out) because somebody took offense to that signature line. I miss them so much that I forgot about it until your comment :)

Re: TSW Firmware for ourTeensy 4.1 Raduino Kit
Thanks Jim. Just thought I would ask. I have been working with a STM32 Black Pill based decoder and use it for a belt and suspenders approach to CW. I have my 30WPM certificate from ARRL and find that even though I can copy that, I sometimes have trouble REMEMBERING what I copied. The combined aural and visual input helps and saves paper and writer's cramp.
Again, thanks for your work on this platform and for sharing it with us who are less skilled in the programming arts and sciences.

Hello,
You should also pay attention in Kicad the pin numbering is upside down.?In theory the nano should be mounted side welds to avoid noise.?So actually make sure the pin.

Re: TSW Firmware for ourTeensy 4.1 Raduino Kit
Hi Arnie, Sorry, but that¡¯s a no on the CW decoder. ?They take almost perfect conditions and really narrow IF bandwidth to even come close to what we consider enough accuracy. ?The uBITX is a poor platform for that with it¡¯s pretty wide crystal filter.
Besides, we want to promote people actually learning to copy CW. ?The human brain, once properly trained is FAR more accurate under poor conditions at decoding CW anyway. ?We don¡¯t want people blaming us for incorrectly copied callsigns that happens frequently with decoder programs. ?Even a tiny static burst will cause errors.

Re: Ubitx v4 transmitting moves pll on 10m
Well I might expect this with my efhw but not the triband yagi. But I get it, this effect needs a transmission line, nothing inside the rig is long enough to do exactly this. Perhaps the frequency spacing between spots where this happens relates to electrical length of the coax. Of course my other 2 ssb rigs don't do this so ubitx is a great educational tool. Thanks for thinking with me.?

Hola Peter,
Indeed, there is a noise. It is produced by the MISO / MOSI signals from the TFT display. Occurs when refresh data is sent to the screen.
?
In the case of the Raduino32, the Smeter signal is continuously refreshed, every second with the clock update and when the frequency is modified. In the original Raduino it is also heard, but since Smeter does not exist, it is less noticeable.
?
In my equipment it is only audible when there is no antenna connected and it is not audible when there is noise or signal even if it is weak. When an antenna is connected it is inaudible.
?
I know that doesn't totally solve the problem, but it is the best I have been able to achieve.

Re: Ubitx v4 transmitting moves pll on 10m
I've had a similar issue on my different BitX rigs from time to time and the answer usually lies with adding a stub, improving grounding near the rig, using an antenna tuner for more isolation, or even adding a simple RF choke by coiling 6-8 turns of coax. The most recent was with a popular EFHW portable antenna that was a 1:1 (or very close) match, but on 40m SSB, would sometimes send the rig into the menu. Adding about 10ft of counterpoise at the antenna fixed that one.

Sorry peeps, but we were testing out Sasi's subscription to the bitx20 list. We are bringing him in another group moderator. More about this in another email.

Re: Ubitx v4 transmitting moves pll on 10m
This is due to CMC... Use good choke
I can't think how to search for any prior hits. Only on 10m ssb, just on a few frequencies, I call a station. He hears me but when I transmit again the menu comes up for a band change, and the rig had jumped off frequency. And then it happens again when I try again. Using a 2 element yagi well matched also with a feedpoint balun, so I suspect RF inside the case is getting into raduino. Anyone else experience this? Strange it doesn't happen on lower bands. Maybe I need to clean up the wiring. Anyway nice to make a few cqww contacts today on 10m where things were okay, on most frequencies.?

Hi Ramon,
I have mine up and running but I am getting quite a lot of "chop" on the audio from the display, obviously because it is refreshing something on the screen, if I go into one of the config screens it mostly stops. Did you encounter this problem at all during your testing and if so what did you do to resolve it ?
Thanks!
Best regards, Peter.

Hi Max,
The PTT is the "TX" button. ?  ?
Regarding audio, I have developed an independent system that allows two-way audio sending and receiving. The system consists on the radio side of an ESP32, an I2S audio encoder and decoder:   It is connected to some terminals provided on the Raduino32 v6 board: Vol-H, Mic. The remote side consists of a LyraT board, which includes an ESP32 and codecs:? You can see the code for the server and the client here::? The system works independently of the radio and I need to work on the integration a bit. ¸é²¹³¾¨®²Ô
