Rafael - excellent! Thank You!??????????? N3SB

Hi Steve, It is totally possible to control the volumes separately, and I'm already using for some time like this. I pointed to you how to do it in a github issue, but I think you missed it. I post

Dave, The R-55/T60 was what I started with in 1965. Washed windows, cut grass, worked at an A&W for the money to buy it. Brings back good memories. Barry kk4vt

Just an update… I think I found the problem! I tried to install the old Sbitx version from the website in another SD card then I did the update… and it worked! Then I changed the OS locale to

Here's my theory. Unfortunately I'm not able to duplicate this problem on my DE. The digital to analog "output" side of the CODEC has two channels - since it's a Stereo CODEC. One side is used to

I should add to this search, that I'm also happy to consider a V.3 or V.4 board.? I have all of the stuff to bring them up to spec. Thanks.

I'm sorry, but I need to point out that my argument included options for spending the same, spending more, or spending less, and still ending up with a working sbitx radio.? The 'spend more' option

The amendment was made for the following reasons: Update sbitx_sound.c to fix sound bugs and reduce CPU load #69 The side effect appears to be undesirable. I also reverted to v3.01

To me it sounds like the RX audio is being opened up as the TX is coming on.? Just a burst of RX audio before being muted again. Perhaps a change in theRX/TX key timing? -- Mike WB5LLI

Hi, I did some measurements with the oscilloscope. No signal (just noise) on the AUDIO-MOD line, I tested it on the node between pin 2 of Q6 and R56. Does this test help? By the way, I connected a DSI

Ashhar, Unfortunately, he didn't win... I run wsjt-x in the background and <...> is visible just like on the sBitx v3.02 screen. -- Gyula HA3HZ

Further update… Pi4 now booting but very strange fault, I have no RX. The set produces noise as if it is receiving but only noise. Even more strange, sometimes after booting, it will receive ok! I

Gyula, The only way to actually find out what is going on is to run wsjtx in the background as well and sew which callsign went missing. Is this v3.02?

The problem with your argument is this: "Whatever the market will bear!" If the radio starts using the new processor, it won't be long before there is pressure to make all of the radios use the new

Actually the sbitx comes with Pi 4 2GB which is currently $45 list price, Pi Zero 2W with headers is $21, so switching would save $21. If you can get headers cheaply and do your own soldering, you

I get where you are going, but it's not as simple as that, IMO. We might as well ask: why pay attention to cars at all, when all you should want is a faster horse?? Horses can eat the local grasse

Today I was peacefully radioing in ft8 mode on 21 MHz when the image below appeared on my screen. Since I had done the same thing 10 minutes before, only then another station called at the same time,

Oh, I forgot to add that during TX I can correctly hear the signal through the speaker (CW and FT8), if that can be helpful to the diagnosis. L.

Ashhar, I was thinking about checking the signal "AUDIO-MOD" coming out from the WM8731 and following its path through Q6. What do you think? If I understand correctly, all the signals are generated
