Adding this little circuit to my second, V2 sbitx. ? as luck would have it the first Opto coupler board was defective. Had to build a 2nd one — but works well now I learned here how to get the

Hello, Unfortunatly the pinout is different 73 Patrick

Depends on what else is running..

The Radxa is hands down a more performant SBC. Unfortunately the GPIO arrangement isn’t 1:1 so that may be a challenge without some re-engineering.

It is fascinating watching hams solve problems/improve a radio that hasn't even shipped yet, let alone demonstrate problems that need addressing. A quick search leads me to believe that FreeDV works

Are we discussing about a change in the digital section of the project? I feel it's a good idea. If any board that adheres to the RPi IO connector can be tried. I guess the efforts can also be used

Hello, we don't even know when it will start shipping, and we all want to rewrite the design from scratch. I'm in, too. Do you think it would be possible to change the raspberry for another more

I have now switched from USB to DIGI and there is no difference, I use the previous settings. I read the output power on an external Daiwa CN-801Type H meter, because the built-in meter cannot be

Wojtek, I haven't been doing much radio lately and it didn't show up, but there must have been some modification, because so far the wsjt-x and jtdx transmit slider didn't affect the transmit power. I

Thanks for posting a solution! Now the next time we b?rk one, we can find this. -- -- J R Parrick (K0TBS). *Si vis pacem, para bellum!*. [K?TBS website](https://k0tbs.net)

I run WSJTx on my DE which has the hardware upgrades. I used to just leave the slider up all the way and control the power out with the Drive Setting. But I recently upgraded and updated to the newest

I have this problem as well. Using either wstjx or fldigi, I get a max of ~3 W out(*) with the power sliders at maximum. I am no longer alone in the universe. (*) DRIVE set to 63 to get 10 W out on

I set the mode to USB in the sbitx application and the maximum power is still 2W. The slider in wsjtx still controlls the power. 73, Wojtek

Wojtek, Set it to USB and you can set the output power with the Drive value. The wsjtx slider does not work with sbitx, the Drive is the determining factor. -- Gyula HA3HZ

Hi, Due to the problems with non-standard callsigns, I have decided to use wsjtx. I have updated sbitx with the `update` script. I start it via VNC. * I installed tigervnc on my sBitx * I log in to

Yes, it can be quite confusing. It's also possible that an errant hot wire from a bench psu touched somewhere. I had to step back from this one for a while, because I was beginning to get frustrated

Sounds like another case where something is screwy. I don’t think you could blow D7 unless you had reverse polarity power. so there may be a mislabeling or a screw circuit board here. Or maybe

Mike, D7 is for reverse polarity protection.? It should not blow unless the power is connected wrong. I had trouble adjusting the bias on my DE sbitx.? The TR switching was not working correctly,
