Re: zBitx alternative board...
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

zBitx alternative board...
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: sBitx v3 - original application gives high power, wsjtx up to 2W only
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

sBitx v3 - original application gives high power, wsjtx up to 2W only
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

Re: reviving my sbitx v3
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

Re: reviving my sbitx v3
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

Re: reviving my sbitx v3
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,

Re: reviving my sbitx v3
So, everything is still switching, but...when I was attempting to adjust the bias, which was about 800mA in receive, and about 1.2A with PTT engaged, in USB, 40m drive at 1 mic at 0. When I began to

Re: Chirpy audio in ubitx6.1 #bfo #ubitxv6 #v6
Found a cure for this defect. I have disabled existing LM386 audio amp and used TDA2822 amp module. I took audio input from IC socket pin 3 without any surgery. Now audio is good. The only issue is

Re: reviving my sbitx v3
Mike, As Gordon points out, there is most likely a problem with the receiver TR switch.? As with the transmitter switching, verify the operation of Q28. You can also try removing the RF from the

Re: reviving my sbitx v3
They should be back biased by the high-voltage supply. Either it’s not working or there might be a problem around Q 28, haul out the voltmeter meter and start looking at voltages in receive and in
