Hans, You might find this interesting. The chap has implemented an SSB, FM and AM RX on a Raspberry Pi Pico which has a dual core ARM Cortex M0+ processor. https://github.com/dawsonjon/PicoRX He

I have parts for the Ult6imate 3s that I would like to assemble with the transmitter and receiver in the box.? is there any place that shows how this is done.? Yes I know "why: Because,? I have the

Slightly different story here. VDD is showing 20Ω to ground without the PS boards installed. I decided to apply about 2.5 V to the VDD pin to which PS Board #2 attaches. Current consumption was 250

Tnx Bojan. I took a look, but still confused because I want only 1 instance. So I am not asking for a second instance. I guess I can go to task manager and end an app., but I wondered if there were

Hi, perhaps this info can help you: https://gm4fvm.blogspot.com/2021/02/multiple-instances-of-wsjt-x-using-more.html I am using multiple instances in Win10 but each instance than uses different

It is 2.6.1 downloaded direct from repository

Getting the port talking on a RPi 5 is the easy bit Its /dev/ttyACM0 Make sure you put this in the PTT Method box too. However 1 the Transmit audio source remains enabled meaning that it is not

When I run FT8 and JS8 call, I often have to exit the program and go to a second instance to have the program run normally. Is there a setting in the programs to prevent this or in Windows?

Hi Colin, I did the same today and removed L202, same result as your measurement. I then removed L201 without any change, so at least it's not IC204 that causes the short, either. When I switched on

Hi @all, is a higher output the only effect? 73's DL6MEE

I think I found the problem. I disconnected the T401 transformer input from pin 9 IC402. Then I connected the input of transformer T401 to RX_IN through a capacitor. The receiver is

tnx for the info. But a factory reset and a downgrade to 025 (and an upgrade to 026) did not solve the problem. 73 Bernd

Hi Hans, I think it is great that you are sharing your results with me.? I have stolen the Teensy 3.2 from my radio.? They are no longer available since the parts shortages of a few years ago.?

Do you miss playing in the NHL, Mats?

Prior to changing parts, I'd do a factory reset and see if the situation changes. 73 Dick W4PID

Ron, thank you your replies. I'll have a try with your suggestions but waiting on a smaller soldering iron. Most of my soldering experience is with vintage radios with point-to-point wiring. 73 - Dan

Hans, The SSB progress is very exciting! And the floating point capability of the processor is a big deal. Software developers at my past job absolutely loved it for its elimination of burdensome

P.S. I forgot another thing I was going to mention. The two tone transmission is analogous to transmission of zero in a BPSK (Binary Phase Shift Keying) system such as PSK31. In PSK31 a zero

Hello Ron That would explain why your previously presented traces earlier in this topic have constant frequency (no 180-degree jump at the zero-amplitude transitions). Assuming you are using 4800

RX band switching is accomplished with the microcontroller and IC402. However, as others have noted, the issue is probably assembly-related. Check C401 and C403. Is this a pre-built unit or a kit?
