ALL was fine until I tried SSB TX. PTT will not go into TX, CW keys up just fine. I went directly to 1/8 input socket and tried grounding PTT there and still no luck. Tim W4YN

Hi David:You might also want to join our site, too. (/g/SoftwareControlledHamRadio) There is a boatload of information there plus a lot of stuff in the Wiki and Files sections that

I can control output power. Am not near my T41 so can’t test voltages dave, n3ds

Ok so the software wasn’t there to adjust the TX attenuator. How the heck did Al calibrate the output power then? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ

When RX_BPF is LOW/FALSE/0, S21 between J23 and J18 (assuming receive is bridged to transmit in the TR switch) should be low, meaning less than -45 dB. That's what is shown in the plot on the right.

*** So - you did this measurement with RX_BPF_SEL = False, right? -Jerry, KF6VB

Music to my ears! Thanks Bill! David

I'm away from my radio at the moment. Can someone with a working radio confirm that this affects them too? Will take a look at the code tonight and see if I can find anything obvious.

Hi David! Welcome aboard! I shipped your boards today so you can get started in about 3 days! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big

Hi everyone. Just getting started with this amazing group and I wanted to write a quick note of introduction. I have long been a kit builder and tinkerer with electronics.? My first real success was

Good question… the TX attenuator should work the same way… so either there is a bug in the software… or there is a problem with the MCP23017. Since the RX side works I think its probably a bug

V12.6 RF board. 'Menu/RF Set/RF in Atten' works fine, I get the appropriate 3.3v at pins 21 - 26 as adjustments are made. But 'RF Out Atten' doesn't work the same. I don't see any voltage on pins 1 -

The book has that and I believe that the web site also has instructions on installing the Arduino IDE, the TeensyDuino, and the necessary libraries. Jack, W8TEE

Yeah Jerry. Dave, W0DF

It wouldn't take much to make the software "standalone". That is - being able to distribute it as a binary/hex file instead of making everybody compile the source. I believe that all that would be

Oliver et al, I second the need for a step by step guide of what software to use, where and? to use it.? I am not a software person at all and in all honesty I don't know where to begin with the

Hi Jerry, I posted the measurement I used to prove that U8 was bad here: /g/SoftwareControlledHamRadio/message/33289 Cheers, Oliver KI3P

At some point I will redo all the headers and pins again with new Tweeny and Hat. The last one I built I dispensed with the sockets and just soldered it all to the pins and the main board. As long as
