Re: T41-EP V12 Board Connections and Development of the VHF-UHF Board
Except that modules that have not been released yet are not part of the connection sheets. Ask though if you are interested. The big ones will be the Tuner, the 100W module, and the VHF-UHF module.

Re: Attenuator problem
To be clear: the software is there to control the output attenuator. There was a bug when trying to use the menu to do so, but this does not affect any of the calibration routines.

Latest FW PTT not working
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

Re: Attenuator problem
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

Re: U8 test
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.

Re: Attenuator problem
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.

Re: Attenuator problem
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

Attenuator problem
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

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
