The version on GitHub should be able to set the TX attenuation now -- can't test it myself unfortunately.

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.

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 in the code. Oliver will know.

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 - 6 as adjustments are made. What am I missing?
