I noticed that later last night (2am) on the M1/M2.. While looking at the drive required for the PTT relay I noticed the RX signal (+12 volt supply to the LM386) is switched by the PTT; Has anyone tried adding a 3.3k resistor to pin 6 of the LM386 and ground?
At any rate I came across K3NG Nano Keyer, I'm changing my layout to use his code.??-- My 'Logic' normally stops around 10PM, that post was past my bedtime! Still waiting on my board.... My layout includes a TCXO for stability, +3 regulator instead of the nano 50ma source and voltage level shift for the Si5351, it does add a couple of dollars.?? ?
