Mark,
The CW key line is shown being pulled high with a 1k resistor to 5
volts. I loaded the code into an Arduino Uno and found the same
problem, but I didn't have the key line pulled high. If I touched the
key line with 5 Volts it whet to receive. By the way, I don't have
anything started yet, I am waiting for a PC board.
Good luck and thanks for keeping us informed as you go along.

Hi Team
I am seeing some problems in my tests today where I am not able to
switch between TX and RX all the time - sometimes I am "stuck" in TX.
I seem to be able to fix this problem by tying the CW_Key line "HIGH"
i.e. connecting it to 5V. I don't yet fully understand the code and
what is happening with CW as there is a key attached in the schematic
but the pin is defined as OUTPUT in the code? Also when I there is
nothing connected to the processor pin 5 it is OK, but when the
components around Q23 are connected the software immediately reports
it is in TX.
As is so often the case - it is sometimes difficult to understand
other peoples software.
Is anyone else seeing this problem?
Thoughts?
