Mike:
It's all coming back to me now.. Your first approach is exactly how I
monitored my CW note when transmitting. I had an old rock-bound Heath Kit
DX35 transmitter, and a Lafayette receiver whose model number I forget, and
made many CW qsos that way back in the day.
Thanks for jogging my memory here.
