Just to add, I am thinking about replacing my bottom stack thunk from a socket thunk to a tty thunk to talk to/from the radio. If only I can intercede in the digital traffic flow...SDR I think. So I will have to learn a lot in order to program my UV-5R with Chirp to enable this. I will be visiting you all again in the future. I will work to stay on topic. I apologize for the divergence! An impedence mismatch.
Wish my luck on my Technician and General license exams tomorrow, please!
