[chirp_users] Download From Radio under Ubuntu 20.04 error

[Robert Withers]

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!

Kindly,
Robert
