Not really awake yet, but if one replaced the PK232's RADIO switch with
a relay & drove that with TR like conventional mode SO2R switching, couldn't
the button-pushing could be avoided?

On the other hand, the button-pushing is about the only way to keep
the RADIO switch from going flaky over time (PK232's input is high-Z &
it doesn't take much yuck on the switch contacts to impede things - the
extra wiping can really help).

Next workaround goal: TAIL END KEY.
