[R-390] R-390 Break In Operation

[David Wise]

Assuming you also disconnect and ground the antenna input
to avoid frying the RF coil, sure.  I'm curious though:
why not use the standard break-in connection?  It does
exactly that, and mutes the audio line too.  It requires
a contact closure, which you can probably supply as easily
as the contact opening required for your proposal.
