[CALV-AUXCOMM] Dealing with Unlinked Repeaters

[W. Hackett]

Or we could ditch the Yaesu Junk and install some rock solid  Motorola,
Kenwood ,  or Icom repeaters.

just a thought for discussion.

  Good Ideas last night guys and a good test.  Thank you all for trying the
diffrent  work arounds .  Ham Radio at its best .

 I may not talk a lot , but I listen.
