Thanks Eric! Maybe I can trade it to someone local who wants one. I'll have to see if I have the other crystal somewhere, and see if I can turn it on. With no manual, it is almost impossible to know where to start.
I had a Mocom 70 also, but I think it got tossed before we moved. I'll have to look for the Mocom 70. If anyone here desperately needs some parts from it, let me know. 73, KD6AAJ --- On Sun, 10/26/08, Eric Lemmon <[EMAIL PROTECTED]> wrote: > From: Eric Lemmon <[EMAIL PROTECTED]> > Subject: RE: [Repeater-Builder] seeking executive mobile radio information > To: Repeater-Builder@yahoogroups.com > Date: Sunday, October 26, 2008, 9:44 AM > That combination number is for a Mastr Progress Line > Executive Series mobile > radio, which was offered in three low-band splits: A (25-33 > MHz), B (33-42 > MHz), and C (42-54 MHz).
