I'm not advocating V7A's for link service or anything but they are available cheap on the used market because many of them have failing displays which cost more to repair than the radio's worth.You can pull a "cos" out of them that follows PL by tapping the rx mute transistors for each speaker jack, program one receiver for spkr 1 and the other receiver for spkr 2. The rx mute transistors are surface mount LM3909's. Schematics are available on the web. Also you must leave the two volume controls cracked slightly or else the rx doesn't unmuteStevekf6fkk----- Original Message -----From: Mathew QuaifeSent: Wednesday, May 11, 2005 6:32 PMSubject: Re: [Repeater-Builder] Re: I need to take 5 volts to 8 volts, and one have a schematicThat was a good point out, never gave that a thought, so now I will just build 4 cor circuits to make them work, that will be easier than trying to make 5 volts jump to 8, can just make a simple 10 or 8 volt COR circuit.

I agree, you way sounds better, but these are here, and at $200.00 a piece,
for two receiver's in one box, works out ok for me.
<---Oh.. also be advised that the packet jack signals only work for the
currently selected band. In other words, you do not have simultaneous
access to both rcvrs/xmtrs that way.
