make 1st gm 160 as transmitter and the 2nd as reciever and all work DPL the
problem is when i talk by the handheld ( gp360 ) the other one (gp360) receive

Hello Andy,
I would start by looking at the reference oscillator that the PLL uses
to lock on to. Is it running and is it on frequency?

Hi All,
Any one looking for a Mastr II key (Mobile or base/repeater) only needs to go
to the local lock smith (Not Home Depot or Lowes, they only copy)
The Smith can cut you a key from the book. It is a BF10a. (I have done it)

We have an NHRC-7 on our VHF Mastr2 tied to our UHF GR1225... Once the audio

The ARCOM controllers are very popular in the neck of the woods... But for a

The most common cause for desense is connections and not actually the
duplexer. Especially if there was no desense prior. First I would check the

configuration) put a meter right there where the hard-line comes
