Hello David,<br><br>I am guessing the mastr ii radios have a preamp on the mic to get the voltages up. This radio is a VHF High band with the PLL exciter. I did change out the PLL exciter thinking it was bad but I had the same result. I will find out on the GE list to see if anyone there had the same problem. I will report back here with results in case someone else wants to do the same thing. Thanks for the info.<br>

I haven't tried directly driving a MastrII TX with a URI. However, I do<br>
know that, depending on how the TX is configured, they may require<br>
substantial audio drive voltage to get sufficent deviation.<br>
