[App_rpt-users] Mastr II and URI low TX audio

[Corey Dean]

That is strange. I have never had a problem with either type of exciter on a master II.  I will be interested in what you find out.

Hello David,

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.

Bob,

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