[App_rpt-users] Noise Problem with URI

[Ken]

I would be curious to know what level you run the tx output at ?
?
I put an extra pot inside my exciter,?at the audio input, so that I could?run the txmixer (or whatever it is called) at around 500 - half of full scale.
?
I had a noise problem on the CTCSS input of the Hantronics, as well, when I added the separate PL signal later on.
.?
That is because?the Hamtronics CTCSS input?is *very* low level and high impedance. In that case, I just put a 47 ohm resistor at the exciter input.??The URI has no trouble driving into this low-Z and it killed that particular noise.

I get one more noise that I cannot figure out though ... at the end of a users transmission there is kind of a low-pitched "glug-glug" noise before the courtesy beep - seems like some sort of artifact similar to a previous version that would not play disconnect messages - but would still make some sort of noise...
