[App_rpt-users] Noise Problem with URI and Voter Comment

I finally had time to try some things out, I was able to get rid of the noise by putting some resistance. Actually I put in a POT and set the RADIO TUNE TXVOICE just above mid range. Then I used the pot to adjust the deviation. I ended up with around 6k of resistance. When I have more time I will adjust the RADIO TUNE TXVOICE to mid point and do the same test.
Thanks to all!

>> Sorry guys I just realized when I was hitting reply, I was replying directly to the individual. I would guess proper etiquette would be to email the group. Or at least CC the group.
>> Thanks for all of the suggestions, I will try adding in a resistor or a voltage divider. I will have to check to see if I have a 1:1 transformer laying around. And yes the "RADIO TUNE TXVOICE" was on the far low side. I will also double check to see if the monitor is creating the noise by turning it off.
>> I thought the same thing (regarding local HT noise) and hooked up the audio input leads to the audio path and seen this (hopefully I can attach a picture). I also had someone off site confirm they heard the noise. I did not think about trying to figure out the frequency.
