[BCVHFA] Noise on our Ms repeater. Can you help identify

[Ed Thornsburg]

Hey everyone,

We have a noise on our 2m repeater down here that they haven't been able to 
locate. Haven't found it on a scope yet and seems to be only on the output. 
It comes on when the repeater id's. From the way I understand it, most all 
the equipment has been swapped out trying to eliminate it. A former Motorola 
tech apparently tried 3 or 4 times and could not locate it on his scope. No 
one has heard it on the input yet. It has been found on 2 other local 
repeaters and the fire dept repeater some 10miles away.

We put a DCI 2m band pass filter on it with no success either. It did help 
with the intermod though.

The sound file I have is 6MB. If you would be interested in listening to see 
if you recognize it please let me know and I will send it to you. Maybe 
someone from the OKI interference group has run into a similar sound. I just 
sent the file to DCI in the hopes one of their technicians can help.

I'm just trying to help out in any way I can. The repeater is located on the 
hospital and is used for ARES/RACES.

Thanks for your help,
