Sorry, I should have provided more info. The repeater is a Vertex Standard on a frequency of 145.230 mhz out, 144.630 mhz in. We have moved the repeater since the photographs displayed on the web site. We're now using a Antenna Specialist 711 ( I hope I have that model number right), brand new, and about 140 feet of Andrews Hardline. I too think it's intermod, and have been entertaining the idea that there could be a dirty pager around here somewhere. We had the can's tuned by a professional ( if you go to our links page, click on T & W- they are also our landlord. Great folks!) I also have heard this noise ( I wish I could be more accurate with it. Perhaps I'll record it the next time it starts and put a link up here so you can hear it) on two UHF ham repeaters also.
