We have a MSR2000 for our club repeater. Every so often on a weak signal we get a noise that sounds like...well you know when you go to the dentist and get your teeth cleaned. The little tube that they put in your mouth and sucks all the spit out. Welllll... that is on the tail of some signals, sometimes. (sorry for the gross analogy ;-) This only happens a few times a day and not often on a stronger signal. When the user unkeys, it will have the "sucking sound" for a second or sometimes a few seconds...then the squelch closes. The user has unkeyed...but the repeater stays keyed up with the noise. We know that there are some strong signals near by the input. Also.... with the input at 144.61... there is a DStar repeater with a input of 144.60 up the road by 30 miles or so. Also... we have pretty fair amount of APRS traffic in the area (digi about 8 miles away).
Ideas? Robert KD4YDC
