Over twenty years ago, our "repeater" receiver, a Spec Comm, finally gave up the ghost after a year or so. Not knowing any better, I took my trusty old IC-22A crystal controlled mobile rig, found the proper signals to interface the receiver portion with the Spec Comm transmitter, and placed it in service, figuring it would do for a month or so until we bought another "repeater" receiver. Well, you may have guessed the result, the '22A lasted many years and only after a lightening bolt laid it to rest did we repleace it.

Simply placed one of the "garbage can" size filters on the input. Absolutely no intermod and better sensitivity than the normal MASTR II that had failed. At the same site I also use a TM-241 as a remote base controlled by an FC-1 with no problems. On the remote I have a notch filter tuned to the frequency of a 1/3 KW transmitter in the 152 MHz range. There are 28 transmitters at the site and within 300 yards there are another 30 transmitters on another tower. Bottom-line is they can be made to work in high RF environments but a receiver with good front-end filtering will work without the need for additional filtering.

Any help would be appreciated. Cory Lee KC5EWJ .
