[QUOTE="Terryl, post: 1049430, member: 369937"] What you guys need is a combination of a Hi-pass/Low-pass filter, but they would have to be very sharp. We used what was called a digital brick wall hi/low filter, the combination of the two filters would be very tight, the low-pass would let everything up to 138.5 MHz through, and the hi-pass would start at 136.5 MHz and everything above that, the overlap after the combination would be about 2 MHz wide. The big draw back was the $1200 price. [/QUOTE]
