I think this is also a source of problem-the fact that both repeaters
are ham-grade, and brands known for being a bit 'loose'. Two local
repeaters had a similar problem, but one was a Spectrum and the other
was a Micor station. There was a natural 2A-B product between the two
(2X output 1 - ouput 2 equaled input 1, and 2X out 2 minus out 1 = in
2). The Micor had no problem at all, but the Spectrum suffered with
howling whenever both were up. No doubt in my mind that if the Spectrum
had been replaced with a Micor or MII, the problem would've gone away.
Instead, I think it got pulled for other reasons. Nothing has been on
that pair for years.
