Yes, I've been going through that battle for several months with one particular MICOR 75-Watt repeater transmitter that I'm trying to move down to the 442 MHz range. I've retuned the exciter (VHF) output filter, and the UHF filter where you remove the soldered-on cover and then use the hex wrenches to adjust the tuning (the four coils always seem to be epoxied or superglued - most of them will break loose, but there's usually one or two that just won't go even after using acetone to loosen up the glue, and the hex wrench then just strips out the detents.) I retuned the internal circulator. Lots of spurs - I've tried different exciters, different filters, different ICM-rebuilt channel elements, PA Decks (2-watt, 12-watt and 75-watt versions) and PA control boards. Still lots of spurs when I crank the power up. Hopefully, I'll tackle it again before too long and go through everything again, try to find the right combination. But the receiver sure does work great, especially with the Angle Linear Preamp ahead of it!
