The other comments regarding the control line is a good one but allow me to pass on an experience I had in converting a mid-split UHF Micor station (C64RCB) to the ham band. Specifically, it needed to be moved *exactly* 10 Mhz down (it was on 451.875/456/875 and I was moving it to 441.875/446.875). Pure coincidence but there you go...
The receiver was no sweat - it tuned to 446 painlessly. The transmitter was another story, perhaps because it was being moved so low. What I found was that the exciter was no biggie, as it tuned down easily enough (although I did parallel a 1 pf cap across 2 or 3 coils to center them in their range a bit better than they would without the new caps). Of course, the exciter makes power on VHF and is later tripled. But you can hear it just fine for quite a distance on its ultimate UHF channel. I followed the directions on the repeater builder webpage regarding tuning the SECOND bandpass assembly and the circulator but still couldn't get *any* power out of the PA. What I found I needed to also do was retune the FIRST bandpass filter assembly - the one between the exciter and the tripler stages. Once I did that, there was no problem at all in the xmtr making power. FWIW.... Ken At 09:34 AM 6/2/2004 -0400, you wrote: >I have a problem.
