Nope. The Micor is a very "tight" radio - which is why it works so well as a mountaintop system. You will have to first get the local oscillator / multipler working on the new frequency to get good injection level, then tune the front end. >Second question is the manual I have describes the alignment procedure >using the Motorola test set only. Does anyone have test point >descriptions for use with general test equipment? (Scope, DMM, Counter) There is a schematic of the test set and the Micor cable on the repeater-builder web site. I remember someone making up a list for the Motrac/Motran a while ago (i.e. receiver metering position #6 is from this pin to ground with a 50ua meter) but I can't find it right now - and besides it would need updating for the Micor. >Any help would be greatly appreciated. Honestly, I'd drop a few dollars or so on a Micor test set from eBay and do it right... look at the current ebay auction 280056006729 - or a similar one - it was made to bolt into a Micor station. I've seen those test sets go for as low as $8 (without the microphone) plus shipping. Note that the mic is the one with the older Motrac/Motran/Mocom plug, not a Micor plug. >Thanks No prob, that's what this repeater-builder group is for. Mike WA6ILQ >N3GH >George >(W3BD repeater)
