[Repeater-Builder] Motorola MICOR Receiver VHF
Anthony, Check the PA tuning. The PA is feeding back on itself. We had this same problem on our SC Forestry VHF Micor a few years ago. The PA will drop power when this happens.

RE: [Repeater-Builder] MOTOROLA MICOR receiver VHF
Anthony, I've worked with a few micors and replacing the receiver is simply remove the old one, insert the new one and tune. For stand alone I prefer the micor receiver housing. Usually have to build a power supply for the receiver wants 9.6 and 13.8 volts. If you are connecting to unified chassis there is most often a connector on the card cage board for adding up to 2 receivers. It will take any band of Micor. Seems that Motorola stuck with its receiver accross most if not all of its Mocor line. The transmitters changed alot. One thing I have found for VHF most Micors were built for 150-160 MHz range due to commerical service needs in USA. Gov and Canada used 140-150. This often required mods to the helical. Simply replacing the 10-32 screw lugs with regular screws with head inside the helical made it tune down to 140 MHz range. Don't know what its skirts looked like, but did work well. 73, ron, n9ee/r Yahoo!

Re: [Repeater-Builder] MOTOROLA MICOR receiver VHF
Tell us more details of what you have on your mind of doing. Most of the different frequency band receiver boards for the micors are interchangeable. ie you could make a cross band repeater by using a vhf lo band receiver along with a vhf hi or uhf exciter and vice versa. As far as placing a receiver board in a separate box, as if you are going to use it as a remote receiver for remote control, etc, motorola has done this in most models of it's paging transmitters, and repeaters, by adding the shielded interface box and cabling, etc. Let us know more about what you want to do.
