Are you sure it isn't something caused by your service monitor? Have you tried a different one, or is there anything else common to all three radios?

Really??! I found and tested a third radio... same problem. To restate what the problem is: Micor mobile UHF T34... when running in the ham band transmit low / receive high they are spurring 910 kHz above the transmit freq. I don't know what would happen if the frequencies were reversed. 443.750T 448.750R spur at 444.660 444.000T 449.000R spur at 444.910 It's not a power supply problem. The spur is generated low level, not in the PA (it's somewhere before or at the exciter mixer, Q305). It's not the offset oscillator. No amount of tuning or de-tuning various stages has any affect on the spur. Paul N1BUG Yahoo! Groups Links Yahoo!
