Comments on this site, indicate the down side of trying to get the RX front end board to make it into the ham segment. They all say it won't make it to the frequency segment that is needed.
Other comments point to the PA output filter also not making it to the needed frequency segment.
Lastly, I still have not found any firm threads that indicate the ability to move the VCO so that it will work on the UHF ham segment.
Has anyone out there any new input on this topic of moving a UHF band 1 Spectra into the 440 ham band?

Not every Motorola Radio was *designed* to work in a nearby ham band, but many of them do. The R1 UHF Spectra is one of them, the RI MCX100 is another....
