I found it easier to disable the AFC. If you don't... with a poor quality crytal in a not so stable (temp) room you'd often find your repeater quite aways below F-center in the cool morning and quite aways above F-center in the hot evenings. Being the owner of a "VFO Repeater" was not something to be proud of. T'was one of my first real cases of buying cheap crystals that became obvious real fast. Since I never wanted the afc action in the repeater conversions... I never bothered to change the diodes... I just disabled the AFC. > > [EMAIL PROTECTED] wrote: > > OK thanks - I'm trusting then also that I can do the same on > > UHF, order high-side injection crystals for my KXN1024A UHF > > Receiver channel element and leave the discriminator diodes > > as they are. Where I learned the gals at International Crystal know their stuff very well. If you call and specify the UHF Micor Mobile Crystal for a KXN-1024 with high side injection... they know what you want and how to make it with out 100 extra questions. Once you get the channel element done right... you need to be sure you follow the proper manual transmitter alignment instructions. A shortcut in the tx alignment steps can result in a very nasty transmitter. cheers, skipp
