[Motorola] MSR-2000

[Steve Tripp]

 I have an MSR-2000 on 440 and running quite nice with one exception. I find that the TX drifts more than I like. It moves +/-1 khz and is EXTREMELY critical to adjust. It moves khz's with minimal adjustment. I ordered Bomar xtals and installed them myself. After some aging, I noticed the drifting. I  bought another set of kxn-1088 and 1086 and had Bomar install and temp compensate. The same drifting occurred. 

Would International do a better job? Does anyone know where I can get the 2ppm elements. 

Thanks for any suggestions.
