Hello from Italy, the 10m (39.6 MHz) crystal of my T4XC is faulty, I'm 99% sure because I tried it also on the R4C with no success. I think that I can't find any original or already done replacement, so I need to know the specification of the crystal for a custom cut. Anyone can tell me the data that I need? Thanks a lot! Ciao, 73 and happy new year Guido, ik2bcp / iu2r / ab9dg
