3.5999MHz QRSS QRG update

Reaching in my junk box, I could not find a 6.400MHz crystal :-( Yes, they can be ordered... however....

What I found instead is even nicer, a 9.600MHz crystal, together with a 6.000MHz one, even in one bag. The 9.600 xtal looks like I salvaged it once from something. I would not recall what, possibly some obsolete network gear.

I guess, the design of the 80m secondary frequency MEPT is hereby decided. Nice in this is, with actually using the difference, some drift cancels out.


  1. N4ESS has 7200 kHz crystals, divide by 2 and voila - 3600 kHz

  2. Perfect solution! By far too simple for my walnut :-))
