[Milsurplus] Mil HF rigs not NTIA compliant

[Peter Gottlieb]

Does anybody know why most military rigs are spec'd at 1 PPM frequency 
accuracy while NTIA compliance requires 0.66 PPM ?

I would like to use mil surplus (and very rugged and reliable) equipment for 
CAP etc. but am prohibited due to this non-compliance.

Side note:  I have yet to find a rig that wasn't significantly better than 
that 1 PPM spec, but nevertheless, NTIA compliance is based on radio specs, 
not performance.
