As to frequency tolerances, I have no idea. The commercial SSB tolerances
used to be around 20Hz. I don't know what it is now. There isn't anything
specified in the NRPM as to tolerances and I would assume the FCC is
accepting whatever the precision of the current bunch of Japanese radios
type approved are at present. I would not press this issue as we are likely
to end up on the short end of the stick in some technical brawl as to "what"
the tolerances "should be", in all probability by "non technical" FCC types!
My brain tells me to "Let the sleeping dog lie!" in this case.

I am wondering what restrictions are placed on frequency accuracy?
Would simple QRP rigs like the Sierra or maybe a modified K1 be
suitable for operation on the 60 meter band? We are probably talking
about less th at 200 Hz. deviation from the specified center frequency.
Also, I don't think that the FCC engineers have randomly monitored any
ham frequencies for at least two decades. We are now "self policing".
