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. 73, Sandy W5TVW -----Original Message----- From: Rick Dettinger Sent: Saturday, November 19, 2011 3:24 PM To: Sandy Cc: Mike Morrow ; [email protected] ; TETRODE List ; Old Tube Radios Subject: Re: [Elecraft] US 60 Meter Band Changes Approved by FCC - CW Issues 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". 73, Rick Dettinger K7MW On Nov 19, 2011, at 12:55 PM, Sandy wrote: > The CW signal must be radiated on the center frequency.
