Let's get real: 1,000,000 Hz (a MHz). 1 per cent is 0.01 of that, or 10kHz 0.1 per cent is 0.001 of that or 1,000 Hz 0.01 per cent is 0.0001 of 1 MHz or 100 Hz And 0.001 per cent is the debated 10 Hz
Stuart, It's not the acuracy here by displaying to a 1 hertz value that's real important. It's the ability to adjust the frequency in 1 hertz increments. I have a mode I call SAM for sync AM that is

I'd like to throw my opinion in on this as well, but first a little background on me: I am a ham, but the time I spend in HF is spent listening. I primarily listen to utility/military stations, but I
Hi all, My fourty something year old ears (which are better than my memory of how old I am) can definitely tell the difference between a 10 Hz beat and a 1 Hz beat. Does it matter? Probably not for C

Anyone who took high-school physics should be able to give a learned discourse on the subject, especially if he or she ever had an answer overwritten with "SIG FIGS" in red ink! :-) -- Eric F. Richar
If the errorenous idea exists that frequency accuracy is perceived as the solution to selective fading problems while receiving AM in SSB mode, then one must realize that no amount of dial frequency

No, but ECSS, as using SSB to receive AM signals is called, is sometimes your only option when you don't have a true synchronous AM -- one that phase-locks with the carrier -- available. Also, many
Dennis, When selective fading causes the carrier to drop far below the amplitude of the sidebands, reinserting a carrier with a BFO is a way to improve detection of the AM signal. This is not erroneo

turn the knob until I hear what I want to hear. On the other hand, some folks set the frequency with the KNOB and then complain that other stations don't sound correct. Isn't this like putting the c
OH, Ok Carl, I missed the comments about the other mode of operation you were interested in. Interesting mode. I wonder as someone did if any capability for closer control of the BFO is possible in u
Well, perhaps the theory doesn't support careful zero beating and ssb as a help for selective fading but, my experience with a Jupiter and N4PY software does. Aerodynamic theory, at one point, said b
