[Elecraft] Exact 5MHZ Channel Frequencies

[George, W5YR]

Three KHz, Bob, not 1.5 as you stated.

ALL of the occupied bandwidth of your transmitted signal must remain within
the assigned band limits. Thus, the closest you could operate to 14350 with
a perfect transmitter (occupied bandwidth is zero after 3 KHz above te
suppressed carrier frequency) would be 14347 KHz. Since real world rigs
can't match that theoretical pefection, the cautious amongst us would not
crowd the upper band edge closer than 4 to 5 KHz.

I think you just made a typo . . .

when the FCC specifies the upper end of the 20M band to be 14350 kHz, you
must set your dial frequency (suppressed carrier) to keep your signal within
the band. Your dial should never go higher than 1.5 kHz below 14300 kHz for
USB. Same principle.
