If XIT and SPLIT are off, the K3's CW transmit frequency is the
displayed VFO frequency.
The users desired CW pitch frequency is set with the K3's PITCH setting.
If the received CW pitch frequency matches the PITCH setting, then the
VFO will indicate the other stations transmitted frequency.
NOTE: Switching between the K3's CW and CW-REV (ALT button) will result
with no pitch change if the receiver VFO frequency display is set to the
other station's transmit frequency.
Test: tune to WWV at 10.000.000 MHz, CW mode, 50Hz BW. If the K3 is
aligned, switching between CW and CW-REV will result with no pitch
frequency change. (My K3 requires a setting of 10.000.002 to achieve the
no pitch change condition, indicating that my K3's frequency alignment
is 1Hz off.)
To comply with the 60M FCC statement "For CW emissions (emission
designator 150HA1A), the carrier frequency is set to the center
frequency." with a K3, set SPLIT and XIT off and set the VFO to 5332,
5348, 5358, 5373, or 5405 kHz. Assuming the other station is complying
with the same rule, on the K3 with RIT off, the received pitch frequency
will be the K3's PITCH setting.
The received pitch frequency is fully the operator's discretion by
adjusting the receiver BFO frequency offset setting. For the K3, with
the PITCH setting.
