Receive Sideband
Receive sideband calibration nulls (rejects) the
opposite-sideband image. This image is a weak
audible side-effect of very strong signals.
This calibration step is done at the factory
for KX3s shipped with the KXFL3 option at
time of purchase, whether factory assembled or
kit. It must be performed by the owner only if a
KXFL3 is purchased and installed later. Please
refer to the instruction sheet supplied with the
KXFL3 option.
