[Elecraft] P3 Manual Calibration procedure question

[Alan Bloom]

There is a small variation in IF output level from the K3 for signals
that are within the passband of the K3 crystal filter.  (The crystal
filter is after the IF OUT tap-off point but the input impedance of some
crystal filters can load down the signal level a little.)  De-tuning the
calibration signal avoids the error.
