[Elecraft] KX1 RX Sensitivity on 20M vs 30M, 40M

[Klaus Koppendorfer]

i did a lot of measurements due to low sensitivity on 20meter with
trackinggenerator and spectrumanalyser the real max peak of the 20meter
bandpass filter is at lower frequency (abt 13 MHz) if you align the
filter for "max" gain on 14 Mhz the peak ist abt 6db lower as on 13MHz i
did some changes at filter caps.... but there is a strong influence with
the other two filters (40, 30 meter) maybee elecraft has there a new
redesign with new filter values - just see with analyser the filter
curves..
