[Elecraft] KPA500 - Rx Attenuation

[Rick Robinson]

Oooop's. I saw somewhere about AM band reception. It is the ATU
filters.Here is what I was thinking of....

"The KXAT3 antenna wide range tuner plugs into existing connectors inside
the KX3. The KXAT3 stores the
settings found for the best match at multiple points across each band,
allowing for quick frequency and band
changes. The KXAT3 also includes an automatically tuned filter for the AM
broadcast band that tracks the
VFO, improving image rejection for signals in the 0.3-1.0 MHz range."
