K3 strange behavior

[Roger D Johnson]

Whilst searching for some RFI, I noticed my K3 has a sudden drop in gain
when tuning up past 3300 kHz. I have the KBPF3 installed but don't know
what frequencies the K3 switches from the normal filters to the KBPF3
filters.

73, Roger

Roger,

It could be switching from the 80 meter band to 160 meters at that point. Is it possible you have a different antenna (e.g., ANT 2 or RX ANT) selected for 160 m but nothing connected?
