[Elecraft] K3 VFO B Anomaly

[Robert Beard]

Good Morning List,

Just noticed, while tuning VFO A down through 4.800.0 MHz, I can hear a relay switching. 
I believe this is band pass filter switching on the KBPF3 board.

All well and good, except that VFO B jumps to 3.526.76 MHz at the switching point, regardless of any previous setting.

When tuning VFO A back up through 4.8 MHz., the relay switches and VFO B jumps to 5.300.00 MHz.

Anyone else seeing this curious behavior? (Or am I missing something....?)

K3 is s/n 1500 with 3.14/2.16/2.16 installed.

Best regards,
