[Elecraft] Advantage of KBPF3 in K3?

[Wayne Burdick]

> What would be the advantage of adding KBPF3 to both the Main and the Sub? 

You can put the main and sub on different bands (when CONFIG:VFO IND = YES). So having a KBPF3 in the sub would let you use a ham band with the main RX/TX while using the sub RX to monitor an the AM broadcast band, a MARS channel, WWV at 2.5 MHz or 5 MHz, a favorite SWL station, etc.

Having KBPF3s in both receivers adds some versatility, including diversity mode, which is especially useful for lower-band DXing.
