Kyle, et al,
Thanks for the quick responses. OK, it looks like the KBPF3 turns the
K3 into a general coverage receiver without having to order the
SubReceiver option. That sounds like a reasonable option to have to
allow listening to the CB/FRS bands :-)
My concern about the mounting location is the affect of the KBPF3
circuit board with similar tuned circuits in such close proximity to
the ham band tuned circuits. The affect may be subtle and only
detectable in unusually strong signal situations. I just do not want
to add something that could slightly reduce the K3's performance in the
ham bands. Instead, I can buy a good used separate 0.5 - 30 MHz
receiver for SWBC coverage for the same price as the KBPF3.
73,
Henry - K4TMC

Subject: Re: [Elecraft] K3 KBPF3 Benefits without SubReceiver?
... what benefit would it be to get
the KBPF3 General Coverage RX Filter Module? ... will this impact
the
performance while in the ham bands?
The KBPF3 is switched into the signal path instead of the ham-band
bandpass filters when you tune the K3 outside the ham bands. When you
are tuned inside the ham bands, it is bypassed and the standard
ham-band
filters are used.
There is no practical degradation of ham-band performance, and greatly
enhanced reception when outside the ham bands.
I use mine regularly!
Merry Christmas,
Lyle kK7P
