Dave,
Since SW Broadcast signals are subject to fading, I would suggest you
add the KBPF3 to both the main and the subRX to give you the capability
of diversity reception. If you only want to purchase one, I suggest
that putting it in the main RX would make operation more straightforward
(just turn off the subRX).

Hi All,
This month I am celebrating my fifth anniversary with my K3. It has
performed flawlessly over this time …without a hiccup. My K3 was
purchased without the KBPF3 option in 2008.
Like many of you, I started my radio adventures in 1962 at the age of
12 as an avid SWL. I recently have become interested in SWL'ing once
again and though international broadcasting is not as it once was, I
find cruising these HF bands in Rx mode intriguing (probably my
attempt to regain an aspect of my youth at my now advancing age).
After looking at the vintage general coverage radios available on eBay
etc., looking specifically for an SX-100 that I once owned 42 years
ago (or an SX-88....in my dreams) most seem either overpriced or in
questionable condition , I decided to try listening on the K3 in
several of the international broadcast bands that are near hams bands.
Boy was I pleasantly surprised. Using the 6 KHz AM filter in my K3, I
was rewarded with a great general coverage Rx capability and really
nice audio.
So I am seriously considering ordering the KBPF3 option to install in
my K3. Here are my questions:
--Which receiver is it preferable to install the KBPF3 into; the main
Rx or the sub Rx or does it matter? I do not want to degrade the main
receiver performance in the ham bands even slightly. And while l
strongly suspect it does not matter at all, I wanted to ask opinions
on this reflector first so I can install the thing only.... once.
Also, do folks using the KBPF3 option prefer to use it with the 6 KHz
AM roofing filter or the 13 KHz FM roofing filter on SWL AM receive?
Any comments here would be appreciated.
I think this was mentioned a few years back but I’ll chime in again
anyway.
Elecraft could corner the general coverage receiver market by offering
an Rx version of the K3 (KR3?) targeting SWLs and a like. Once word
got out, I suspect that they they would dominate that market slice as
they are now doing with the ham market with the K3 and KX3.
Thanks for any thoughts or suggestions.
