KBPF3A for K3

Does the KBPF3A work with the K3 as well as the K3S? I'm interested in
472KHz & 137KHz so am planning to order a KSYN3AUPG for my K3. Sounds like
getting usable sensitivity below 300 KHz requires different filters. Not
clear to me whether the KBPF3A works with the K3. Can someone clear this
up for me please?

Re: KBPF3A for K3

Yes, it does. You'll need to do a minor mod on your main/sub RXs to
decrease noise as well, parts kit for that mod should be available real
soon now, I hope ;)

My hope too, Ross. Sounds like a pretty easy
mod--except perhaps for the R&R of the boards
themselves.

The KBPF3A will work equally well in the K3, assuming the K3 has the added electrolytic capacitor across the 9 V regulator. That is the subject of an upcoming modification note.

Re: KBPF3A for K3

Let's hope that mod note isn't too far away...

Most of us can't wait to open up the RX on our K3's that sport the new
synth's.

The synth upgrade is an absolute doddle, my K3 got its "post Dayton"
upgrade today.

I'm already hearing aircraft NDB beacons at 300kHz across the country, it's
nice to explore this part of the spectrum.
