RE: [Elecraft] K3 KBPF3 Benefits without SubReceiver?
I am thinking about what future options to order for my K3. I do not plan to get the KRX3 Subreceiver. So, what benefit would it be to get the KBPF3 General Coverage RX Filter Module? Since this mounts on the RF board over the ham band bandpass filters, will this impact the performance while in the ham bands? A KBPF3 can be mounted on either or both the main receiver and KRX3. It functions the same in each receiver and adds the band pass filters to cover the frequencies outside the Ham bands. The benefit is allowing reception outside the Ham bands. There is no performance impact in the Ham bands with the KBPF3 installed. It is out of the circuit and not used inside the Ham bands. 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

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!

Re: [Elecraft] K3 KBPF3 Benefits without SubReceiver?
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 -Original Message- From: Lyle Johnson [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Sent: Sat, 22 Dec 2007 10:17 pm 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?

When not after BC, it can serve as a band scope for K3. Benny OH9NB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K3 KBPF3 Benefits without SubReceiver?
It doesn't degrade the K3 performance in any way. The KBPF3 simply adds the right input circuits to maintain full sensitivity across the entire tuning range.
