When I ordered my K3 and accessories I did not order the KBPF3 because I thot that was to add general coverage receive.... Now, I am thinking it is a bandpass filter to filter OUT non-ham band signals. That I need, so another order if my latter idea is correct. What is the function of the KBPF3????????? Do u need one for both main and sub receivers? 73Charles [EMAIL PROTECTED] > From: [EMAIL PROTECTED]> To: [EMAIL PROTECTED]; [EMAIL PROTECTED]> Subject: RE: [Elecraft] Filter question> Date: Mon, 18 Feb 2008 15:04:44 -0800> CC: elecraft@mailman.qth.net> > Does the KBPF3 go into the RX module or the main board module?
