Rich, There is no direct relationship between the crystals and the caps for the 2.4 and 2.6 kHz bandwidth filters.
Sorry to hear about the attenuation - check the soldering and re-check the soldering of T1, T2, RFC1 and RFC2. 73, Don W3FPR > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Rich McCabe > Sent: Thursday, March 09, 2006 10:11 PM > To: [email protected] > Subject: Re: [Elecraft] K2 SSB > > > Well I dont know :) > > The manual they sent says revision D and January 2004. > > This manual shows installing CB and CN and the last one on their > site says > leave it out.
