Charlie, Yes they work great , Have you tried to copy the WSPR stations on 474.2 KHZ ?

I just ignore the 4 and read the frequency directly in kHz. Works great and for such a simple circuit, there's not a lot of bleed-through. 73, Charlie k3ICH ----- Original Message ----- From: "Ken Roberson" <kwrober...@yahoo.com> To: "Edward R Cole" <kl...@acsalaska.net>; "Jim Miller" <j...@jtmiller.com> Cc: "Elecraft Reflector" <elecraft@mailman.qth.net>; "600...@w7ekb.com group" <600...@w7ekb.com> Sent: Wednesday, September 11, 2013 8:47 AM Subject: Re: [Elecraft] [600MRG] Use of K3 on 600m (and below) > Hello All, > > > I also would like to use 3.5 to 4.0 mhz for the IF frequency > . > I have completed the homebrew 630m transverter to work > With the K3 .
