Hello Elecraft, I would like to request a change in the firmware that would allow me to Run Homebrew transverter on the new 630M band ( 472 - 479 KHZ ) I would like to use the K3 as an IF on 80 meters. My LO is running at 3.5 mhz Its easier to build a stable oscillator on 3.5 MHZ than the higher bands. Thanks for all the nice Elecraft products . 73 Ken K5DNL
