Try Gerhard's suggestion in the 2005 posting below. He changed FP-R4 and FP-R5 both to 56k and got +/- 700 Hz RIT range for his K1. I believe others tried 47k and got something closer to +/- 1 kHz. Ignore the "C7 change" stuff in the posting. Mike / KK5F > Date: Fri, 4 Mar 2005 18:38:52 +0100 > From: "Gerhard Schwanz" > Subject: [Elecraft] K1 RIT Mod!!! > > Hi again, > > I just soldered a bit.
