I have 2 R4-C's and which behave in much the same way. I believe the PTO generally is not exactly linear from one end of its range to the other.
Regards JB From: [email protected] [mailto:[email protected]] On Behalf Of Henry Foglesong Sent: Tuesday, 16 July 2013 3:10 AM To: [email protected] Subject: [Drakelist] R-4C frequency I just recently obtained an R-4C, made some upgrades to it, and aligned it. It is working very well with one small issue: On all bands, if I set the frequency to the calibrator at the low end, at the high end the dial readout is high by one or more khz when set to the calibrator (depending on the band width). I assume the issue is with the pto, but since I have had little experience with the R-4C, I would like suggestions about the easiest way to correct the problem before I dig into anything. Note: I have checked the calibrator with other frequency standards, and it is on the money. Thanks, Hank
