I use the SPOT feature on my K3S to zero beat the carrier on WWV. This gets me to +/- 1Hz. If it is more I'm inclined to tweak the reference such that it is accurate.
As to posting spots, I usually post to the nearest 1 KHz. Thus from experience, I have little confidence in the display accuracy of other radios. 73 Bob, K4TAX Sent from my iPhone > On Feb 21, 2019, at 3:44 PM, N4ZR <n...@comcast.net> wrote: > > Ever since I have owned my K3, I have noticed that most spots put the K3's > receiver above the actual frequency of the spotted station.
