Thanks to all those who responded to my query about the apparent
errors seen on frequency standards.
I am now convinced my problem is caused by frequency error in my TS-
850. Looking at several standards, the errors are as follows
(relative to an arbitrary zero):
60.0kHz: -1.0Hz
75.0kHz: -0.8Hz
77.5kHz: -0.7Hz
162kHz: -0.1Hz
198kHz: +0.1Hz
490kHz (using my LF Tx DDS) +3.0Hz
Plotting this on a graph shows approximately a straight line. This
indicates a progressive error as frequency increases.
As a quick fix, I can now use the graph to determine the readings at
198 and 60kHz that will give me a zero offset at 136kHz. However, is
there a more permanent way of overcoming this problem?
