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?
