All my MSF clocks and a watch work OK - including a superannuated Junghans one, and several of recent design.  Perhaps you have some local QRM, John.

My QTH is about 30 miles south of Rugby (so no trouble there) but I guess
180 - 200 miles from Anthorn.  I can see a "dissaffected from Newport
Pagnell" letter being drafted before too long to the operator.

Hi Alan,

I have measured the response of the S-meter of my R-75 at 60 kHz, using a
W&G level generator and a Hatfield
attenuator I had bought on eBay some time ago.

At 60 kHz, you need a signal of -67 dBm to have an indication of S9 on the
receiver. To bring it down to S3, I had to
insert using the Hatfield attenuator 17 dB of attenuation. So much for the
linearity of S-meters...

So, for what this test is worth, apparently at my location Anthorn seems to
be about 17 dB weaker than Rugby. The test
is not much scientific, as I didn't take note in the past of the time of the
day when I took the S9 reading, nor of its
repeatability, but as a ballpark indication maybe it can say something.
