Topband: One way prop

[Greg - ZL3IX]

So you've never given anyone 5/1 on SSB on a quiet band, Richard? That's 
possible on 10m on a good day. What you're describing seems to me to be 
the R value, not the S value. You may have noticed me giving reports of 
469 or 479 on 160m when propagation is good but I have a high noise level.

'Knob twiddling' should not affect the S meter in a well designed rig. 
On my SDR, provided that a signal is strong enough to overcome noise 
levels on all settings, I can switch attenuators and preamps in and out 
and it makes not one jot of difference to the S meter reading. S9 is -73 
dBm at the antenna connector no matter what.

73, Greg, ZL3IX

I don’t think in all my experience that I have ever given a signal report based on an S meter reading, in fact I didn’t even realise that my current rig even had one. My reports are always based on a comparison between the background noise and the signal estimated by what is between my ears. Thus S3 is barely audible and anything above 6 or 7 is easy copy. The meter reading can be set to any value you like by knob twiddling. If somebody wants a comparison on different antennas for example then I would use the height of the spike on the panadaptor but I certainly would not rely on its calibration.
