The 930 S-meter is quite logaritmic. Around S-2 it´s close
to 1 dB and S-8 to S-9 is close to 5 dB. So you got to
be careful with that radio when using the S-meter. Above
S-9 it´s quite decent by the way.
The FT-1000D forexample isn´t perfect either but much
more "perfect" then the 930. I have checked the S-meter
on the 1000D but don´t remember the figures, just
remember that I tought it was "decent".

I also have a single HF2V far away from the 4 square and

have done on the air tests with EU stations switching back and forth between the two setups. I'll admit the gain testing may have also been affected by propagation, etc. Also, I've done a lot of receiving testing looking at the differences on the S meter on the rig (930S) while switching between the two. What I will state is that there is definately an improvement. Phil


Most S meters I've tested are OK over S-9, about 5 dB per S unit near S-9, and drop to very low db/S unit values at the low end of the scale. Of course some are better, some are worse.

A few of my radios are 1dB per S unit at low S unit
readings, although they are very close around S9 plus.

I think the fact most S meters are less than 5dB per S unit
is behind manufacturers of miniquads and things making
exaggerated gain and F/B claims.
