With the AGC off, and the RF gain backed down, there's plenty.
I don't see it. If you have a meter that at S9 is reading half scale, and
you want to reset a signal level to1 dB, you need to be be able to resolve to
about 0.5% of FSD. We're talking big scales and mirror backing here to set an
analogue meter to that degree of repeatable resolution.
The attenuator doesn't come into it. Sorry Rich, but this 'gold standard'
looks a bit to me like a gilded lump of lead!
