> Good but any hope for 1 dB S-meter resolution?

Use Utility and issue !bd0000;

You'll get BD(xx)00(42)00(yy)

xx is indeterminate.  yy is a signed hex byte that should represent dBm
at the Rx antenna jack.


So

yy=93 -> -109 dBm
yy=B4 -> - 76 dBm

and so forth.

It may be that you need to have the S Meter set up for ABS mode for this 
to be accurate.
