Just finished installing the DSP board after the return from Aptos and then 
loading the latest program updates.  I know when turning the power control 
there is a known dead spot between 8 and 13 watts which I hope them can 
correct soon, but I noticed that there is an increase in the receive gain at 
this point.  When I turn the Power knob from 8 to 13 in receive mode the 
receive gain jumps up 1 S unit almost like the preamp was turned on.  I 
tried different setting of the preamp and the ATT but the gain wll always 
increase 1 S unit over whatever the S meter is reading when the power level 
indication moves from 8 to 13 watts..  I am looking at it on 6 M and have 
not tried it on other bands but wondered if anyone else notices this? 
Nothing I can't live with..

Regarding the dead spot 8-13 watts, I use a solid state amp and I can run 
either down around 400 watts or I can run up near 1 Kw but not in between 
due to the dead spot.
