As carried out by Wullie GM0MZB and noted down by Chris I used a fixed forumula to do the dBm to µV conversion, was a little off compared to the measured value (probably because of the precision level or stability) next time might stick to µV and convert to dBm (as he awaits comments from MZB...

I have had cause for concern about the heat generated by my 706mk2g even in the receive mode. It appears that the 706mk2 unlike its predesessor the 706 does not keep its internal blower running in the receive mode an as one would guess acts as described. There is a none" icom" mod to be found...
