[Elecraft] Re： XV50, XV144, XV222 Assembly Manual

The heat is NOT quite generated from the 3 x 160 ohms attenuation resistors.

It does come from the heat dissipation from the RF power module RA30H1317M when operating under Elecraft published specifications i.e. 20w SSB/CW or 10w continous carrier modes e.g. FM.

I guess my XV144 doesn't get hot because I drive it with 1mw.  There
are holes in it above the attenuation resistors.
