[Milsurplus] GRC109/R-1004A arrived!

[Bry Carling]

Interesting thoughts Richard...

I have never heard any amateur say that his GRC109 failed due to overheating...

Also note that the case is a giant heatsink and painted black which is the best color for 
re-radiation of heat to the outside. Now maybe if you used it for 8 straight hours at field 
day here in FLORIDA, you could overheat it! Now there is an idea for an experiment and 
a magazine article.,.... NAH!
