[TenTec] Cool Orion

[Tommy]

Hi Jack,

That's good to hear. My Orion is completely open on all sides, I use the TT
heatsink fan, and I very seldom run more than 30 to 40 watts into my Titan
3. I think this is a heat build-up issue internal to the Orion, without
respect to how much RF power you running. Mine certainly is not bad, just
noticeable.
