Oh yeah. I'm well aware of that. I've installed a heavy-duty fan that sends air straight across the fins of the TX radio. This is my second successful system that I've built. The first was out of an old GE Exec II base. Converted it to repeater with a few jumpers. Knocked out a few 2m repeaters and a 467 system 60 miles away after I installed it on a mountain site.
Oops!
It's down at my shop til I find a new site. The site owner said $50/month, then hiked it up to $200/month. I only paid him $100 and left the site after he told me this and when I found out that he disconnected my system and powered it off because he didn't want to listen to the subtle audio leaking out of my aux speaker.
Eh, oh well. His loss, and my gain. The site wasn't even worth the $50 to begin with... Looking at another, twice the height and a commercial site at that for around $100. Better deal me thinks.
... (blah blah blah...)
