So,
I was looking for enclosures, and it occured to me - this little transmitter may just bake out there in the sun... we hit 115F sometimes, so I was wondering if anyone encountered like conditions and found a way around it?

Upon contemplating on a new transmitter that's on my "buy" list soon, that requires a heat sink, I've considered buying an enclosure that'll give some extra room in the lower part of the enclosure, cutting some large vent holes in the bottom screened against bugs, and including a whisper fan. The extra room in the lower part is to keep any rain that may blow up into the enclosure from reaching the transmitter. This is just a plan, I haven' tried it yet. Just a matter of fact, the sun shining on a tightly enclosed box didn't seem to bother my SSTRAN which ran 24/7 all last summer. Jim B
Have you considered using a flexible fiberglass panel or aluminum sheet to shade your transmitter box? I found a used aluminum metal printing plate was easily shaped and attached to the mast and protects the transmitter from direct sunlight. If you're worried about your transmitter interacting with the metal you can use a semi-flexible fiberglass or plastic panel and bend and mount it for shade.
After reading these, and thinking of some stuff of my own:
A NEMA Weatherproof Box
A shade bit of fiberglass/aluminum
I will see if I can build some sort of covection venting - but we have monsoons here - so anyplace water could possibly get, in the worse circumstances, it will.
