[RFI] Mini-Split for new ham shack

[Gary Johnson]

> At our remote site, we have a year-old Mitsubishi 12000 BTU mini-split. It is located right under our 30 ft tower with Yagis and wire antennas. There is no detectable elevation of the noise floor nor any buzzing birdies on 160 thru 2m. An external thermostat adapter was installed, and on the cable to the thermostat I did apply a proper choke, just in case. All AC wiring is in Sealtite or EMT conduit.

It?s a 10x12 shack with ~12 feet high ceilings, so it?s a small space, but it can get pretty hot up there in summer (sierra foothills of California).  I only have ~30 amps total available so will also need something efficient.
