[Elecraft] Quiet Ductless HVAC System

[Gary Johnson]

At our remote site, we have a new 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.

Exact models are MSZ-GL12NA-U1 - indoor. MUZ-GL12NA-U2 - outdoor.
