Shack is 24' X 32' with 12' ceiling (formerly a one-room school house).
Building is unshaded in direct sunlight in afternoon. QRO transmitters and
other station equipment give off considerable heat.
Various on-line calculators recommend between 19k and 30k BTU with pertinent
data entered. The old a/c is 23k, although at 40 y.o. it probably doesn't have
that much cooling capacity any more.
Besides RFI considerations, I have to figure out a way to get the old one down
and the new one up in its place. Hole in the wall is 8' high off the floor.
Most units I have checked take the same size hole and weigh 130-150 lbs.
