[Elecraft] FW: How far can the KPA1500 amp be from the PS?

[Rick Tavan]

Although the KPA1500 can already be operated remotely, comfortably, using
KPA1500 Utility's Operate page, and although the eventual release of
KPA1500 Remote will be even better, I would advise against putting the amp
outdoors. Even if the housing is 100% water tight forever, Murphy almost
guarantees that the first failure that causes you to want to access the
amplifier will occur during a downpour or snow storm. Just run the 240 VAC
line into the shack somehow (and the 120 VAC line suggested by K9YC). Worst
case, you'll need to run conduit along a wall and maybe ceiling, perhaps
covered by a soffit. Some folks even put up a false wall of paneling in
front of an existing wall that they can't dig in to.
