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

[Dauer, Edward]

Thanks for the ideas, Mark.  The remote software idea is interesting.  There is a 220 volt outlet already on the outside perimeter deck, which we had put in for the possibility of someday having a hot tub out there – which we never did.  I could put both the amp and the PS in some sort of lockable housing on the deck (which would require hiring a carpenter rather than an electrician.)  I will definitely keep an eye on the development of remote software for the KPA1500.

I remember when we were building the house we asked our contractor about doing something which would have been unusual, I don’t now recall what.  I asked if it could be done.  His answer was like yours – “For enough money, I can do anything.”

Placing both PS and amp where the 220 VAC outlet is accessible is possible; but then I wouldn't be able to see the amp while operating, which I would like to do.  Wouldn't feel comfortable with a 1500 watt amp running way out of sight.  It would also then be in the kitchen on a floor above.  Not aesthetically the best that way, either.

Due to some temporary relocation of my ham shack for a home refurbish, I am using my KPA500 remotely with the KPA500 remote software server running on a spare netbook near the amp, and the client running on a computer near the rig. There is one 100 ft long RG214 Coax between the KPA500 and the rig for RF and one 100 ft small coax with RCA connectors between them for PTT. The amp and autotuner are at the antenna feed and grounded well. The rig away on the other side of the house not so well RF grounded, but there is no RFI so far. That enables me to see the KPA500 status and change the band on the PC in the shack. They don't yet seem to have the remote software for the KPA1500 yet, but it is supposed to be coming.

I would probably accept visible conduit to run power if you can't run it in the walls. As part of the refurbish, drywall was taken out and replaced and the texture matched so new plumbing and electrical could go in.  They also replaced insulation. That worked out well, but it was expensive. There is not really any such thing as can't if you have deep enough pockets!
