Please reply off list only. For those who want to follow this discussion, just send me an email and I will be happy to include you on my own little list, that was established some time ago when I sought advice on replacing my central A/C system without generating RFI.
After the previous discussion, I successfully had my old central A/C system, which was broken and non-repairable, replaced with a new system using old enough technology that it generates no RFI. However, that did not address the fact that my radio shack (which is a corner room facing south and west) is too hot to be comfortable during the hot season here in the Phoenix area (and that is true even *before* I turn on any of the radio equipment). Adding a conventional window A/C unit is not practical, as the windows in the room are obstructed by furniture and equipment. For the same reason a "portable" A/C unit (that stands on the floor, with a big hose connected to a window) is not practical. What should work is a "mini-split" room air conditioner. This consists of a condenser unit mounted on the outside of the wall, and a separate evaporator unit mounted on the inside. The units are connected together through just a small hole in the wall, maybe 3". These units are fairly new to the U.S. maket. Most people here don't even know that they exist. But when I searched homedepot.com I found that many different models are available, priced from under $1000 to several thousands. Home Depot sent an installer to my house. He told me that every model available uses variable speed motors, so I can't just buy a single speed unit in order to avoid RFI. Also, none of their customers would allow me to go to their house and let me listen for RFI while standing outside their house. However, he said these kinds of systems have been marketed in Europe for at least 20 years, and homes there either have no A/C at all, or they have mini-split's. So, all I have to do is talk to some hams in Europe, that have A/C, and ask what model they have, and whether it generates RFI. So far, I have discovered that my sister in Europe has a mini-split, but of course she cannot listen for RFI. So rather that turn on a radio and start searching for European contacts, I thought I would once again draw on this list. I know there are lots of Elecraft users in Europe, and surely some of them have A/C units. Please, guys, let me know how that is working out with respect to RFI! Again, please don't discuss on this list; I will be more than happy to include you in the discussion using my separate little list, and if you are kind enough to give me some information, but don't want to receive email, just let me know. Thanks in advance, 73, Erik K7TV ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
