I am an active ham with full previledges, only thing causing
interference with Wi Fi in my house is microwave oven in the kitchen.
Dimmers, GDO, wireless thermostat, cell phone cordless phone, various
HAM rx/tx are all fine. No problem.
In an office once there was a Motorola walk-talkie radio and charger
that sat right next to an old x86 computer. Seems that was killing the
hard drive of the PC?? Never really found out for certain, though.
Once I had to work on a problem caused by air port radar.
Nearby large commercial computer system installation was going crazy
at certain interval that was when the rotating radar antenna was pointed
at the site.
I had a 92' Plymouth mini-van and read reports of that years crop of
Chrysler engines has a bad habit of stalling if they drove close to some
airports at the time the radar beam was pointed in their direction.
Apparently the radar beam would shut down the electronic ignition.
We are currently experiencing a problem with a Sony cordless phone (Sony no
longer makes cordless phones). This phone will shut down our in-house WIFI
network whenever one of the phones is in use. We are looking for a suitable
replacement that does not confect with our Nortel wired phones the way a
Siemens cordless phone did. We returned it.
UL, CSA and all the rest are ONLY concerned with safety, not interference.
So they have nothing to do with anything.
The FCC does however, and if the thermostat met FCC Part 15 or the Canadian
or EU equivalent, then its radiation is tested and rated; right on the
product. No notice of Part 15, it's an illegal product for NA sales.
In addition to that, if you do have interference issues and passed Part
15, not only does the device's paperwork tell you how to control it, but
gives you contact information in the event you have trouble with radiation
through the air, power wires or peripheral connections. So I'd say RTFM is
still something you have on your to-do list, except rather than try to
slightly move the item etc., you gave it away.
So often we create our own liver-quivers because emotion takes over
instead of logical common sense.
Newsgroups are great places to get assistance.
Started having trouble with the home WiFi system. Worked on it for a
month until I found my wife and place a 2.4Ghz cordless phone base
near the wireless router. I hadnt seen it because it was carefully
hidden behind some books.
