[Ham-Computers] ADVICE - wireless

I am curious about wireless LAN.

I have experimented with wireless keyboards and mouse. Both worked fine
until I transmitted. Somewhere in the 30 to 50 watt range these wireless
devices would quit entirely or become intermittent. At my normal 90 watt
level the wireless keyboard and mouse were inoperative. I also have problems
with the indoor/outdoor thermometers. These devices operate around 432 MHz.

Because of this, I question all wireless devices around amateur radio,
especially inexpensive ones. I have found the good (not cheap) 900 MHz and
above wireless phones to be relatively immune. Sometimes running near legal
limit power, there will be a scratchiness on voice peaks.

The exception to this is 75 meter operation. There I have a phone line
running between the house and the garage that is about 35 feet long, and
approximately 12 feet in the air. My 75 meter dipole runs almost parallel
with that phone line and is only 22 feet high. Thus high power 75 meter
operation kills the phone regardless if a cordless phone is used or not.

As soon as I am well enough, I expect to bury that line. Hopefully that will
resolve that problem. If not,  I may remove the line entirely to the garage
and put a 900 MHz or above wireless extension in the garage.
