-
- Yes. Get your antenna as far above your setup as possible.
- Ground everything to an excellent earth ground.
-

-
- I'll ignore the "if not."
- Put lots of chokes on your cables; especially your monitor cables.
- Shielding your monitor may help most of all!

- Looks like this guy is going to fit right in. He has managed to
- combine his profession (ambulance chasing) with his hobby (radio). He
- will be happy to find that all too many of the denizens here share
- his hobby and have his profession as their hobby too.
-
- This is going to give much more milage to the "Can I order a
- pizza if I refuse to pay the delivery boy" questions.
-
- My understanding of amateur radio is that 70 years ago, the old
- farts just wanted to sit around and talk about radio theory while the
- young Turks wanted to build radios and transmit with them (using CW
- even). Now we seem to be at a stage in our history where the old
- farts want to sit around and discuss radio rules and regs while the
- young Turks want to build radios and transmit. Things haven't changed
- much, but I think they have changed for the worse.
