[Antennas] Can we talk about WLAN antennas here?

Sat Jul 29 00:10:30 EDT 2006

Hello David,
Another strong signal heard from. Thanks for the information. I hadn't 
really looked into it.
When I was doing some maritime mobile work, I got a clarification of the 
FCC's rules.
If I operated on voice from N1EA/MM in international waters and contacted 
another station in the USA (stations on USA registered ships and aircraft 
are considered in the USA when in international and national waters, and 
under dual laws when in port.) and someone wanted to make a telephone call 
to Australia, I could do it this way. I could call a station in the USA and 
have a phone patch to that station then they would call Australia on the 
land line collect. This was legal because third party traffic only existed 
over the radio connection and not the telephone/telegraph connection. I had 
such a letter which was signed by a Mr. Fowler if I recall correctly from 
the FCC at one time.
It sure surprised me - and the other interpretation also surprised me. If I 
am on 20 meters and a amateur station from Egypt calls me and asks me if I 
can relay a inconsequential (say hello to) message to K1TTT by telephone. I 
can do it because K1TTT is a licensed amateur for that frequency so he's not 
a third-party.
Have you heard W1PL recently, I got him a special telephone for the deaf a 
few months ago. Poor Laci he can't see and he hears poorly but what a fist! 
I understand he had help on his antennas - the feedlines were messed up.

Just remember though, if you are operating outside the limits of the
unlicensed assignment you must:
1. stay on the proper channels, not all of them stay within the amateur
allocation.
2. obey all the other amateur regulations, especially commercial use
limitations which would make it illegal to visit many web sites, let
non-hams exchange email or im with certain countries, and probably lots of
other nasty little gotcha's.
3. you would of course also have to be in control whenever it was being used
by a non-ham...something they may not understand when they try to use it
after you go to bed or leave the house and turn it off. And to make sure
you were staying legal you would have to monitor all the transmissions,
which could be hard with normal packet sniffers... especially if the user
visited a secure site, so they would be off limits also. And you would have
to have a way to cut off non-compliant users, something they may not
understand very well either.
