[BC] LPAM (was Smallest AM Radiator/TIS)

[WLOYPROD WLOYPROD]

Scott,

You can't legally (a) change the antenna or (b) use a ground system
with the 100mW units... both violate the Part 15.219 regs and the
certification on the unit.  What you can do, and many folks are doing,
is use more than one transmitter and synchronize them using the built-in
synch ports and a GPS system.  You can't really get 5 miles from one
transmitter LEGALLY, in any configuration, from any company, under Part
15.  Tubes or not.

Paul,
  I talked to Keith Hamilton on the phone, and he has some clients
that
are getting up to 5 miles with his box.  You have to know what you're
doing to make it work. I know of one guy getting good coverage using
an
Omnia 3 processing, with a simple unipole type antenna and ground
system.
  I wished you could have met the late James Cunningham out Ada, Ok. I
didn't agree with using tubes, but James used a scheme that made part
15
get out 5-6 miles just using whip antennas.

Scott:

The AM1000 Rangemaster does nowhere near what a TIS does.

If the AM1000 is tuned properly and has some processing behind it, 
it'll get out about 1 mile soild in fair ground conductivity.

If a TIS was tuned properly, had an efficent antenna and the audio 
was better, it'd get out 5+ miles solid in decent groundcondiuctivity
areas.

Come to think of it, with this crazy petition that is out about LPAM,
why not give these people stations with 5-10 watts, or the field
strength limit of 2 mv/m @ 1.5 km, with an antenna no more than
10-15'.
In rural areas, or small towns with no local AM station, that's plenty
to cover a small town, and even cover a high school football game.
IMHO...despite what some say, it's not going to cause nighttime
interference. I know Powell Way on this list will debate me tooth and
nail on this, but if that is the case, then Keith Hamilton's
Rangmaster
1000, Part 15 box should be outlawed as well. It does almost as much
as
the TIS station's transmitter and antenna system. Now this idea would
serve a small community!
