Wow thanks for all the helpful information. Right now I have the talking sign
TS-100 transmitter which was made by the same company making the procaster.
This transmitter is FCC certified with a built in antenna tuner and also can
be switch to a 50 ohm out put for antenna of choice. I know the person
who built these and he said the TS-100 had the full 100mw input power and
was very close to the same on the output power. Pretty much like the
Stran-5000 transmitter that has an input of 100mw and get the same output power.
I just heard the Rangemaster pretty much outperformed everything. Now it
sound like the Stran -5000 is really pushing the limits on the band.
Since I am doing a true community station I was told that I really needed to
use a FCC transmitter. Now I will check out these other option also.
I knew about the 10 watt stations but I thought it had to be for trafic
like cars going down the road that needed information. Would I qualify for this
since I am only providing Weather ,news and some music to the community ?
10 watts would be really great since I could have a really wide coverage.
CB radios transmitt 4 watts AM and on a tower people have reported getting
out 25 to 30 miles on a quiet night with no skip. This was them using a
60 foot tower and a Antron 99 5/8 wave antenna. That 4 watts really gave them
a great coverage. Wow 10 watts would even do better even if a person
just used a inverted V dipole antenna up 125 ft in the air. This
would be some what omini direction. This way the top of the Inverted V would
high enought for the legs of the antenna to be slope down at the correct angle.
Still I am not even sure if the 10 watts stations can use a regular type antenna
I know even a 100mw output from a part 15 transmitter with a inverted V antenna
would have a really good coverage since a 10 foot antenna reaching a mile out.
Since an inverted V on most AM stations in the higher portion of the band
would only have each leg around 125 to a 128 feet each.
I have worked alot of QRP on the ham bands running only 100mw to 500mw and
reached all the way across the country even using SSB on the ham bands.
So 10 watts with a really good antenna set up correctly would really get out.
The other options sound good also.
My TS-100 is packed away because I figure it would not do well. Maybe with
compression on the Audio and a home built antenna it would do better.
Since I could compress the audio. I just need a really well built antenna.
I have checked the output power of the transmitter since I do have a watt
meter for the AM brodcast band, it will measure from 5mw to 100mw on one scale
and on anothe scale it will measure from 50mw to 1watt.
last scale reads from 1/2 watt to 10 watts. This is a LPAM watt meter.
Also it is certified with the FCC so what it reads the FCC will count it
correct. This is one way I make sure I am very legal. Also I can see
what transmitters are outputing the most power if they have a 50 ohm output.
