Sent the program to George, Bon & Hal.
If anyone else wants a copy you can ask myself or them. Please do not
post It in a file section on any groups, (I look in those), It's copyrighted.
It's nothing fancy but does a fairly good job with some nice little
utilities to boot. Old as dirt but hey I did'nt pay for it either.
To the ones that get it, please let me know how you like it. I have
another that's great for calculating transformers and other such good junk.
Enjoy

Allright just found the darn program. Was on an older machine.
Norton picks up a virus, ARRGH, so i will remove it and send it to ypu. You can
share this amongst yourselves but I would appreciate if you DID NOT upload it
to any files section of ANY group , it is copyrighted. Back to removing the
NYB, wish me luck

OK there is a "cute" little program that actually comes
fairly close to calculating effective radio range based on height, power, line
loss(has a cable database), and frequency. Add the cavity losses in with the
line loss. Calculate the portable at 6 feet, unity gain, using worst case
terrain type scenario. I will send it to you.

ok the antenna is from cell site 14dbm 4-element in a
plastic housing, the amplifier is 600 watts capable linear mosfet 8element
hybrid splitters and combiners... but the power supply is up to 65 ampers at 24
volts, driven by a "C" class 130 watt amplifier. the antenna is not on a
commercial tower (no luck here). 20 feet above the house. the line is heliax
andrew semi-rigid. the repeater is in the attic and the line is 30feet. the
duplexer is celwave doesn't like more than 450 watts in.
