Already figured out, by Jerry Pournelle and others. You take a
satellite orbiting at geosynchronous altitude, and lower a rope. In
order to keep the satellite in balance, you extend a rope the other way
(maintaining center of gravity at geosynchronous altitude). If the rope
is strong enough, you would be able to extend it all the way to the
surface of the earth. (When this idea was first proposed, in the late
'70s, the required tensile strength was 3-10x greater than the high-tech
materials of the day.) 23,000+ mile tower high enough for you?

            Near Outer Space Transportation System (NOSTS-1)
             Balloon Launch - Clear Lake Amateur Radio Club
                        Sunday - October 9, 1994


Near Outer Space Transportation System utilizing a 12 foot diameter
helium balloon as the launch vehicle.  NOSTS-1 is an amateur radio
experiment which will carry a various payloads in a package weighing
less than 6 pounds.  All interested hams are invited to participate.

The payload consists of:

* 2 meter packet on 145.75 MHz simplex - the node name for digipeating is
  NOSTS-1, the mailbox callsign is KJ5MX-6, the beacon IDs as KJ5MX-3.

* 10 meter voice beacon on 28.322 MHz Double Side-Band with an ID interval
  of 33 seconds

* Beacon on 29.420 MHz sending "CW" beeps that correspond directly to the
  outside temperature.  At 70 degrees Fahrenheit the beep rate is
  approximately 200/min.  To calculate temperature from beep rate the
  formula: Temp(degrees F) = [0.56853 X (Beep rate)] - 38
  The antenna for this device is a 2 meter dipole cut to enhance the 5th
  harmonic at 147.10 MHz for direction finding purposes.

* Beacon on 224.72 MHz for direction finding purposes only.

* Potential secondary payloads may include a 10 GHz gigaplexer beacon and
  a 2 meter uplink (147.435 MHz), 70 cm downlink (440.95 MHz) FM repeater.
  Final announcements on these payloads will be made on launch day.

The Clear Lake Amateur Radio Club Balloon Launch Team wishes to thank
Andy MacAllister, WA5ZIB and members of the South Texas Balloon Launch
Team for assistance, advice, and use of 220 MHz beacon, 29.420 MHz fireball
transmitter for this launch.

An informal simultaneous HF (7.155 Mhz or up for QRM) and UHF (442.750 SE
Houston | 444.275 MHz NW Houston repeaters) net will be held at 7PM on
Saturday October 8th for final updates.  The 40 meter net on the same
frequency will be active immediately before and during the flight.

The lauch site will be west of the Houston area and the direction of
flight will be from west to east.  Coverage may extend several states
on some modes.  Reception reports including frequency, time, and
YOUR location are encouraged.

From: [e-mail] (Mike Gordon)
Subject: Converting Motorola Pulsars to 2m

A friend of mine recently picked up 2 Motorola Pulsars at a fest.  These
units are the VHF pre-cellular mobile phones that operated in the major cities.
Since these units are full duplex (with duplexers, not SAW filters) and have an
output of around 30 watts, they would make excellent mobile/special event
repeaters.

Does anyone have any info on converting these units to 2m repeaters?  I don't
think that the RF details would be that difficult, but what about disabling the
"brains" that were used to make it a phone?  (ie. dialing, selective calling
for ringing, etc)

I would not need to have them on the typical .6 mhz splits, which could cause
some difficulty with desense.  In fact, I'm looking at using one for our
Civil Air Patrol search and rescue team which runs 143 mhz inputs and 148 / 149
mhz outputs.  (And yes, CAP can use modified commercial and/or HAM equipment
if it passes inspection on signal quality, interference, etc.)

Of course, I can come up with the typical repeater controller circuitry for
IDing, timeouts, etc.

Any help you give me on this would be GREATLY appreciated.

Mike Gordon  N9LOI  [e-mail]

PS:  Please help support your local Civil Air Patrol unit.  CAP searches for
downed planes and missing persons, as well as providing disaster relief during
floods, tornadoes, etc.  CAP also has youth programs that teach cadets respect,
honor and self-worth.  These lessons help out cadets become highly successful
students and leaders.

Although the Civil Air Patrol is the official auxiliary of the Air Force, we are
run as a non-profit corporation similar to the Red Cross.  While we do get some
money from the Air Force, we really depend on donations from our members and the
public to help continue our work.

Mike....

     Congratulations.... Welcome to the club... The next several weeks
will seem like a lifetime while waiting for the mail, but, if your smart,
you'll keep working for an upgrade. It will keep you interested in the hobby
and help the time to pass. I passed the requirements for General on a
Saturday and received my Tech+ ticket two days later on Monday. That was
quite a thrill ! I was kind of lucky but unlucky... It took 13 weeks for my
original ticket to arrive. It made me real anxious, but, studying for
General kept me busy... I was listening to CW tapes every day on my way to
work and back...

                   Happy Hamming...

Look up the "LOG-PERIODIC ANTENNA" that is what the standard TV antenna is.
A log periodic antenna is a series of dipoles for different frequencies,
with the feed alternately fed.  Meaning that the is crossed over left to
right.  And don't forget, the spacing is very important too.

Good luck.

Subject: Should I build or buy a TV antenna?

It all depends on the general reception in your area.  Are you in a
Metro area?  If the signals are generally strong, I would just build
a small dipole or hang a little wire off the TV connector.  That is all
it takes down here, no $50 needed.  It always amuses me to build a small
folded dipole for FM and beat the reception of the big, fancy Radio
Shack FM antennas costing $30 and more.  BUT, if you are in a fringe
area, I would probably go and buy a commercial antenna...and a small
rotor.

The ARRL releases a list of what call signs have been allocated, on a
monthly basis. I believe they get it directly from the FCC. I have seen
it posted both here, Compuserve, and packet, as well as QST.

Thus, what you are asking for already exists.

Subject: Why is aviation COM VHF *amplitude* modulated?

Aviation uses AM instead of FM to avoid FMs "Capture Effect". On FM when
2 stations Xmit at once your reciever will lock to the loudest signal
and ignore the other. On AM the 2 signals mi and create a hetrodyne
(Beat Note) and alert the reciever to the presence of another signal.
This way any weak signal requiring assistance stands a better chance of
gaining attention whereas using FM his chances of being heard are gretly
reduced. 73s from Reno, nv de Tim, NC7K...sk

I'd speculate (from an earlier post in this thread) that it's due to
the characteristics of weak-signal AM vs. weak-signal FM - and not the
capture effect.  An AM signal can be usable when it's right down there in
the atmospherics, while an FM signal must be greater in amplitude than
the atmospherics to be usable.

Does anyone have a definitive answer?
