Subject: Any interest in X Logging Program?
To: [e-mail]

Hi all,

I'm starting to work on a logging program which will run on a unix workstation
running the X11 windowing system.  I realize that most people don't have
X11 workstations and radios in the same place, but I thought maybe somone
out there might be interested.  It will support interface to an Icom radio
as well as logging and awards tracking.

Is there any interest in this?  I'd be happy to give out copies once it is
done.  Also, are there any suggestions or requests as to what you'd like
it to do?  For example, I could probably add code to talk to other radios
but I would need details on how they work...I only have an Icom.

If you would are interested in the program and/or have suggestions, send
me mail at [e-mail] and let me know.  I'll try to
incorporate as many suggestions as I can.  I also may need help with beta
testing, particularly if I add support for radios I don't have.

If the response is overwhelming I'll probably just find an FTP site that
I can put it on to make it available.  If the response is non-existant
I'll just go off and use it myself. :-)

                 SUPERBALL 1-94: LAST CHANCE TO COPY

Superball 1-94, the test of superpressure balloon technology
carrying amateur radio beacons, is still transmitting.

The balloon, launched on January 7 at 1626z, burst about three hours
later and landed in Utah's Uinta mountains, likely between 9500 and
10,000 feet elevation.  A search party, on January 8, got within
about two miles of the believed crash site, but were unable to
continue due to steep terrain and deep powder snow.  Whether
recovery will be possible before spring remains uncertain.

Three beacons on the payload are still transmitting and have enough
battery power to continue for at least several days.  Reception
reports are solicited.  Reports from Illinois and Ohio have
indicated good signals.  Of particular interest are reports of
reception through the Russian RS satellites, because this will give
an idea of how practical this method of relaying telemetry will be
for a later, longer-lived flight.  Reports should include the
receiving site, date and time of reception (preferably in UTC), and
the frames of copied data.  The frequencies are as follows:

 Frequency     Satellite    Satellite Output
                            Frequency
 -----------   ---------    ----------------
  21.229 MHz   RS-12        29.429 MHz
  28.322 MHz   (not on a satellite input)
 145.871 MHz   RS-10        29.371 MHz

The 21- and 145-MHz transmitters are on for three minutes and off
for nine.  They send CW (not MCW) carrying telemetry information.

The 28.322 MHz beacon simply keys on and off and does not attempt to
send code.  This beacon, alone, has solar power.  The keying rate
indicates whether it is operating on solar power or from batteries.
Solar power is indicated by a rate near 40 pulses per minute;
battery power by a rate near 20 pulses per minute.  It is unknown
whether recent snows may have covered the solar panel.  This
transmitter may die as batteries run down, and then come back to life
next spring as snow melts and the solar panel is again exposed to
sunlight.

   Unfortunately, it's been enough years that I couldn't tell you where to
look for information.
   There's a commercial unit for cars for this purpose; last I saw it it
was about $129.95.  Last I investigated making my own, it would have
cost me about $300 for the Peltier devices alone.
   Peltier junction devices are quite expensive and probably not a good
choice for this.  Get a small refrigerator instead.

   I'd recommend an AEA Hot Rod (tm) antenna or similar.

   (There's one laying somewhere on the Continental Divide Trail,

   2nd choice is a j-pole made out of TV twinlead. Not really that
    great unless there are usually trees around to hang it in.
    Even then its probably too much hassle for the hiking/backpacking

   There are beams that disassemble, but unless you really need the
    few dB of gain and are going to stay put for a while, I'd say
    they are too much hassle as well.

Amateur Radio operators assigned to a local government's RACES
unit.
1. Write or update the RACES Plan.
2. Agency policies, procedures, practices and philosophies.
3. Message form and message center (handling) procedures. Keep it

4. Names and titles of key local government leaders, department
heads, and division chiefs.

Should be quite easy to challenge your coordinating body with an

I think you are confused with the licence information available from the

Depending on the formulas used for the computed contures I have seen five

enclude diffraction. We know our repeater plays over hills and can be

 For packet I only use 5 watts.. But since this is my only radio, I have
to use this one for voice also, and in order to hit the one repeater, and
make my transmission readable, I have to use 50 watts..

I think you are referring to the picture of WA1EKV, who lives a short distance
from here. His LP with it's 60 foot boom looks positively SMALL, compared to
the 4 element, full size 80 meter beam he used to have up. Both are pretty
impressive sights!

HORSE-FROCKEY !!! If someone wants to find a repeater's location for

More BS.... The REAL reason this information isn't given out is that
Cordination Groups want to wield their coordination POWER without
fear of any questioning their declarations. With all the data on
a repeater (lat/lon/haat/erp , etc ) you could challenge or even
ignore their refusal to coordinate a repeater on a frequency you
have chosen. I suspect less than 1% of the so called coordinated
repeaters in operation today have any sort of REAL engineering
study including contour maps done on them. Most have been 'coordinated
' by either first come first served ---- or Good Ole Boys Network
methods.

This information is publicly available for EVERY commercial radio
 and televion station in the USA and there is absolutely no reason  other
than small minded POWERMONGERING  politics that this isn't available
for amateur repeaters.

I dare ANY so called coordinating group to prove me wrong by PUBLISHING
there engineering studies for all their "coordinated" repeaters.

All we'll probably hear is eithe silence or a crescendo of flames
about how their "integrity " has been insulted....but the engineering
studies generally don't exist so we will never see them!
