There is an email list for Space Shuttle elements, which need more
frequent updating than most satellites.  If you want more information
about the Shuttle Elements List send a message containing the line
"send info/elements-mailing-list" to "listserv@telesoft.com".  The
address to write to for a subscription or information is
"elements-request@telesoft.com" (or just reply by email to this
posting). 

For elements of interest to radio amateurs (primarily OSCAR
satellites), AMSAT has a Keplerian Elements mailing list, send an
email request to listserv@amsat.org for list information or for a
subscription to the "KEPS" list. 

For other satellites, there are weekly news postings from Dr.  TS
Kelso in the newsgroup sci.space.news.  If you have ftp, check under
/pub/astro on "ftp.funet.fi" and /pub/space on "archive.afit.af.mil".

It wes quite awhile ago.  As I remember, I ran around 10-20 mA through
a diode which was in shunt with the 50-ohm RF path.  I looked at the
output on a 100 MHz oscilloscope and made a visual judgement on how 
distorted the waveform was.  Most of the testing was at 14 MHz, although 
I did try lower frequencies as well.  As I recall, the 14 MHz signal 
looked like a pretty good sine wave, but by the time I got down to 1.8 MHz
it was starting to get pretty distorted, although still not nearly 
as bad as a switching diode.  

Sorry I don't have more qualitative data.  Maybe someone on the net
with more time could measure harmonics and IMD on a spectrum analyzer
and report the results.

Now that I am actually giving serious consideration to getting back on HF 
after many moons, the issue of QSL cards needs to be brought up.  I have
2 different kinds now, one generic and one commemerative. BUT, I used to
have (what I thought was) a pretty cute card when I lived in Germany.  I 
would love to get more of these made up with my US callsign on them.

Now here's the catch.

They were printed by a company called Raum from Philadelphia.  Does anyone
know if they are still in business??  I couldn't find an add for them in
either QST or 73's.  If they are, I would appreciate a phone number from anyone
who has it.
Barring that, are QSL designs usually copyrighted??  Can I get someone else
to print cards just like this one??

Any info will be greatly appreciated.  Who knows, maybe I can be a big gun
DXer too.  (Yeah, right.  With my TS-820 and 5BTV.)

Well, since we've been talking about closed repeaters in general, and their
effect on the 440-449MHz section of the 3/4m band in specific; the simplex
frequencies for fm voice are: ... 446.00MHz.  Oops!  Did I say frequencies?

I have a small military surplus (airborne) VLF receiver which
I purchased at a hamfest. I ran from 28V and I modifed it for
12V operation.  I would like to learn the military i.d. number
for this receiver.  It has no manufacturer markings or i.d. 
whatsoever.  The receiver has the following controls:

6-band bandswitch for the following ranges-

6 - 63kHz
30 - 70 kHz
70 - 125kHz
115 - 185kHz
180 - 280kHz
270 - 420kHz

AM/LSB/USB switch
3kc - 10kc selectivity switch
RF gain control
AF gain control
Tuning

The size is about 1/3 of a cubic foot.

Anybody out there have one of these receivers?
Who made it?  Any documentation available?

I added a +20 dB preamp to it and it works quite nicely
with my 1m broadband loop.

Any help from fellow VLF'ers appreciated!

At that rate, you only need 13 members to break even.  Are your 13 members
really holding 19 frequency sanctions?  

I guess that's my main beef with closed repeaters.  Our frequencies are
a valuable commodity.  On HF, usage level is self-regulating:  If an under-
utilized channel develops, someone will immediately find it and use it.  
But on the repeater bands, a repeater or control link effectively "owns" 
the frequency, as a practical matter.

I believe only open repeaters should get clear channels.  The closed
machines should have to share channels with each other, using P/L or
some other method to avoid interference.  I realize this is being done
to some extent, but there are far too many under-utilized frequencies
with only one or two closed machines assigned.

Distribution: usa
Date: Tue, 5 Jan 1993 21:29:11 GMT

My first impressions of the Yaesu FT530 handheld are that it is a very nice
radio in a small package.

* The backlighting is excellent!  It is edgelit on both sides of the
display, and the keypad is also nicely lit.  It offers delayed
lighting for longer viewing.  Pressing the function key then the
backlight keeps the light on until you turn it off.

* The radio's power button is on the side - nice if you want to keep
the volume controls where they are, but I'd prefer the power button to
part of the main volume control.

* The dual-inband receive is nice, though I would like to clarify one point 
  (whether it pertains to just my unit or is universal) -

  The 70cm transmit side is HEAVILY susseptable (sp?) to intermod.
This is the right side of the display.  It can also act as receive for
2m, which is also susseptable to the intermod.  It is not safe to say
70cm alone is the problem, but rather 70cm transmit/2m receive (the
VFO on the right side of the display) is not tight enough for intermod.

* The supplied manual is nice, but I didn't find it covered everything well
enough.

* A very nice feature of the radio is the ability to have both a 24
hour clock and battery voltage display.

* I feel the supplied belt-clip is sturdy, though I have yet to really
field test it.

* The indicators for BUSY/TX for both left and right VFOs are too close 
together

* It is nice to be able to transmit directly on the input of a
repeater and be able to monitor yourself on the output in the
"sub-band" so you know when you have timed-out the repeater. :)

* It also has an AM detector which can be manually turned on or off.

* Too bad stereo headphones don't separate the left and right VFOs.

Overall, I really like the radio.  The Multi-Function LCD speaker-mic is
on backorder.

Besides the nasty intermod problem in the right VFO (each band has two
VFOs), the radio is great! (Redundant, I know).


The radio also comes standard with 2m receive from 130-174 Mhz and
transmit from 140-150 Mhz.

It also receives and transmits on 70cm from 430-450 Mhz.


I have yet to find software (keypad) mods for it.  Holding down the up/down
arrow keys then turning on the radio doesn't seem to do anything, at least
that I could see.

I am NOT opening the radio until it is out of warranty, if even then.

Hope this was helpful to anyone interested.

  Yep.  All the SWL cards I have received over the years, if I remember

  former Soviet Union.  I do believe, but may be wrong, that some countries
  require SWL activity and some number of QSL cards received by the SWLer
  as a prerequisite for an amateur license.  However, SWLing is a popular
  hobby in and of itself.

I had several experiences with county hunters about 10 years ago.
I spend a lot of my time camping - sometimes in very remote places.
While on my way to and from these place, I often went through some very
rare counties and used to enjoy being at the "dx" end of a pile-up.
Eventually, I had some very frustrating experiences where the net control
station wanted me to - in effect - guess what the report was that was
being sent to me.  I could tell that there was a station on the freq,
but nothing he said was intelligable!
After many frustrating tries, I finally declared no contact. The net control
station got really upset with me that I wouldn't play by their rules -
which were if you guessed right, it was a good 2-way qso!!!
I don't even want a rare DX card under those conditions. What is the
purpose?  As I said this was about 10 years ago, and I hope it was an
isolated instance, but judging from some of the DX "qso's" I've heard
on the bands, I doubt it.
