Well, we all strive to be correct in our research and writings. And I
am finding it very interesting that the older the articles I find, the
greater percentage cite "Orbital."
And as an editor and student of the use of the English language, I can
envision an uninformed editor or proofreader "mis-editing" a
submission of "Orbital" to "Orbiting..."
I use this in my presentations as a "trivia" question: "OSCAR is an
acronym - what does it stand for?"
I think the maintainance of the true, historical record is important.
And would respect those SKs who have passed on since their OSCAR
ventures...May I browse through those 26 boxes next time I'm in the
San Jose area???
Thank you...

And for some obscure reason, the US Navy had a constellation of OSCAR
satellites. These made up the Transit navigation program. The Transit
system used Doppler shift on frequencies of about 150 MHz and 400 MHz
for ships to determine their position.
Just a bit of trivia.

Clint,
As the current President of Project OSCAR Inc., I felt some responsibility
to answer your question. I went through our current Constitution and bylaws
and find no reference to the original definition of OSCAR. I am inclined
toward "Orbiting Satellite Carrying Amateur Radio" but that is just my

Wow...this gets weirder and weirder...
I can "sense" how a writer or an editor used "Orbiting" to replace
"Orbital"without blinking an eye back in the '80s or '90s...or a
proofreader changing "Orbital" to "Orbiting" back then and thus
changing the acronym in all future literature...
I started this all because I use it as a "trivia question" during my
satellite presentations: "What does the acronym, OSCAR, stand for?"
I do not mean to irritate anyone nor instigate trouble (honest,
Rosalie!).
Thanks for the feedback!

The January 1962 issue of CQ announced the launch of OSCAR (later called
OSCAR 1) and says Orbiting Satellite Carrying Amateur Radio. However, page
32 of the February 1962 issue shows a image of a "Father's List," with OSCAR
Logo saying Orbital Satellite Carrying Amateur Radio. The list was flown
onboard the satellite. So, with the letterhead on the satellite, I tend to
accept Orbital Satellite Carrying Amateur Radio.

Having used NOVA for years and manually tracking/tuning, I decided to
purchase SATPC32 at the AMSAT Booth at the ARRL Convention in
Anchorage this last weekend. I have both a FT-847 and a FT-817,
which I understand will tune with SATPC32. Once I get it
operational, I will post a report here on the -bb and have a detailed
article on getting going with these two radios on my webpage:

Bob,
Regarding 1296-eme: The 12-foot dish will do fine on eme and the 70w
amp will do fine as a start, especially if you use JT65C.
Is your patch feed circular polar? EME on 1296 is RHCP in transmit
and LHCP in receive. The switch of polarity sense is due to the fact
that reflection at the moon reverses the sense of polarization. This
might be difficult to achieve with a patch feed. Many eme stations
are going to the septum feed since it produces both senses of
circular polarization and eliminates the need for a high power coax
relay. See http://www.ok1dfc.com/EME/emeweb.htm for septum designs.
50-feet of LMR-400 will lose a lot of power at 1296 (2.4dB loss);
only 42w will reach the dish. You can solve this two ways: upgrade
to 1-5/8-inch hardline (61w will reach the dish) or mount the
amplifier at the dish (on the back side would work well). Then use a
10-12 foot 1/2-inch hardline to the feed so that 95% of the power
reaches the feed. Typical stations on 1296 eme run a minimum of 150w
and average 200-300w. I understand from talking with Gordy, WA6ZKY,
that a 150w amp is being developed by KJ6KO. I probably let the cat
out of the bag so my appology to Greg.

Hi Wouter
Bear in mind that this happened about a minute or two before LOS and took me
by surprise so these are not scientific observations.
I was monitoring the beacon both by ear and with a visual display on
spectran. When the CW started the normal display gave way to the CW signal
only and it appeared to be on the centre frequency of the DSB beacon signal.
I assumed at first that this was simply a new mode for the beacon. There
were a few CW characters and then the beacon resumed. The same thing
happened about 15 seconds later and then a couple of times more before LOS.
I then realised that this is the exact pattern of RS-30, 5 or six CW
characters at 15 second intervals. When I brought RS-30 up on my display I
discovered that RS-30 and Delfi have orbits that converge from opposite
directions once on each orbit and this convergence just happened to occur
over ZL on that pass. My next chance to have another look at this is the
2246 UT pass on 6 August but I would think this can be checked before that
on rev 1484 over Europe at about 0930 UT on the 6th August.

Hi Alan,
that is very strange. 435.315 is not a command frequency and is far
away enough of the transponder uplink and the actual command
frequencies so should not cause any trouble...
How did you find out that the CW on 145.870 came from RS-30?
Would be interested in your further observations!
thanks a lot and 73!

The Navy, actually the Johns Hopkins APL, designation was for the fifteenth
letter of the alphabet and because it was not an acronym, only the first
letter was capitalized, Oscar versus OSCAR.

I'm trying to set up my station's Doppler shift control. I have an
FT-847 and I've been working mostly with Satscape software because I
love the graphics display and ease of use. But getting it to accept
frequency changes thru the drop-down combo boxes (like changing AO7 from
Mode A to Mode B) is next to impossible.
Other software I've d/l'ed includes SatPC32, HRD, Nova for Windows,
Orbitron, and Predict for DOS. I like HRD the best but the current
build has a major defect in the 847 support. I've been less than
successful in getting any of the others to control the radio.
I'd like to hear from users of each package about how to interface with
the radio.
And please, no lectures about using Linux instead of Windows. It's not
an option.

Jim,
Note that Simon is working on an update and fix for the HRD satellite
module, and the preliminary screen shots look great. Stay tuned.
Otherwise, I have used SATPC32 for years with the FT-847 with great success.
.. how to interface with the radio.
Are you referring to the hardware needed? If so, all you need is a null
modem cable, a serial port, and an FT-847 with a bi-directional CAT. That
last is rather important, and applies to all but the first few production
runs. A USB serial port _should_ work fine, but some have had trouble and
needed to have the delay parameter in the setup tweaked. I had one which
would not work no matter what I did, but that was a special case.
If you could give us some specifics of the problem, there is a good chance a
solution exists.

Hi All
I will be working AO-51 and AO-27 from EM18,EM28,EM38, and EM48
for the next few days as I do a project for the Forest Service. HT and a
Arrow.
Most of the passes will be the PM passes. Please QSL to the MN address for
contacts
Thanks
