Does anyone have information on using 50mhz crystals in a RC
transmitter that is presently using 75mhz crystals? The user
is a licensed ham but we're jsut wondering if the 75mhz RC
transmitters can handle the 50mhz crystals.
Thanks

Prelaunch Keplerian Elements:
These are the Keplerian elements for STS-64 mission, rotated to the
current planned launch time of Sep 9 at 20:30 UTC. The JSC-005 epoch
is at the start of orbit 5, after the trim burns on orbits 3 and 4. The
negative drag fit was required to match the design trajectory because there
is a 6.5 fps trim burn on orbit 28. The phasing and circ burns on orbit 99
lower the altitude by about 8 n.mi, so the second element set JSC-006 is
required after that. These Keps are provided by Gil Carman, WA5NOM
at the Johnson Space Center ARC.

[G3RUH/DB2OS/VK5AGR]
RS-10: In last week's OSCAR Status Reports NO1R reported that he has made
some very spectacular contacts with his very modest Mode-A station
arrangement. His station set-up includes a Kenwood TR-751A at 25 watts
into a AEA Isopole up about 35 ft. His receiver is the Realistic HTX-100
into an inverted-vee up about 30 ft with an Advanced Receiver Research 10M
preamp. This week NO1R reports that he has just received a QSL from Andy
Mironov at RS3A confirming my RS-10 Robot QSO in April. Andy also writes:
"I will be glad to have any info abt your work via RS: your DX? PSE send
by post or packet. 73 Andy" The packet address is for Andy is:
RK3KPK@RK3KP.RUS.EU [NO1R]
AO-13: N7RYW would like to pass on a note about the Mode-S transponder. He
has noticed that there is one station who continually sweeps the uplink,
looking for his downlink signal. This is fine normally, N7RYW says, but as
this station starts to increase his power far in excess of what is needed
when he is unable to find himself. The net effect of this is that other
stations can't hear themselves either because the AGC on the uplink receiver
has reduced its sensitivity to compensate for this strong signal. This has the
effect of reducing the AGC affects EVERYONES, making it impossible to even hear
their own signals! N7RYW has tried to respond to this station CW CQs when it
finally does settle down (over 20 minutes one day!), but it does not respond
to N7RYW's SSB call. N7RYW says he doesn't have a key, and doesn't want to
install one just for just one single lid! All of the Mode-S users N7RYW has
talked with are well aware of the power limits for uplinking with this one
exception. N7RYW will not single out this person with their callsign, so he
hopes a call to him in this way, with as much information as possible, without
the call, will get his attention. This problem is ongoing, and serious. A
station recently was attempting their first QSO on Mode-S a few days ago, and
could not get it done due to this over-powered signal wiping out the trans-
ponder. This is definitely NOT radar, which does not start sending
CQ CQ CQ DE *****! While it won't help the excess power problem, this item may
help people "find themselves." N7RYW has found that the Mode-S transponder's
actual downlink appears to be 2400.735 MHz to 2400.765 MHZ, up 30 kHz from
those published. N7RYW does not own a signal source with that high of frequency
to verify this, but the UO-11 beacon passed zero Doppler within 1 kHz of the
published frequency, so N7RYW would like to hear if anyone else has found those
frequencies to be more accurate so he can verify and notify!
[N7RYW@teleport.com]
KO-23: N7RYW reports that KO-23 is now back in operation after an OBC crash.
The groundstation control elected to do a data dump to try to find the
cause of the crash, so it took a few extra days to get the OBC reset.
[N7RYW@teleport.com]
KO-25: KO-25 is back in service. Both KITSATs were down at various times
for output power tests. These tests appear to be over for now. N7RYW has
noticed that when either one is down due to a crash, a peculiar tone is
emitted on the transmitter. If you are getting a good signal level, but no
data, turn up the volume and listen for this tone. It may save you some
head scratching later! Also, on the two KITSATs, the control station
usually puts out a notice when one of the sats will not be in regular
service. They are usually short notices, and originate from HL0ENJ,
so it might be good to mark all messages from this station for automatic
downloading in your select files. [N7RYW@teleport.com]
UO-11: The 2401.5 MHz beacon was been heard by N7RYW twice with an unmod-
ulated carrier. On the first occassion he had the polarization set at LHCP,
and it was just barely audible. Later he changed to RHCP and the signal was
very strong. This polarity change was done on a 6' dish with a horn type
feed with dual probes fed 90 degrees apart, much like a crossed dipole.
[N7RYW@teleport.com]
AO-16: AO-16 is up and running well. [WH6I]
The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
OSCAR status reports. If you have a favorite OSCAR which you work on a

Aries or ARES?
Aries is available from Ashton ITC for $89.00 (when last I asked).
PO Box 830 Dandridge TN 37725 or phone 1 (617) 397-0742
It is a contest and logging program that includes the software to
run Icom radios with the CT-17 cntroller.
ARES is the Amateur Radio Emergency Services psuedo-bbs package. I
believe it is available from the ARRL and/or TAPR.

Exactly how many newborn babies are capable of passing an amateur license exam?
More to the point, exactly how does the fact that this license is issued at
no charge (it's really paid for with tax money) justify rotten service?

It *never* fails to amaze me how people can read something and be
completely incapable of understanding what they have just read.
Clueless Joe, that's you're new name on this group. How many people own
Icom radios? How many require service? How many phone calls does Icom have
to deal with from people that can't be bothered to read their owners
manuals? And you want Icom to hire extra people full time just so that
when *YOU* call, you might not have to spend a few extra dollars or be
inconvienced by having to wait a few minutes?
I'm sorry if it offends you that I have money to spend on equipment, or
especially if I choose to spend it on phone calls, shipping materials
or service manuals.

Don't know about a reflective radio telescope, but amateur radio (ham)
operators have frequently bounced their radio transmissions off the Moon.
Usually using VHF (30 to 300MHz) or UHF (300 to 1000 MHz) frequencies.
These frequency bands almost never bounce off the ionosphere, so to get
long distance communications (intercontential), hams bounce their signals
off the Moon. It ain't easy, they need high power and directional
antennas and low noise sensitive receivers. It's called "EME".

Well, here comes my $US 0.02 worth ( ~$AUS 0.03; or ~UKP 0.01 ) ...
I've seen quite a few postings on this one. I speak / write as someone who
learnt code from three methods:
1) tapes;
2) on-air copying of 80 m ham traffic (fairly tame - all vk novices tx'ing
nice & slow), marine traffic lists (callsigns were sent twice), and
wx reports; and
3) using code practice oscillators & keys.
I passed my 5 wpm rx test with 1 error, and my 10 wpm with none! I
subsequently became vk4vle in late 1981, and upgraded to vk4bmd within 3 months.
I remember my first *real* cw qso - it was on 20 m. I don't think any amount
of preparation on my part would have made it any easier! I'd had *tame*
qso's on 10 m across town, but you can imagine just how tame that was! In that
qso on 20 m, I was suddenly hit with the full gamut of abbreviations,
interference, fading, noise, the requirement for a near-immediate reply
(otherwise the guy started calling back to see if I was still there!), and just
sheer nervousness. It was what one would call a template qso.
After my first few nights on 20 m, I started to find things a lot easier. By
the end of the month my speed had increased, I had developed the "human
ear adaptive filter" technique needed to wrest the wanted signal from the 3
others qrm'ing, could start to compose a reply while copying (hard copy,
too) the incoming traffic, and could also send in the "off the cuff" style so
very important to conversational cw.
My first three months as a full call in 1982 were filled with cw qso's ...
why? Two reasons:
1) I enjoyed using the medium (yes, the "hollywood" bit initially
applied!) - especially in conversational mode; and
2) I'd borrowed "my" first all-band rig off an old ham friend - a
dedicated cw op - and he "conveniently" failed to provide a microphone
when I picked up the rig!
Some of my most memorable qso's have been on cw - the majority of them to those
folks across the water in w / n / k land. They were all amazed that I
could reach them nightly on 20 m using 10 - 20 W and a dipole. It was fun!
Now, I'm not on air much. But, I want to get back to it all soon - especially
when I get back to vk . I'm using the PC and cw program to get my copy speed
up, and am finding that it *will* change my operating technique. I'll
definitely be using a typewriter or keyboard to copy the traffic, but NO pc-
driven code reader! I'll try to stick with my old PMG No.2 key, but I *might*
go to an iambic, or something along those lines.
73's all

QEX is a subscription magazine published by the ARRL. Try sending email
to:
qex@arrl.org
I don't know if you can buy single back issues.

How about when you retire from the United States Air Force after 20 long years,
and then go to school for six months <looking for work all the while and not
finding it> and then end up working at your favorite ham radio store...
Happened to me!
