PY2BJO Thanks Those Who Brought DOVE Back On-Line
As reported previously in the AMSAT News Service (ANS), DOVE is back on 2M
with the DOVE control team continuing their efforts to restoring it to
voice operations.
Junior de Castro (PY2BJO), of BRAMSAT, the Brazilian AMSAT group, which
sponsored the DOVE satellite has the following to say regarding the
satellite's recent return to 2M.
"After a long time DOVE is back again on 2M at 145.825 MHz. This project
was created to provide an extremely simple way for those not familiar with
satellite communications, especially those new to amateur radio, to take
part in this exciting phase of our hobby. DOVE is finally beginning to
live up to it original promise.
After its rebirth, we at BRAMSAT are receiving many E-mail messages and
letters. Up to now they total 328, from 45 countries. We are happy with
this response, but we will be even happier when DOVE again becomes the
popular satellite that we always knew it could be."

AMSAT Operations Nets are planned for the following times. Mode-B Nets
are conducted on AO-13 on a downlink frequency of 145.950 MHz. If, at the
start of the OPS Net, the frequency of 145.950 MHz is being used for a QSO,
OPS Net enthusiasts are asked to move to the alternate frequency of 145.955
MHz.
Date UTC Mode Phs NCS Alt NCS
12-Dec-93 0435 B 180 W9ODI WB6LLO

Any stations with information on current events would be most welcomed.
Also, those interested in discussing technical issues or who have questions
about any particular aspect of OSCAR statellite operations, are encouraged
to join the OPS Nets. In the unlikely event that either the Net Control
Station (NCS) or the alternate NCS do not call on frequency, any
participant is invited to act as the NCS.

AO-13 will experience another partial solar eclipse on 1993 Dec 13 [Mon].
It sees the Moon eclipse the Sun from 10:09 - 10:59 UTC with a maximum 53%
obscuration at 10:34 UTC. This is Orbit #4211 MA 73-92. The encounter
will be "visible" on the telemetry to stations throughout the USA and
Japan. Reports would be appreciated. Stations who observed this spectacu-
lar eclipse of Dec 13 will know what to look for. Eclipses of the sun by
earth commence on Dec 07 [Tue] and continue until Dec 24 [Fri]. The
eclipses are, of course, total. The maximum lasts 2 hours and 16 minutes,
and is the longest AO-13 has ever experienced. The telemetry during these
outages is very interesting, particularly the spacecraft temperatures; some
reach -40 C. The Mode-B transponder will be OFF from MA 95 to 180 during
this two week period. [G3RUH/DB2OS/VK5AGR]
FO-20: The following is the FO-20 operating schedule:
Analog mode: 01-Dec-93 08:43 -to- 07-Dec-93 7:16 UTC
15-Dec-93 07:41 -to- 22-Dec-93 8:05 UTC

Subject: API for HAM CALL
To: info-hams@ucsd.edu
-> I talked with the Buckmaster folks about this at Dayton last year. They
-> seemed lukewarm to the idea of an API, and to a Windows interface, but
-> had no real commitment to do it from what I heard. The data is encoded
-> in some wierd way, and they seem to want to keep it private.
-> The QRZ! disc is cheaper and better (though it is domestic only).
I have might doubts about how complete the Buckmaster international CD-ROM
callbook is. I ran through a few local call-signs, at least two did not
appear - even though both calls have been issued many years, no change in
address and not "particulars withheld ...". Try GM0FRG and GM4PWR.
I mentioned previously the LOOKUP option seems to have some bugs.
I agree that the QRZ! ROM is better - for US calls only unfortunately.

While reading the scanner newsgroup, someone mentioned
listening for GPS birds. I'd never thought of that, but
it seems kind of neat. The freqs mentioned are 1575.42
(out of my range) and 1227.6 - but I've tried the 1227 freq
(in fact searched all of 1227 - 1228 and don't hear anything
(also using a not so good antenna)) - can anyone say WHAT you
should hear from one of the sats? What mode/bw would be best?

Two possibilities, Matthew.
1. "since it is possible that I may be faced with an emergency...."
Make sure you are looking at this from a realistic viewpoint. How many
emergencies have you had in the lsat 10 weeks?
2. The best way I can think of to identify yourself would be to say that
you are a civilian that is using a modified ham radio that a sheriff
friend of yours confiscated in San Diego and gave to you. Then leave the
area before details can be examined. Let them sort it out.

To: info-hams@ucsd.edu
Well, my Dad has asked me if he can use my Amiga with it's new digitiser
(Vidi-Amiga 12) to send Slow-Scan TV pictures over the airwaves.
At the moment he's using my old Sinclair Spectrum, but the Amiga can
produce nicer looking graphics and doesn't take five minutes to load
the program and another couple of minutes to load a picture from tape.
You can get Spectrum emulators for the Amiga, but there's no mic socket
on the Amiga to use with the program!
Anyway, any information on programs, any circuits etc.. appricated such exists -
I don't know whether I'll fully understand it but I sure my Dad will.
Thanks,

Call me a bigot, but I expect Amateurs to have at least one reference
book available (not necessarily belonging to him/her); at least, the
one they used to study for their ticket...
Again, asking "how do I calculate the SWR" here is akin to asking "what's
the pinout of a 555" over on sci.electronics (where all too often questions
like that are seen).
Of course, if the person who posed the question in the first place is not
an Amateur (I've lost the original) then naturally I withdraw the remark;
however, the Net is not a substitute for leg-work.

CHRISTMAS ISLAND. An operation by VI9XN and VK9XO is up and running
from this Indian Ocean island and expected to be QRV through
December 15. QSL VI9XN via W5KNE, VK9XO via VK4CRR.
GAMBIA. C50BI has been quite active during the past week. Check
14010 kHz at 0120z and 7008 kHz at 0530z. QSL via 6W6JX.
JOHNSTON ISLAND. KH3/NH6HX has been a good catch on 80 meter CW the
past few days. Try 3515 kHz at 0735z and 3529 kHz at 0830z.
MACAO. XX9AS was worked on 14010 kHz at 1510z and 7009 kHz around
1400z. QSL via KU9C, 1992 CBA or later.
NAURU. Ron, ZL1AMO, is operating /C21 and has been very active on
14025 kHz at 0130z and 24902 kHz around 2030z.
SABLE ISLAND. CY0SAB was worked on 3797 kHz at 0200 and 1100z. QSL
via VE1CBK.
SAINT MARTIN. A serious all band, CW/SSB multi operation from
French Saint Martin is scheduled to start today and run through
December 8. Keep an eye on your PacketCluster screen. QSL via
W2QM.
TONGA. Paolo, IV3UHL, will begin operating from here starting the
1st of December through January 31st. His call sign is unknown at
this time. He may also do some IOTA island hopping around Tonga.
Listen for his CW at 5 kHz up from the band edges. For SSB, try
3760, 7095, 14260, 21260 and perhaps 17 and 12 meters. QSL via
IV3UHL.
LEBANON. Erik, SM1TDE, currently working for the UN, will be active
signing /4U until May 1994. He was heard on 24892 kHz around 1245z.
SUDAN. According to Abdusalam, an operator of ST0K, this station is
the first official club station and is located in Khartoum, the
capital city of Sudan, and not in Southern Sudan as some had hoped.
Abdusalam also reports that the ST0 prefix will be used only for
club stations. Listen for ST0K on 18085, 21001 and 24895 kHz
between 1230 and 1430z. QSL via Box 617, Khartoum, Sudan.

I dunno. I betcha the engineer at that BC station understands the meaning
of rectification and/or fundamental overload. And he may not even have a
2x2 call-sign.

SB PROP ARL ARLP048
ARLP048 Propagation de KT7H
Conditions have been mostly quiet over the recent period, with low A
and K indices, and the solar flux repeatedly flirting with the 100
level. Geomagnetic storm warnings were being issued mid week before
this bulletin was written, but conditions should quiet down by the
weekend.
Solar flux should dip down to around 90 next week, and then go up
over 100 by mid month. There are no more disturbed periods forecast
for the near term, with the possible exception of some slightly
active geomagnetic indices around December 15.
The author is again receiving mail requests for explanations of some
of the terms used in this bulletin. Don't forget when writing to
include a self addressed stamped envelope for a reply. The address
is 5519 12 Ave NE, Seattle, WA 98105. The packet radio address is
KT7H at N7DUO.WA.USA.
A good source for basic information is the Propagation section in
any recent copy of the ARRL Handbook. What most users of HF radio
hope for is a higher solar flux, indicating more ionizing radiation
from the Sun, and higher usable frequencies. When solar flares or
coronal holes on the Sun produce protons, these recombine with
electrons in the ionosphere and lower the reflectiveness, as well as
cause absorption on polar paths by disturbing the Earth's magnetic
field. Higher A and K indices, as noted on WWV broadcasts at 18
minutes after each hour, are indicators of these disturbed
conditions.
When the K index, which is updated every three hours, is lower than
three, conditions are usually quite good. When the daily A index is
lower than ten, this indicates good conditions as well, but for the
previous day. K indices of greater than three or an A index higher
than twenty is a general indicator of poorer conditions.
Sunspot Numbers from November 24 through December 1 were 78, 61, 52,
55, 75, 92, 101 and 100, with a mean of 77.8. 10.7 cm flux was 100,
97.2, 93.2, 90, 93, 93.8, 103.7 and 108.6, with a mean of 97.4
