David. what the Russians lack in our technology they make up for in their
engineering and their practical approach to events. A launch at Baikonour,
particularly of a Soyuz (crewed) vehicle is a wonderful event. Flying with
them (and their airplanes) is likewise a fun event. Unlike our "Vomet
Comets" the Russians wear parachutes during microgee flight and at times are
known let those who want to to "jump" after the event.
Of course then there are the winters!

Hi all,
today a Multi Carrier rocket was launched from Baikonur carrying a few
satellites, including Tatiana 2(Universitetsky 2) and Sumbandila into orbit.
Found Universitetsky 2 (Tatiana 2) transmitting Data (and occassinally CW
also) on ~435,365 MHz. this evening at around 19:20 UTC.
Signal was quite strong but with some heavy fading now and then, probably
caused by the satellites rotation.
Regards, Nils

Glen,
Actually, AO-7 was placed in the narrow-band (CW/SSB) subband back when it
was launched. AS I recall a waiver was sought to do this. So AO-7 is, in
fact, in the wrong frequency allocation for satellite operations. Perhaps
Tom Clark or one of the other old hands that were involved when AO-7 was
built/launched can better state this (I was a member of sbms that built the
2.3 GHz transponder that was never allowed activation).
As far as attracting new satellite operators, there is an even chance since
the operator already is in possession of CW/SSB equipment that is required
for AO-7. Basically, they would need proper antennas and learning about
tracking issues (times, freq. Doppler, etc.). Also that the input is
inverted so one tranmits LSB to hear USB. Most of the weak-signal group
(CW/SSB) are pretty savy bunch, so it remains whether it would interest
them.

Subject: [amsat-bb] Re: accidental satellite ops
The primary problem is that the OSCAR VII inputs are now in the weak signal
portions of the "band plans". With the proliferation of FM activity the
weak signal portions have been compressed. It is unrealistic to even think
of "blaming" the weak signal operators for interfering with OSCAR VII
operations. Remember, OSCAR VII is 35 years old and was not expected to be
in service for more than just a few years.
One should just be happy that OSCAR VII is still usable and work around the
occasional situation with unintentional interference. Besides, there are
not that many contests on the VHF and UHF bands and most of the time there
is little activity in the weak signal portions of 2-meters and 70 cm.
As for garnering additional satellite operators that is definitely a
possibility. However, I don't know how many new operators would actually
be recruited.

Graham,
... think this was RS-22. I heard the CW beacon as well (very strong).
I never read about a 70cm beacon of Tatiana-2. In my opinion they didn't
publish any frequencies...

I went back in my copies of the AMSAT Newsletter (I have virtually all of
them starting with Volume I, Number 2, dated October 1969 - I joined AMSAT
the 2nd month of the organization's existence) and the only mention of a
waiver was that due to the control requirements that a waiver was requested
for OSCAR I through OSCAR VII. Volume V, Number 1, March 1973, page 19,
describes the frequency selection for the OSCAR VII transponders and the
mention is made that the life expectancy was 3 years. But, there was no
mention of a waiver due to the frequency selection.
Volume V, Number 4, December 1973, has a lengthy article on the capabilities
of OSCAR VII. Again, no mention of a waiver because of the frequency
selection. On page 18 of that issue there is an announcement of Notice of
Inquiry from the FCC concerning rules for the newly proposed Amateur Radio
Satellite Service.
Volume VI, Number 2, June 1974, has AMSAT's official response to the Notice
of Inquiry by the FCC starting on page 8.
Remember, before the establishment of the Amateur Radio Satellite Service
there was nothing in the FCC regulations concerning the frequencies even
suggested, let alone required.
These days 47 CFR Part 97 Section 97.207(c)(2) specifies, among other
frequencies, 144 MHz to 146 MHz and 435 MHz to 438 MHz as the allowed
frequency segments for satellite operation. But, prior to either late 1974
or early 1975 there were no specified frequencies for satellite operation.
Of course the frequency range of 144 MHz to 146 MHz definitely encompasses
the "weak signal" portion of the 2-meter band. The 435 MHz to 438 MHz
segment is well above the present "weak signal" portion of the 70 cm band.
It is my opinion that the segment around 432.150 MHz was chosen because the
vast majority of operators that had 70 cm capabilities were operating very
near this segment and therefore no additional transmitting equipment would
have to be acquired. Also, most 432 MHz operators also had 2-meter
capabilities and could easily "hear" the downlink.

Actually, AO-7 was placed in the narrow-band (CW/SSB) subband back when it
was launched.? AS I recall a waiver was sought to do this.? So AO-7 is, in
fact, in the wrong frequency allocation for satellite operations.? Perhaps
Tom Clark or one of the other old hands that were involved when AO-7 was
built/launched can better state this (I was a member of sbms that built the
2.3 GHz transponder that was never allowed activation).
As far as attracting new satellite operators, there is an even chance since
the operator already is in possession of CW/SSB equipment that is required
for AO-7.? Basically, they would need proper antennas and learning about
tracking issues (times, freq. Doppler, etc.).? Also that the input is
inverted so one tranmits LSB to hear USB.? Most of the weak-signal group
(CW/SSB) are pretty savy bunch, so it remains whether it would interest them.

The July/August 2002 AMSAT Journal has a copy of the waiver on page 25,
dated April 19, 1974.
At the time of the construction of the satellite, there was no separate
amateur satellite service. By the time of the launch, there was, and it
was 435-438 only, hence the waiver.

Check out FAR Circuits, as well... I can't remember what I paid to have
them make the FOD-Track boards several years ago (which are now in their
regular lineup...), but I just had to send a negative of the board & a
reasonable (I thought) fee, and the deed was done.
