Sb: Shuttle Communications
02-Oct-84 21:23:37
There are several ways for people to listen in to Shuttle
communications during the mission.
If you have a shortwave radio, the Goddard Amateur Radio Club will be
rebroadcasting Shuttle communications on single-sideband on these
frequencies:
3860 kHz
7185 kHz
14295 kHz
21390 kHz
28650 kHz
(Frequencies obtained from WORLD SPACEFLIGHT NEWS, September 1984.)
Your shortwave radio must be equipped to receive single-sideband (with
a switch labeled "SSB" or "BFO") -- check its instruction manual if
you're not familiar with it.
If you have a scanner and live in certain areas, you may be able to
pick up air-to-ground communications from some VHF relay stations. Such
stations have about a 25-mile range.
In the Washington, DC area, try 147.45 MHz.
Around Houston, TX, check 171.15 MHz.
Near the Dryden Flight Research Center, Lancaster CA (near Edwards Air
Force Base), it's 169.4 MHz.
Also, the National Space Institute and AT&T will again be sponsoring
"Dial-a-Shuttle". Call 1-900-410-6272 to hear the astronaut
communications, or status and feature reports when the Shuttle is out
of range.
"Dial-a-Shuttle" costs 50 cents for the first minute and 35 cents for
each additional minute. This works out to about $10 a half-hour, but
it's better to refer to an activity schedule and call in when
something's happening.
The rates for callers outside the U.S. are the same as for a
long-distance call from that country to the U.S.
Finally, if you're really well off and have a satellite dish, you may
be able to pick up NASA Select Video off of NASA's contract channel.
The last I knew, though, this was on a low-power transponder, meaning
you need a sensitive dish and receiver to get a good signal (this one's
not as easy as the others).
So check Satcom F1R at 135 degrees west, transponder 13. If no joy
there, check Armed Forces Radio and Television Service on transponder
20; who knows, they may be relaying it.

{nOTES:{
1. fREQUENCY-SHIFT KEYED(fsk) WITH THE 'OFF' AND 'ON' PERIODS TRANSMITTED
ON TWO ADJACENT FREQUENCIES APPROXIMATELY 1 KhZ APART. tHE TELEMETRY FRAME
CONSIST OF A TRAIN OF RAPID SYNCHRONIZING PULSES FOLLOWED BY 15 WORDS
TRANSMITTED AT A RATE OF APPROXIMATELY ONE PER SECOND. tHESE WORDS ARE
PULSE DURATION MODULATED (pdm).
a VARIATION OF THIS BASIC TELEMETRY SYSTEM TRANSMITS ONLY THE 'ON'
PERIODS AS A KEYED CONTINOUS WAVE(cw). oTHERWISE THE FORMAT IS THE SAME
AS THAT FOR THE fsk-pdm.
2. fREQUENCY-SHIFT KEYING BACK AND FORTH BETWEEN TWO ADJACENT FREQUENCIES
APPROXIMATELY 1 KhZ APART. eACH FREQUENCY IS TRANSMITTED FOR EQUAL
DURATIONS SO THERE IS NO INFORMATION CONTENT IN THE SIGNAL. tHE TIME FOR
ONE COMPLETE CYCLE CARIES FROM ONE SATELLITE TO ANOTHER AND IS BETWEEN
1.4 AND 1.8 SECONDS. dIFFERENCES IN CYCLE-DURATION CAN BE USED TO
DISTINGUISH SATELLITES IN ORBIT SIMULTANEOUSLY.
3. kEYED cw SIGNAL CONSISTING OF A REPETITIVE SEQUENCE ON mORSE CODE
CHARACTER PAIRS, E.G. tf. tHE DASH OF THE t HAS TWICE THE DURATION OF THE
DASH IN THE f. t IS COMMON TO ALL RECOVERY BEACONS OBSERVED TO DATE.
4. cONVENTIONAL mORSE CODE CHARACTER GROUPS IN FOUR 7-WORD FRAMES EACH
PREFIXED BY THE IDENTIFIER, E.G. rs7. tHE WORDS OF THE FIRST FRAME BEGIN
WITH LETTERS k, d, o, g, u, s, w AND END WITH A 2-DIGIT NUMBER. sUBSEQUENT
FRAMES USE THE SAME SEQUENCE OF LETTERS PRECEDED BY i, a, m. wHEN THE
SATELLITE IS IN THE 'COMMAND' MODE, THE FOUR FRAMES START WITH THE LETTERS
e, s, u, w OBTAINED BY ADDING A 'DOT' IN mORSE CODE IN FRONT OF THE
CHARACTERS OF THE FIRST SET, E.G. i(..) BECOMES s(...), a(.-) BECOMES
u(..-), ETC.
5. apt TRANSMITTED IS SIMILIAR TO THAT FROM THE SUN-SYNCHRONOUS mETEOR 30
BUT IMAGERY CAN SHOW VISIBLE AND RADAR SWATHS CONTIGUOUSLY.
6. mODULATION-RATE OF 50 BITS/S. tHE DATA TO BE TRANSMITTED SELECTS A LOW
FREQUENCY AND THE RESULTING SEQUENCE AMPLITUDE MODULATES THE vhf CARRIER.
tHE DATA TO BE TRANSMITTED SELECT EITHER 3, 5, OR 7 KhZ PRODUCING SIDE
BANDS A, B, C AFTER MODULATING THE CARRIER. oNLY THE 3 AND 5 KhZ CARRY THE
BINARY INFORMATION. tRANSITIONAL ENCODING IS EMPLOYED, BINARY 1 BEING
REPRESENTED BY A CHANGE FROM 3 TO 5 KhZ OR VICE-VERSA. bINARY 0 PRODUCES
NO SHIFT IN FREQUENCY. tHE 7 KhZ TONE PROVIDES TIME SYNCHRONIZATION EVERY
SECOND.
tHE NUMBERS FOR THE NAVSATS GIVEN IN PARENTHESIS FOLLOWING THE kOSMOS
NUMBERS ALLOCATED TO THE SATELLITES BY THE sOVIETS.
7. iN THIS PULSED am TRANSMISSION, 4 MICROSECONDS-LONG PULSES ARE
TRANSMITTED EVERY 80 MICROSECONDS. tHESE PULSES DEFINE WORDS IN THE
TELEMETRY FORMAT. wITHIN EACH SUCH INTERVAL A WORD-VALUE PULSE IS
TRANSMITTED. iTS POSITION IN THE 80 MICROSECOND WORD-INTERVAL DEFINES
THE PARTICULAR WORD-VALUE TRANSMITTED. sUCH A SYSTEM IS PULSE-POSITION
MODULATED AMPLITUDE MODULATION (ppm-am). tHERE IS ALSO A SECOND MODE WITH
A WORD-INTERVAL OF 96 MICROSECONDS.
8. tHIS TELEMETRY SIGNAL CONSIST OF AN APPROXIMATELY 300 KhZ-WIDE fm
SPECTRUM WITH MOST ENERGY AT THE EDGES OF THE SIGNAL BANDWIDTH, INDICATING
A HIGH MODULATION INDEX. tHE MODULATING SIGNAL IS PROBABLY AN
AMPLITUDE-MODULATED PULSE TRAIN(pam). tHE NORMAL FRAME-DURATION IS 10
MILLISECONDS AND THE NORMAL FRAME COMPRISES 32 WORDS. iT HAS NOT BEEN
POSSIBLE TO MEASURE THE FORMAT-LENGTH TO DETERMINE THE AMOUNT OF
SUB-COMMUTATION USED.
tHERE ARE STILL ALOT OF sOVIET SPACECRAFT SIGNALS TO BE FOUND.
sEVERAL CLASSES OF SATELLITES HAVE ESCAPED DETECTION BY AMATEURS OF THEIR
RADIO SIGNALS. sOME OF THE kOSMOS MISSIONS i HAVE NO DATA FOR ARE AS
FOLLOWS:
