These are the frequencies Ron Parise (WA4SIR) will use on both voice and packet
(WA4SIR-0). Please note that the frequencies Ron will be listening for
stations ARE DIFFERENT than the one he will transmit on. This is a very
important fact to understand. Ron will transmit to earth (downlink) on a
single frequency: 145.55 MHz. He will listen for stations transmitting to him
(uplink) on the other frequencies listed. This "split" operation is used
quite successfully by DXers and previous shuttle astronauts when operating in
an environment where large pile ups are expected.
The first pair of frequencies (noted as primary) employs a standard -600 KHz
split used by repeaters. This was done so that communicating with SAREX could
be accomplished by Hams using standard FM transceivers. If Ron finds that the
receive QRM becomes unmanageable, he may listen on the alternate frequencies
listed. In North America, the lower section of the FM repeater bandplan
extends as high as 144.90. This is why the uplink frequencies only extend
down to 144.91 MHz.
There will be no simplex operation with SAREX on either voice or packet.
Although packeteers are not used to operation with a TX/RX offset, in this
case, it is the only way to connect to SAREX. If you transmit on 145.55 MHz
the only people who will hear you are those other Hams in your area trying to
contact SAREX (You will most likely become an instant celebrity, but not
in the positive sense of the word!).
There should be about 3 KHz of Doppler shift due to the orbital velocity of the
Columbia spacecraft. By limiting the deviation of your transmitter to 3 KHz,
Ron's receiver should have little trouble capturing your signal.

NASA Affilated Radio Clubs & ARRL To Provide STS-35/SAREX Mission Updates
Radio amateurs and Short Wave Listeners (SWL) will have many opportunities to
listen to all the onboard activies from the Shuttle Columbia as the astronauts
perform their planned scientific experiments and investigations with the
ASTRO-1 payload. The following list of frequencies will provide a "spot" to
listen and receive pertinent information on the progress of STS-35 and the
Shuttle Amateur Radio Experiment (SAREX). W1AW will provide SAREX Mission
updates during its daily bulletin schedule.

Sorry I missed you last night. I was getting tired and couldnt stay around.
I will keep my eyes open for a 3 1/2 inch drivee for you. The last
computer show I went to in Woburn, you could find a drive for $30. I dont
know when the next show is though.
Talk to you later>>> Ken
