Fun around the camp fire

Post by djw » Tue Jan 24, 2006 9:16 pm

*Click here*
Suitsat-1 (also called Radioskaf or Radio Sputnik in Russian) mission activities will be conducted on the amateur radio (ham radio) frequencies, a bit above the FM broadcast band. The voice signals can be picked up with ham radio receivers and FM VHF (Very High Frequency) scanners—like police-band scanners.
Don't need a ham license to listen in. :wink:

It should have been kicked out of the ISS a few minutes ago. Next pass over the US won't be until tomorrow morning.

I fired up my SSTV setup and will be listening for the images it's supposed to send. Right now the SSTV is still monitoring 14.230 HF for practice but tonight I'll swap the cable to the 2m radio for the suit. Any SSTV images I capture are posted here:

Fired up my gear and put it into auto for the 2am pass.

Maybe or maybe not.

Word is the batteries failed almost immediately. Some reports of a VERY faint signal but the people hearing that have big antenna arrays and specialize in weak signal work.

So it's not looking good.

Just woke up to see what's going on and the wife turned down the station.

:oops:

No biggie, got an hour (give or take) to go.
However with Jason's report we'll see what will be.
I do have a preamp for 2M, just not out on the antenna
like me 70cm.

From Spaceweather.com:
SUITSAT IS SILENT: Space is cold--apparently too cold for SuitSat's batteries. The Earth-orbiting spacesuit stopped transmitting shortly after it was thrown overboard from the International Space Station on Feb. 3rd. Probable cause: lack of power.

This doesn't mean that SuitSat was a failure. The experimental satellite was "launched" to answer questions such as "Can a spacesuit-satellite function without internal temperature controls?" The answer, apparently, is no. Next-generation SuitSats will take this into account.

SuitSat will continue to orbit Earth for weeks, spiraling slowly into the atmosphere. Stay tuned for information about seeing SuitSat in the night sky.

On the AMSAT list, one guy indcated that a sunlight pass might warm up the batteies.

Time to go back to bed.

A few more reports of weak reception....but I doubt the sunlight pass will help that much - it's still only in sunlight for half the orbit. Which means about 30 minutes total. It looks like it will come into sunlight about 16 minutes before passing over the west coast. So that only gives the batteries 16 minutes to warm up.

I know they kept the suits temp controls off to save battery power. But what good is saving battery power if the batteries go beyond their physical limits :D Seems like some poorly thought out engineering on that part. Before "launch" the big concern would be that it would be too hot for the batteries. So hearing that they're frozen was kind of surprising at first.

WooHoo! :D

The last pass at 10:25 local.

Heard a bit of CW.
Then the SSTV kicked in, but no picture.
A mans voice
A little girls voice (somethign about a one?)
A mans again

Some more SSTV

Then two local yahoo's started chatting on the freq. :?
They were promply told not to xmt and get off the freq,
by some other gentleman. :twisted:

Recorded the pass on MMSSTV, an 11K file if anyones interested.

Very cool Dwayne, were you using your eggbeater?

I tried with the J-pole I've used to talk to the ISS before but other than what sounded like a few hints of SSTV deep in the noise I didn't hear anything :(

Oh yeah...forgot about that.

Still impressive considering that some guys with EME arrays are having a hard time hearing it!

The bummer about the whole thing is, I was thinking about all those people out there with scanners could at least listen in. Dana heard about it from the school Dist, I'm sure that there's a lot of students tuning in.

Bummer again. :(

At least it was tried, no guaranties in space. 8)
