These are current as of this morning and seem to be accurate when
compared to the NASA mission status page.
UARS
1 21701U 91063B 11263.18833764 .01299762 11120-4 56017-3 0 6054

Until last night the altitude of UARS varied between 130-140 miles. As I
type this it is at 127 miles and appears to be gradually dropping. If you
have Ham Radio Deluxe v.5 add the 'Visual' sats group and you will see UARS
listed.

...and it will get a really close-up and personal view of the Upper
Atmosphere it was designed to study... :-)
Anybody know if there is still any life left in it? Any telemetry or
whatever?

At UniveseToday.com (http://www.universetoday.com) there is an article,
"Must See Video: Falling NASA UARS Satellite Observed While Still in Orbit."
It shows the uncontrolled tumble of UARS and gives more news about its
expected time to deorbit.

I do not know how accurate or up to date it is, but Heavens Above is

I have submitted for a tlm certificate my analysis of the voice telemetry
from Arissat-1 on certain orbits in September (when?I was present, hi).?
The dates of the?receptions in September?are in the analysis spreadsheet.
The MET is decreasing, I think this is because the satellite comes out of
eclipse and swithches on nearer the observation, as the orbit is precessing
I think the analysis shows that as the MET decreases, the IHU temperature
decreases, and the battery current increases (this is a lesser negative
number).
Put that another way, as the MET in sunlight increases, the IHU temperature
increases and the?circuit current decreases (greater negative number).
However I don't know why the circuit reports a negative current, or even if
the voice tlm is accurate. I'd be grateful for any comments.

Hello there.
Am looking for any reports of my Call being received Stateside during any of
the Ao51 passes. I only have a small humble station consisting of Ic-910 in
to a dualband vertical on my chimney and am considering buying a pre-amp for
70cm . If am not being heard Stateside on the West passes from my locator
Io85iv Ill maybe not spend money on a preamp?. I have had 2xcontact with
KB1RVT so we shall see. Please email me or send a message on here.
Thanks and 73's Kev

Hello,
We are looking for a UHF amplifier (430-440MHz) for a transceiver to go from
10 mW to ~ 75W. Most of the amps were are funding require a much stronger
input power than we can do. Note, it's a transceiver, so we want to be able
to receive through the system as well. This is for half duplex satellite
communication using a USRP radio.
Do you have any suggested amps?
Thanks,
--James, KF6RFX

James,
I do not see any amps that would meet your requirements. There are
several intermediate types that would boost the 10mw@xxxxxx to
enable you to use this low power driving another PA after that to
meet 75watts output. It seems that you should invest in a "normal"
mobile or handheld xcvr that would come closer to what you are
trying to accomplish. Go to Mirage amps website for some specs on
amplifiers to get a feel for what is commercially available.
73,
Dee, NB2F
