Russian-built Soyuz rockets will send up the satellites in batches of two from
October 2012. By early 2014 it is anticipated there will be 16 satellites in
orbit, see

Hi Andrew,
Theoretically, yes. Realistically, probably not.
If the server software is available, and be made to run on typical
PC CPUs, the answer is yes. I can't recall if the satellite/server
side of the software is available or not...search around. The client
side software was called PB
Different CPUs on different spacecraft, mostly running a custom
spacecraft operating system (SCOS). Google 'bektek' and 'pacsats'
and you can find lots of information about the satellites--old and
new.

Hi all,
Yes very pleased to hear the news and was about to post the information to
the BBs.
Many congratulations to Sir Martin Sweeting and his team at SSTL - a very
just reward for all of the hard work and efforts by all involved. The news
is also published in full on the SSTL web pages.

will be in the orbit?
Please take a look to the document below:
It's unlikely you will notice any significant difference.
The band is already shared with many other users and a spread spectrum signal
will just raise your noise floor slightly,
assuming that one of their satellites is within your beamwidth.

I agree with all you have suggested, Mark. I too had questions about
power output on the 910. I discovered that the power to the radio was
the culprit. Before you send it away, check and make sure you have #10
cables to the radio and your power supply delivers the correct voltage

Alas, my search is back on again for a service manual (not the instruction

in advance

Hi Greg
I'm confused. It seems to me that the place when Doppler is zero is when the
satellite is about half way through the pass. This is when the Doppler goes
from positive (coming at me) to negative (going away from me). It seems like
this place would be the time of closest approach (TCA)

I think part of the subject that confuses most of us (me included!) is
that while at TCA the offset is 0, the RATE of change on either side
of TCA is higher than at AOS or LOS.So, the actual frequency
offset is BIGGEST at LOS and AOS, but the rate of change is slow (it
doesnt' change much).
Correct

You call it the other issue but it is the only issue. They do not
give a tinker's damn if they interfere with us (and I suspect they
won't) but the ability to sell receivers with CRAP for front ends (in
terms of dynamic range, IMD, etc.) making it cheaper to manufacture is
severely
Hi Alan,
I have some questions regarding HO-68..
Would it be possible to reschedule HO-68 for Australia and New Zealand
at more appropriate times around the 22:00UTC passes ?
Its currently not operating , in our corner of the world, around the
22:00UTC timeframe, that is morning for us, and
FO-29 should come out of the eclipse soon.
JARL still are making an effort hard the examination use.
A operating schedule will be announced soon.
