It looks like it has some nice features including only downloading
only updates instead of all the data and a nice systematic way of
downloading decay information (which is new I think).
The one thing I am trying to figure out how it works is downloading
updates when one has multiple clients. Is the last login stored on the
server or on the client? Will I need to create separate accounts for
each piece of software or merely maintain a cookie file?
On a related note, how widely available is space-track data? I realize
amsat, celestrak, and others have agreements to redistribute data. But
what do the restrictions to non-US persons look like?

I have been working with some of the new low cost RTL2832U+E4000
dongles that are flooding the market. It appears that they are
designed for the digital TV market in some countries outside the US.
They cost about $20. They usually come with an antenna and a remote
control. The antenna and remote are useless but the dongle does work.
It has a PAL antenna connector which is not a problem since an adapter
are available at Radio Shack.
It takes a bit of digging around to find the drivers. There was some
sort of license fight between a couple of "open source" developers
which makes it a bit more difficult than it should be. I have one
'working' with HDSDR. It is still a little funky changing frequencies
with the 'FreqMgr' but it is early days. The performance is the same
as the FUNcube. There are quite a number of different chipsets in use
so buyer beware.
If you like hunting for working drivers and ExtIO programs and
tinkering these E4000 dongles are for you. IMHO the FUNcube Dongle is
still the best bet for the rest of us. My FUNcube has been sitting on
the shelf for quite a while as it does not perform as well as my
receiver even with the help of a SSB mast mounted pre-amp and cavity
front end filter. I was talking with someone on FO-29 and they
mentioned they use theirs as just a panadapter. I dug my FUNcube out
and it does work well as a panadapter (no connection to the receiver
required). Very handy on those rare occasions when there are more than
zero people on the linear sats.
SDR-Radio v1.5 works well with the FUNcube . Very nice work by Simon.
I do miss the picture of him and his dog when the SDR-Radio program
boots up.
Very interested in seeing Howards "FUNcube Dongle PRO-PLUS". I hope
the PLUS is not a price increase. In an attempt to find out what it is
before the official release I searched the net and came up with this
gem from 2010 on the http://www.funcubedongle.com 'Ordering FAQ' page.
Be sure to check out the link.

Thanks to all the Europeans who manage to keep out hobby alive and up to date.

Hi,
Cleaning the shack, and I have a spare FCD Pro V1.0 SN 188 for sale. This
is first generation and does not provide +5V on the antenna as do the V1.1
units.
It is in perfect electrical and mechanical condition, and used only the
shack. $80 including shipping to North America.
Please contact me off list.
73s,

I contacted the YW5B in 24.945 and they have problems to be on SAT, so will
be in another expedition.

I have been using external (mast mounted) preamps for 2m and 70cm from ARR
with my TS-2000 for 2 years and quite happy with their performance. These
RF-switched preamps just work always and they're weather proof so virtually
no maintenance is needed. Note that they can only handle maximum 160W RF,
which is good enough for me. http://www.advancedreceiver.com/page10.html

I've had phenomenal success with the SSB preamps over the last 25 years.
I have one for both 2 meters and 70 cm and if I had anything worth
mentioning on 6 meters for an antenna I would have one there as well.
Prior to that I used Landwehr.
For my EME station I am using a DB6NT receive-only, only because at the time
the Deutschemark ( or Euro ) was cheap and I could get the DB6NT cheaper
shipped from Germany than I could get an equivalent SSB receive only here. I
have no regrets, the DB6NT is a thing of beauty as only German workmanship
can make.
I see that ARR is now making an rf-switched preamp that handles some power
now too, but I'd stick with the SSB if I were you, only because they will
handle up to 700 watts if you sequence them; 200 RF-sensed.

that with the particular preamp and xcvr I have a sequencer is needed to
ensure dx is removed from the coax before rf is introduced. I think the
easiest solution is to get a different preamp once I get my icom repaired. I
could also swap it with the mirage I'm using at home with the 847 which I
think is immune to rf or is switched. Unless you have an icom xcvr their
preamps are a bad purchase.

The IARU International Amateur Radio Satellite Forum will this year be held
in conjunction with the AMSAT-UK Colloquium which takes place in Guildford,
England on the weekend of September 15-16.

The Huffington Post reports on the imaging CubeSat SkyCube that will be
utilizing a network of 915 MHz ground stations operated by the US Navy, the
Boeing Corporation, and the University of Utah for CubeSat projects.
Images taken by SkyCube will be transmitted by a 57.6 kbps modem that was
developed for CubeSats using the 915 MHz band.
