In addition to the other alternatives described by WA4SCA, Let me also
suggest another nice VNA (Vector Network Analyzer) -- the Mini-VNA and
Mini-VNA PRO made in Europe and available in the US from
http://www.w4rt.com/
and Gigaparts
(http://www.gigaparts.com/gpsales/1002/store.php?action=profile&sku=ZW4-MINIVN
A
<http://www.gigaparts.com/gpsales/1002/store.php?action=profile&sku=ZW4-MINIVN
A>
and
http://www.gigaparts.com/gpsales/1002/store.php?action=profile&sku=ZW4-MINIVNA
-PRO
<http://www.gigaparts.com/gpsales/1002/store.php?action=profile&sku=ZW4-MINIVN
A-PRO>).
I got my Mini-VNA PRO last year at Dayton from W4RT and I find it to be
a most interesting widget. It is a full 2-port VNA covering the entire
0.1-200 MHz range. It is intended to be used with a Windoze computer (my
Lenovo Netbook is more than adequate) and normally connects via USB. The
USB port provides DC power, either to run the unit or to charge its
internal LiPO battery.
It is battery powered and can also interface via a wireless Bluetooth
serial port. One nifty thing here -- you can put the entire VNA at the
feedpoint of an antenna (very useful with an HF wire), hoist it into the
air and measure the intrinsic feedpoint impedance with NO cables
attached, making all measurements using the wireless Bluetooth connection.
Another useful additional function is that the PRO has two independent
DDS generators, one associated with each port. They can be programmed to
use as separate programmable test oscillators.
The Mini-VNA and PRO are of German origin and marketed by Wimo:

more-e#minivna
<http://www.wimo.com/cgi-bin/verteiler.pl?url=instrumentation_e.html&p=minivna
-more-e#minivna>.
There is a nice writeup on the original Mini-VNA in the British magazine
Practical Wireless
(http://www.wimo.com/download/testreport_minivna_practical_wireless-dec-07.pdf
)
that describes use of the VNA.

Clint,
No wonder so many of us don't know when the sats are overhead...Look at all
those "slide rules!"

Hi all in Europe,
This week it is on over Europe.
I heard it this morning and again with AOS at 1645 UTC here
in Copenhagen.
The schedule will probably be on SA-AMSATs homepage shortly.
http://www.amsatsa.org.za/
Until it is there assume it is on during European passes.
Take a look at: http://oscar.dcarr.org/
AND please use normal FM modulation with the mike gain turned down until
your downlink sounds good.
Do not use the CTCSS tone.
Have fun.

Hi all,
Just had one of those rare opportunities with clear skies in the UK and a
wonderful sighting to remember..
The ISS and shuttle Discovery were both very visible - now undocked and
in transit west to east before going into eclipse 1924 hrs GMT
Being the last opportunity to see the pair like this will be something that
I will never forget.
Happy landing Discovery, Good Luck and well done to all of the team that
gave you such support.
