Has anyone located a driver for the LVB Tracker internal USB to serial
port adapter on Windows 7 x64?
If not, has anyone reverted to the serial port connection on LVB Tracker
and used an external USB to serial port adapter successfully with
SatPC32 on Windows 7 x64?
I have an Edgeport multiple USB to serial port that has drivers for
Windows 7 x64 that I will use if I have to. I would prefer using the LVB
Tracker with its USB to serial adapter if someone has another solution.
Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to
get some telemetry packets. The satellite would remain on for less
than one minute after being commanded on. A quick test of the "bent
pipe" voice mode repeater was successful. . The "hardware watchdog
timer problem" is still evident; as expected, spacecraft temperatures
are insufficient to keep the transmitter ON (needs to be above 15 deg
Orbit projections suggest that satellite illumination conditions will
not result in increased temperatures for nearly 10 years. Command
stations do periodically turn AO-16 "ON" to check on its condition and
see if the hardware timer problem has "automagically" fixed itself
(which in not anticipated, but who knows...).

Here is another teaser :) Several months ago I commanded the AO-16
S-band transmitter ON; it too remains functional (albeit weak), and
was received by me, Drew KO4MA, and Alan WA4SCA.

I think I had a very small signal from Williams beacon frequency.
Pass with AOS here in Copenhagen 1422 UTC - but just 1 degree of elevation
in my worst direction.
Hope I am right.
Should be a good pass over NA in a few minutes.

I have both a commercial and a homebrew Eggbeater and am disappointed with both, especially in light of its rather high price. Connected to my IC-7000 via an ARR mast-mounted preamp, performance is far less than with an HT and an Arrow. Guess an omni can't cut it, at least not from my QTH.
Maybe if I could get it up higher, clear of all roofs, it would do better. I can make contacts at relatively high sat elevations, but can do just as well with a $10 dual band ground plane. My friend has an Eggbeater and the same preamp at a clearer QTH, and he hears substantially better, down to 10 degrees elevation in some directions.
Good luck and 73,

Dear HAMSAT VO-52 users,
The commands to 'Turn On' the transponder # 2 (Dutch transponder, made
by Williams PE1RAH) on-board HAMSAT VO-52 was successfully sent during
14:00 UT 35 deg ascending Node pass over Bangalore, India.
The sent commands were successfully received, acknowledged and
confirmed by the telemetry. Subsequently, the transponder # 2 is now
'ON' and Williams CW message beacon was heard again after a gap of
approximately 6 years & 4 months.
The beacon signal was heard loud and strong here at Bangalore.
A detailed Initial reports addressed to:
and a copy to
would be greatly appreciated.

I'm thinking of retiring my Endeavour rotor control interface for something newer.
Is anyone using a Fox-Delta ST-1 (USB) with MacDoppler on an iMac?
I know that MacDoppler and the ST-1 are supposed to support the EasyCom protocol,
but I'd like to know if anyone out there is actually using this combination.
Two attempts were required today. The first one was stopped at less
than T-1 minute and the countdown resumed after about an hour. The
test appears to have been successful.

Changes to the IARU Satellite Advisor Region 1
I have recommended to the IARU Satellite Adviser that Mike Rupprecht
takes over membership of the advisory panel form Norbert Nothoff and I'm
happy to notify interested parties that he has agreed to appoint Mike,
DK3WN as a panel member. He has thanked Norbert, DF5DP for his support
as a member of the Advisory panel for many years and said that he is
looking forward to work with Mike.
Mike Rupprecht, DK3WN will help with the IARU Satellite Frequency
Coordination process in Region 1 and in particular here in Germany. Mike
is very active and well known on the satellite bands and Internet
boards, and he has particularly profound knowledge of all cubesat
operations. He is also very well known in the community of cubesat
operators, including excellent communication connections to that groups.
Mike Ruprecht, DK3WN will support Norbert Nothoff, DF5DP and take over
the coordination process of satellite projects from him, which includes
correspondence with the coordination group and the satellite operators.
Norbert Nothoff, DF5DP will continue to stay in charge of anything which
is related to government issues (government and office liaison, laws,
bylaws, and regulations of satellite operations) in Germany.
