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 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,

A Technician class friend of mine and I would like to ragchew between
His QTH in Lindale, TX (32.495164 N, 95.513233 W) and My QTH in
Phelan, CA (34.436400 N, 117.468649 W) with the exception of oscar 0
is anything flying that would enable this on a frequency above 50MHZ?
Doing what I try to do every vacation which is try to spend a little time
back on the birds. I've yet to have a QSO on HO-68. I hear the beacon just
fine. But I just finished my 2nd pass from NJ and was unable to hear any
signals let alone myself coming back on any mode. Did I misread the
operating schedule or am I doing something wrong? MacDoppler told me there
was a good pass to this part of the world are around 21:30 my time. Great
beacon strength but nobody else was home.
I was visiting FN95 on my vacation; beautiful hilltop with about nearly 360
degree visibility. I first caught a 30-degree elevation using my F6A with
stock rubber ducky. I had to twist it around a bit to find the right best
orientation (horizontal this time) but I got a nice signal the entire pass.
I hope I have recorded some SSTV that I can decode once I get back home.
That will be cool!
Next orbit (about 23:58Z Aug 29) it went directly overhead (or close). This
time I happened to hit the greeting in English, which was clearly audible,
although I did not get as much SSTV. I probably wasn't tweaking the doppler
enough or getting the orientation right.
Bonus: ISS came over 5 minutes later and I got to ooh and aaah our friends.
Now that I have a few things that work, I can eliminate some of my sources
of trouble at the home QTH, and hopefully get the signal back where I have
the decoding software etc set up!
Whoo-hoo! This is fun! And the telemetry sounds like the solar panels are
holding up well even if the battery did not!
Edition 58 of the IARU Region 1 VHF-UHF-UW Newsletter publishes the
notes from the key C5 committee meeting at the IARU-R1 Sun City
There are a number of Italian repeaters operating in the Amateur
Satellite Service segment from 145.8-146.0 MHz causing interference to
the uplinks and downlinks of Amateur Radio satellites. Among them are:
IR0MA 145.99375MHz -1.975 Roma, Lazio
IR7AZ 145.97500MHz -1.250 San Giovanni Rotondo , Puglia
Also these Italian repeaters using other modes:
FM: IR0CK 145.8500MHz -0.600 Roma (Internet Linked)
Echolink: IQ0FP 145.8875MHz Node 522 131
Packet: IK4MTK-6 145.975MHz Parma, North Italy
The IARU-R1 Sun City conference C5 committee meeting notes say:
SC11_C5_16 – D-Star in Italy using SAT-Band
IARU R1 stresses the importance of satellite service and band plans
also in case of the introduction of new modes. It is recommended to
disconnect repeaters/nodes from international D-Star network if these are operated in contradiction to IARU-R1 band plans.
1. Write the repeater operator to remove out of satellite segment.
2. Inform the trust server operator of the IARU bandplan breach made
by the use of the repeater.
3. Inform the government about the repeater and request them to remove
