Thanks, Ben. Good info! So you think Yaesu changed the pinout between the
AC and the DC versions? Annoying!
I know that a number of people have used the ST2 without issues. And that
is pretty much a clone of the LVB Tracker, which I use with no problem.

Yaesu may very well have changed the pinouts between the versions.
Another slightly annoying thing is that there?s no mention of what the
voltage adjust does (if anything!) in the manual. I tried taking some
measurements to see if adjusting it made any changes to things during
this whole process and it doesn?t appear that it?s used at all. No
difference in DC voltage supplied to rotors on controller pins 4 & 5 and
no difference in voltage supplied to the DIN pinouts.

I also noticed a lot of fading. I heard you and KB2M but not very clearly.
I made a QSO with KI5DVX near the end of the pass, but it was rough going.
Maybe the satellite antenna was just in a bad orientation this morning.

I'm going to get set up to monitor Fox telemetry. For those of you who
already do so, what antenna are you using?
I'm set up with 2M, 70cm, and 23cm CP antennas on a G5500 rotator but I
understand I can also use a fixed antenna such as a Lindenblad or
quadrifilar. Suggestions?

I've been using a 3/4 wavelength ground plane (vertical with 4 equal length
radials) in my attic for the last couple of years, and have usually been in
the top 60 on the leaderboard for the fox satellites. Lately I've been
having FoxTelem stability issues, though (pretty regularly getting a usb
access error).

Roy,
In my experience, using the CP antennas with the G5500 will help you collect
and decode about 4-6 times more packets than an omnidirectional antenna.
But tracking the Fox satellites using the Yaesu rotors will wear out the
rotors in 4-8 months. Replacement rotors are about $250 each (you won?t need
to replace the controller).
YMMV

I have two systems, one with a Lindenblad (AA2TX design, homemade) and the
other with a dual-band J-pole. Both work pretty well, but not as well as a
beam on a rotator.

I don't want to wear out my G5500 so I'm looking for the best alternative
antenna(s) to collect telemetry data.
How about a dual-band Arrow antenna pointed straight up? Surely that's
better than the J-pole but not as good as the CP Lindenblad.

Sounds like we need an electrically-steerable phased array for 2 meters. :-)
At 70cm, it might be practical.

Kevin,
I'm in West Lafayette, Indiana, so no salt water. My antennas are M-squared
medium size antennas, 2MCP14 and 436CP30 with polarity switches, so not
overloaded.
Mark N8MH, has had similar experience with his Yaesu's. Since he is a
dedicated telemetry collector like you, and since he is a control operator
for the Fox satellites, he replaces his rotors when they fail. He had a
volunteer to repair his broken rotors, so I transported 6-8 rotors from his
garage in North Carolina (not near salt water either) to Indiana. Half were
elevation rotors, half were azimuth rotors. I thought I was just having bad
luck until Mark shared his experience.
The last time mine failed, it was the azimuth rotor. Pointing the Yagis
south just above the horizon worked a little better (long term) than an
omnidirectional antenna. Since it failed while I was on a 3 month trip, I
couldn't replace the rotor.
I still recommend the G5500 rotors for normal operators, but they may not be
the best choice for 24x7x365 telemetry collection. (I'm glad they work for
you in that mode.) I've since switched to an AlphaSpid rotor with a Green
Heron controller. You can buy the AlphaSpid rotors without the controller
(my recommendation for heavy duty use) and use a Green Heron instead.
Still: YMMV
