Dean, ZD8DC is currently active from Ascension Island on FO-29 and possibly
also AO-51 and SO-50.
So far he has been worked in South Africa on FO-29 by ZS1LS and ZS6WB. In
both cases the contact has been on a weekend morning ascending pass when he
was heard calling CQ around 435.843 MHz SSB.
His activity will probably be mostly on weekends as he works during the week
but he could have some good common windows on FO-29 into Africa, South
America and Western Europe.
If you are in these areas watch for him especially on 23-29-30 August. He
will complete his work assignment on Ascension and return to the U.S. on 02
If you have not watched (PS8RF) Piraja's video of the audio received from
ZS2ACP on AO-7 do not miss it. It is an excellent presentation and hopefully
will encourage others to work AO-7 DX:

According to Martha, in 2009 we have spent a grand total of $12,361 on
Suitsat-2. The 2008 files are not right at hand, but the expense was even
less. In comparison we've spent more on ITAR legal help trying to free our
volunteers to resume work on P3E.
The launch cost for Suitsat-2 will be zero for AMSAT. Nothing paid by AMSAT
to Russia, nothing paid by AMSAT to NASA. Nothing.
Launch cost for cubesats to LEO (600-800 km) is ~$70,000/kg. Suitsat-2 is
I'll let each individual decide whether they think that's a deal or not.
It's painfully obvious to me.

Two things to keep in mind. NASA (USA) is one

Second, the MIR space station was orginally intended
to have a 5 year life span. It ended up flying for 15 years.

One other important thing to remember about SO-50. Unlike AO-51 and AO-27, it does not transmit a carrier. You won't hear any noise unless someone is transmitting. You can't just wave your antenna around and peak for maximum on a carrier. So unless you are running full duplex and can hear your own signal, in times of low activity you don't know if you are getting into the bird.
Although SO-50 is not as strong as the other birds, you can work it easily with an HT and an Elk or Arrow handheld antenna.

Today in the orbit of number 59094 of AO-7 ( MODE B - 20:14:21 UTC - 21/08/2009). Could hear the Andre, ZS2ACP calling CQ and reporting signal to another station here in Brazil (PY5LF). Unfortunately I could not find the uplink, was prepared, but I missed the time to call it. Despite the weather have been enough I could not hear me. That's it friends, the AO-7 in spite of 35 years continues to bring surprises to the Community of users of satellite.
I Posted the video/audio in two links:

I think you need only 3 wires for one rotor, and 2 wires for the other (because you'd use the common hot from the first rotor). However, you wouldn't know meter reading for end of travel of the motor, and could damage the rotor.
If you are using the remote tracker interface (such as LVB that has front panel control as well as PC control), you could maybe run long cable from the tracker interface (in your shack) to the controller (in your garage), and you would have both control and digital readout of the position, and the LVB would know end of travel of each motor.
