Hi Mike, Here are two more to consider. One is the LVB Tracker box, but that one seems to be hard to find if you want one that is already built. The other is the LabJack U12 (https://labjack.com/products/u12) or U3 (https://labjack.com/products/u3).%C2%A0 I think many folks do not realize that these have been around a long time and are pretty foolproof. For the LabJacks, you will need to build up an interface card (cost is probably under $20) to go between the LabJack and the rotor control box. SatPC32 has schematics for both (http://www.dk1tb.de/lj_piggyback.JPG http://www.dk1tb.de/lj_piggyback_u3.JPG).%C2%A0 The U12 (I have two U12s, but I don't have the U3) and the LVB both work great with my G5400B and SatPC32 or with Nova. I have loaned out my spare U12/piggyback to the ARISS schools that I mentor if they don't have something; they haven't broken it yet. Good luck. 73, Charlie Sufana AJ9NOne of the ARISS mentors In a message dated 2019-09-06 18:30:14 Eastern Standard Time, amsat-bb@amsat.org writes:
What are folks using now to control a G5400B rotor system with SatPC32? I have my trusty SatTracker 688 from WA8SME, but that is no longer available.
