Another one to consider and I haven't seen it already listed, is the LabJack U12 along with its Piggyback. The Piggyback schematic can be found at http://www.dk1tb.de/lj_piggyback.JPG. The instructions for using the LabJack U12 are found under ?Hints (Rotor) Readme(Labjack.txt). I think it cost me less than $20 in parts to build the Piggyback. The Piggyback interfaces the LabJack U12 to the rotor control box; the U12 then interfaces with the computer via USB. SatPC32 also shows the LabJack U3 but I am unfamiliar with the capabilities of it. LabJack U12 info can be found at https://labjack.com/products/u12The LabJack U3 info can be found at https://labjack.com/products/u3. The U3 Piggyback schematic can be found at http://www.dk1tb.de/lj_piggyback_u3.JPG I have 2 of these U12s and both are solid. My first Piggyback I bought with Nova a long time ago. I build the second one so that I made sure I had spares since I loan my equipment out for schools to have an ARISS contact. Hope this helps. 73,Charlie Sufana AJ9NOne of the ARISS mentors In a message dated 2019-03-07 07:39:46 Eastern Standard Time, johnbrier(a)gmail.com writes: Below is a list of interfaces.

Computer Control of Yaesu G-5500B Rotor
by Les Rayburn 07 Mar '19

07 Mar '19

With a lot of help from Marcus Thomas, KF4YHP I finally completed the installation of my Yaesu G-5500B Az-El rotor tonight. This will allow my 432, 2 Meter, and 1296 antennas inside my attic to finally track satellites throughout their passes. I’d like to have computer control of the rotor using SatPC32. Can anyone point me towards an assembled interface that will work well? Saw this on ebay, but not sure how well it will work with SatPC32. Any thoughts? https://www.ebay.com/itm/USB-Rotator-control-interface-board-box-for-YAESU-… <https://www.ebay.com/itm/USB-Rotator-control-interface-board-box-for-YAESU-…> 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

AO-92 L/V with an Alinco DJ-G7T full-duplex (long)
by Patrick STODDARD (WD9EWK/VA7EWK) 06 Mar '19

06 Mar '19

Hi! I have written a bit about the Alinco DJ-G7T and using it on satellites on this list over the years. I wrote about using it on AO-92 in both U/V and L/V modes last year: http://amsat.org/pipermail/amsat-bb/2018-February/066923.html Until the past weekend, I had always worked AO-92 L/V with two radios - transmitting on 1.2 GHz from the DJ-G7T, and receiving the 2m downlink with my Kenwood TH-D74 (which can also record the downlink). I have used a couple of different antennas, but have wondered if the DJ-G7T could work the L/V mode full-duplex like it can work U/V (with some caveats) full- duplex. Now, I have tried this for myself, and will ask the question... Can the Alinco DJ-G7T work AO-92's L/V mode full-duplex? Yes. Before the past week or so, I was aware of the triplexers offered by Diamond that included a 1.2 GHz port. Those are noticeably larger than the diplexers from Diamond and other manufacturers, and a larger price tag as well. I saw something online that mentioned the Diamond MX-37 diplexer, having one port for HF through 470 MHz, and the other port for 800-1300 MHz. Physically, the MX-37 diplexer is similarly sized with other diplexers, and it has two coax pigtails for those two ports - coax with an N connector for the 1.2 GHz port, and a PL-259 on the other pigtail for use with the lower frequencies. The common port is an N socket. After I received this diplexer in the mail, I was ready to fit it into my portable AO-92 L/V station. I have been using a 10-element 1.2 GHz Yagi for AO-92 L/V in the past few weeks, and I tie that to the PVC handle of my Elk log periodic. I decided to tie the MX-37 diplexer to the PVC handle behind the antennas. This allowed me to connect the 1.2 GHz side of the diplexer directly to the coax pigtail from the Yagi's driven element. I used a 3-foot/1m length of coax from the PL-259 connector on the other side of the diplexer to the Elk's coax feedpoint. From the common port on the diplexer, I ran another 3-foot/1m length of coax to the DJ-G7T. To keep from causing audio feedback while transmitting, an earpiece or something like that needs to be plugged into the DJ-G7T. The DJ-G7T uses a single 4-conductor 3.5mm jack for speaker/mics. To split out the speaker jack so I can use an earpiece and an audio recorder, an adapter is needed. I use Alinco's EDS-10 adapter, which provides a 3.5mm speaker jack and a 2.5mm microphone jack (don't need anything in the smaller jack for this). Alinco also has an EDS-14 adapter, which looks very similar to Yaesu's CT-91 adapter used with a few HTs (VX-6R and VX-7R, among others) - where the two jacks are on short pigtails from the 3.5mm plug. The Yaesu CT-91 adapter works fine with the DJ-G7T. The DJ-G7T only allows transmitting from VFO A, the upper VFO on the HT's display. I put the 1267 MHz uplink frequency in this VFO, along with encoding the 67.0 Hz CTCSS tone. I use 5 kHz tuning steps on this radio for 1.2 GHz. I set the volume for this VFO to 0, and tightened the squelch to the maximum. For the lower VFO (B), I put 145.880 MHz with the squelch left wide open, and adjusted the volume to a reasonable level using my earpiece. I used this setup for 3 passes over the weekend. The antennas were a little heavier with the diplexer on the handle, but I could still control them with one hand. I held the DJ-G7T, along with the splitter and patch cable to my audio recorder. I could still adjust the knob for the transmit VFO, and made some contacts on those 3 passes. It was fun to be able to use just one HT for AO-92 L/V. There are some tradeoffs when going from a two-HT setup for AO-92 L/V to just the DJ-G7T. The 2m receiver isn't as good as with other HTs, certainly not as good as the TH-D74 I have normally used when working L/V. I heard some other signals mixing with the AO-92 downlink on parts of a couple of passes. Of course, the DJ-G7T does not come with a built-in recorder like the TH-D74. There may have been a little less power going to the 1.2 GHz Yagi, passing through the coax to the diplexer's common port and then out from the diplexer to the Yagi, but I still got through. During one of the L/V passes, I was still able to get through AO-92 transmitting at low power from the DJ-G7T (rated at 300mW for 1.2 GHz). I posted some pictures of this setup on the QRZ satellite forum, in a long- running thread "Where's AO-92???", starting at: https://forums.qrz.com/index.php?threads/wheres-ao -92.614536/page-34#post-4986044 Audio from my recorder on the 3 passes I worked last weekend with this setup is in the "Satellite_Audio-2019" folder in my Dropbox space: http://dropbox.wd9ewk.net/ The direct link for the pass I worked Saturday evening, where the recording started at 0537 UTC Sunday (3 March), is: https://www.dropbox .com/sh/v3byggtuqw33fkk/AAA_gyTts4RpjT3jZa8GJI5ha/Satellite_Audio-2019/20190303-0537UTC-AO92-DM43bl.mp3? dl=0 Audio from the 1709 UTC pass Sunday morning is at: https://www.dropbox.com/sh/v3byggtuqw33fkk/AACeV6R0Bjh-RRPXTrNpblAca /Satellite_Audio-2019/20190303-1709UTC-AO92-DM43bl.mp3?dl=0 and the late-morning pass at 1843 UTC Sunday: https://www.dropbox.com/sh/v3byggtuqw33fkk/AADmbAfFYtHARDfULAR _J5eSa/Satellite_Audio-2019/20190303-1843UTC-AO92-DM43bl.mp3?dl=0 It is nice to see that the DJ-G7T is capable of L/V full-duplex operation, just as it is capable of U/V full-duplex operation, in line with Alinco's advertising for the radio - with some caveats. I can now alternate between a one-radio setup and a two-radio setup for AO-92 L/V. More fun with radios... :-) 73!
