JE9PEL/1 Satellite Listing
by Chuck 31 May '16

31 May '16

Greetings AMSAT-BB, Reviewing JE9PEL/1 satellite listing (http://www.ne.jp/asahi/hamradio/je9pel/satslist.htm) there are a good number of satellites listed as FM such as AO-85 and others. Being somewhat new to AMSAT I have to ask are all FM satellites noted on JE9PEL/1 list available to amateur radio operators unless noted otherwise? Or are just the communications FM satellites listed on AMSAT Communications Satellites web page the only available FM satellites for amateur radio operators use? Thanks & Cheers Beers Chuck AI6OZ

Hi Rico, I'm fiddling with it and when the setup works I will publish it. Frequency purity (phase noise etc) and stability is of paramount importance. A famous Dutch saying states: "Don't sell the skin before you shot the bear." ;-) I made a picture of my UMTS pallets, see: http://remco.org/umts.jpg These are (unfortunately) 26 - 28V modules, obtained from a flea market for . . . 10 Euro each. Remco PA3FYM >Hi Remco, > >Sounds like you made a lot of progress on your Es'HailSat2 groundstation >already. I would be interested to learn more about your transverter design >and where you got the UMTS PA, and I'm sure some other people on this list >too. :) > >Rico PA3RVG

EsHail Microwave transponder satellite

>What are other folks planning to use on the uplink 2400 MHz and the down >link at 10,489 MHz, for the narrowband linear transponder ? I will use a cheap injection locked X-band PLL LNB with dielectric rod and additional converter to let the NB transponder land inside one of the bands my transceivers accomodate. For the S-band uplink a dedicated (simple!) TX converter is now prototyped. Output of the converter will be around 5 dBm to be inserted in an old UMTS (2.1 GHz) module, capable of delivering around 20 - 30W at 2400 MHz on the bench with this drive. Of course uplink output can be tweaked. I am also busy with the dual band feed, of which the downlink of course is inside the LNB. For the uplink I made a 6 turn LHCP helix but am now fiddling with the matching due to mechanical boundary conditions. At this moment of writing I (still) haven't a good match but I reckon this mechanical issue will be solved soon. Secondly I need to experiment with the phase centers of both up- and downlink to maximise overall efficiency. Even when I'm not able to equalise both phase centers I have some room in my uplink budget to compensate for suboptimal illumination. In my prototype the LNB looks 'through' the helix. Antenna will be a Triax 88cm broadcast satellite dish with f/D of around 0.6. All internal frequencies will be/are locked to GPS which allows my idea of building a SUT (satellite user terminal) [for portable use] in conjunction with one (1) transceiver. In other words, my concept will be that Es'hail2 behaves like a normal amateur band, albeit with some delay ;-) Remco PA3FYM

Polarization
by Ken Alexander 30 May '16

30 May '16

I clipped this from another message because I didn't want to drag the discussion off course. It's a question I've been wondering about since getting into this a few short weeks ago. I've also read (but haven't tried yet) about the trick of rotating the antenna 90 degrees on transmit, once you've established the best receive orientation. 73 de Bill, KG5FQX So far, with SO-20 I have rotated my Arrow antenna for best reception of the downlink and don't think I've had too much trouble being heard. At the same time I have wondered whether I should twist the antenna when transmitting to orient the 2m elements to give the same polarization as in receive. I don't know if this is a good idea or not, and frankly I have enough trouble remembering calls and grids, tracking the satellite, adjusting frequency and switching back to the correct VFO to worry about one more thing. I've seen that some commercial OSCAR antennas use circular polarization. The antennas I see in the photos of satellites we work are whips. Is the polarization becoming "circularized" as it re-enters earth's atmosphere or something? Comments and observations would be most welcome! 73, Ken Alexander VE3HLS, FN03
