Need for 2M antenna preamp with Icom 9700?, Receive tip for what it's worth
by Wes Baden 13 Jan '20

13 Jan '20

(1) Preamp question: AMSAT newbie here, just having made my first contacts with an Icom 9700 and small yagis on tripods on my deck, fixed in place due to Maine weather. Come Spring, I plan to install the M2 LEO Package on an existing tower, with a rotor. I'm interested primarily in Mode B, and so here is my question. Do I really need a mast-mounted preamp with this set up? I'll be using a 100 foot run of LMR 400, by the way. Right now, with a 2M 4 element yagi and a 30 foot run of LMR 400, I have no trouble copying a lot of signals on receive when satellites are in the one yagi's beamwidth, given the 9700's extraordinary sensitivity and built in preamp. Would a 2M mast mounted preamp be overkill and an unneeded expense? (2) Receive tip: For what it's worth (and probably old news to most SAT ops, so I apologize in advance)…. When using CW on the 70 cm uplink, I've kept the 9700 on USB while listening on 2M. The SSB filter is almost 2 KHz wider than the CW filter. This has enabled me to listen to Doppler shifted CW signals with little or no RX tuning, hear any adjacent QRM and avoid it, and just have one button to hit when I switch from CW to SSB, transmitting on 70 cm. Thanks in advance for feedback about the need for a 2M mast mounted preamp. Wes NA1ME, FN54

IC-9700 ?
by James Brown 12 Jan '20

12 Jan '20

I now have sat32/scope working nicely. last week before I added the cat v cable and upgraded to the scope version, I had set up wstj to the ic 9700. I had not actually used it or decoded any signals. It occurred to me that WSJT is controlled only thru usb. I dont see any option to run cat to the wsjt and get audio to it just like sat32 scope? I hope some one has accomplished this. I am hoping to try at least to hear /decode something from Reno on WSJT, but I expect it will be a tall order. Thanks Jim KI6WJ

LNA or reduce noise first?
by Chris Prosser 12 Jan '20

12 Jan '20

Hi Folks, I would love your opinion on my next steps. I've been slowly putting together a station. I finally got it operational and I'm having a really hard time hearing anything other than morse code off satellites (mainly the XW birds). I can pick up some voices from the linear transponder, but it's too buried in noise for me to make out. Key Facts: * For an antenna I'm using a yagi I built from "Cheap Antennas for the AMSAT LEO's Kent Britain -- WA5VJB" * fixed elevation of 15% on a rotator. * 50 feet of LMR-400 (in 30/10/10 segments) running from my shack on the first floor up to the 3rd floor balcony where the antenna is. * UHF Connectors * SDRPlay RSPdx for receive. * no common mode chokes on either end of the transmission line * Live in north seattle, so bunch of noise already * ton of computer equipment in my shack with more switching power supplies than I can count. * LED lights, though I think I already sleuthed out the really bad ones. So...what are people's thoughts? Would an LNA help drown out the noise in my house and compensate for cable loss? Or should I start by doing the lengthy process of finding and ameliorating as many noise sources as I can first? Thanks, Chris -- Chris Prosser chris(a)nart.org

JSON API for Satellite Prediction?
by Bob 12 Jan '20

12 Jan '20

I think Heimir's (W1ANT) work on the JSON Satellite Status API is fantastic! Nothing like rewarding hard work with another request... How about a JSON Next Orbit API? Query would include the satellite name and a grid location. Response would be the time of the next pass information (AOS/Time/Az, Max El/Time/Az, LOS/Time/Az). That would make a small IoT gizmo pretty darned simple to implement and remind us when satellites will be overhead 73, Bob, WB4SON

The satellite was to have been put into service within 3 days. “If the V/UHF antennas are deployed now, additional torque may affect determination of the satellite attitude,” Kung said. “Engineers need to modify and upload the software, which will take some time.” He said that taking into consideration the upcoming long Chinese New Year holiday, the test work is planned to be completed sometime in late February or early March. At that time, VHF/UHF antennas will be deployed, and the amateur radio payload will be available for use. Kung points out that the satellite’s CW beacon has been turned on, although the antenna has not yet been deployed. “If you have a ‘big ear,’ you may be able to receive weak signal leaked from an undeploy- ed antenna on 145.910 MHz,” he said. “A polyimide cover on the anten- na chassis can help to leak some RF signal.” CAS-6 launched successfully on December 20, piggybacked on a TIANQIN-1 technology test satellite. The microsatellite will be known as CAS-6/TIANQIN-1, and the call sign is BJ1SO. The primary launch pay- load was the China-Brazil Earth Resources Satellite, CBERS-4A. CAS-6 is in a sun-synchronous orbit with an apogee of 390 miles. It carries a U/V linear transponder, with a downlink of 145.925, 20 kHz passband (inverted) and an uplink of 435.28 MHz. The CW telemetry beacon is on 145.910 MHz, while 4k9 baud GMSK telemetry will be trans- mitted on 145.890 MHz. [ANS thanks CAMSAT and the ARRL for the above information] --------------------------------------------------------------------- Telemetry Dashboard Available for SMOG-P and ATL PocketQubes The SMOG-P and ATL PocketQube team at the Budapest University of Tech- nology and Economics has released additional information about their satellites recently launched by RocketLab from New Zealand. SMOG-P digital downlink: 437.150 MHz ATL digital downlink: 437.175 MHz More information on both satellites is posted at: http://gnd.bme.hu SMOG-P (MO-105) is a 1p PocketQube (5x5x5 cm, 250 grams), a fully re- dundant tiny satellite with an actual scientific payload: a flying spectrum analyzer. It measures the scattered RF energy over the UHF band (specifically, in the digital terrestrial TV band) that can be detected in space. ATL-1 (MO-106) is a larger 2p PocketQube featuring the same spectrum analyzer experiment. Both satellites transmit almost identical telemetry data. In addition to basic CW telemetry carrying callsign, battery voltage and tempera- ture, there is digital telemetry with variable data rate and coding scheme. Most frequently, modulation is 1250 or 5000 bps GMSK. The data is encoded either by the well-known "AO-40" FEC, or a shorter, pro- prietary variant of it, but they can also use a more powerful, state- of-art repeat-accumulate (RA) coding scheme. Some practical information about receiving the telemetry: A GUI telemetry receiver is available for Windows and Linux (soon for OS X as well), and a command line receiver can also be used (Linux only). Both can be downloaded from: https://gnd.bme.hu:8080/index The programs are able to submit the received packets to the central telemetry data base. This requires a quick registration, the login credentials can be used with either of the decoders. There are some issues with the GUI software that hopefully will be resolved within a few days. These decoders assume either a USB receiver connected through the sound card or an rtl-sdr receiver. Thanks to Daniel Estevez, EA4GPZ, a high quality, full decoder and packet uploader is also available for GNU Radio 3.8 within the out- of-tree module gr-satellites. For uploading to the received packets, it uses the same login as the "official" programs do: https://github.com/daniestevez/gr-satellites/tree/maint-3.8 This decoder can unleash the full potential of the RA FEC. You'll need to put an FM demodulator in front of the flowgraph. The team is looking forward to seeing many submissions on the "Leader- board" from around the world: https://gnd.bme.hu:8080/leaderboard Having many receiving stations around the globe could greatly improve the global picture the spectrum analyzer payload can offer.

API for satellite status now being tested.
by Joseph B. Fitzgerald 12 Jan '20

12 Jan '20

Thanks to the efforts of Heimir, W1ANT, an API has been added to retrieve satellite status data as used in the amsat.org/status page. Send a query like : amsat.org/status/api/v1/sat_info.php?name=AO-91&hours=24 and you will get the last 24 hours of reports for AO-91 in JSON format. The hours parameter is optional, if you omit it you will get the last 96 hours of reports. The name of the satellite must match the string shown on amsat.org/status , i.e AO-91 works, but AO-92 does not ... use AO-92_L/v or AO-92_U/v instead. This API is not stable yet ... we are still working on the time, and it seems a query for the list of available satellites is in order. For the moment, all reports show half past the hour that they were in. de KM1P Joe

Android app now using the new Status API
by Heimir Thor Sverrisson 11 Jan '20

11 Jan '20

Hi all, Last year I wrote an app to help me operate LEO satellites and in December I decided to make it available in the Google Play Store. The app has information on the satellites I've found interesting, including the radio transponders and beacons on board, in addition to the Keps, that I fetch automatically on occasion over the Internet. In order to plan activity, the app will show a list of passes coming up for your QTH in the next 18 hours. Once you select a bird you are interested in you will get an Overview Page for it. From there you can select a link taking you to a web page about it, you can also see its Location in real time and its trajectory for the next hour. All passes for this satellite for the next 48 hours are also available from the Overview Page. >From the overview page you can also select Status Reports, that will display a list based on the Status API that I helped Joe KM1P to set up earlier this week. Finally if you select a Beacon or Transponder from the overview page you will land on the Aiming View that uses the built in sensors of the phone to point at where in the sky the satellite is in real-time. This view also shows the Uplink and Downlink frequencies with the Doppler shift included. I use this view with my phone mounted on a tripod behind the reflectors on my Arrow beam in portable operations. I would really appreciate any and all feedback on the app and thanks for making this hobby even more interesting. Heimir W1ANT P.S. The app called 'W1ANT Satellite Tracker' is available for free here: https://play.google.com/store/apps/details?id=com.coolprimes.sattrack

9700 scope
by James Brown 11 Jan '20

11 Jan '20

I want to thank all for the presentation and setup procedure for the ic9700 scope...Well Done!! being computer illiterate it was perfect for me. I tried to download today's revision of sat 32 and was blocked with a red slash thru the dk1... site. I have never experienced this before and will assume something at the site. My scope is all "red" changing the reference level and filter does not change the colors.Any suggestions.I will try another day to update sat 32 to todays revision. ThanksJim KI6WJ
