Fw: AO73 Mode change
by Graham Shirville 10 Jun '19

10 Jun '19

Hi folks, AO73/FUNcube is now in amateur mode for the weekend with the transponder on! Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Using 1.2Ghz
by Todd 04 Apr '18

04 Apr '18

Thinking about adding the 1.2Ghz module for my 9100. Prices have dropped a little and units will start become harder to find once production ends. Anybody using this band? I read it's used as a uplink frequency for some satellites. Any input appreciated.ToddAL7PX

Outernet L-Band now carries AMSAT and ARISS weekly bulletins
by Robert Bruninga 17 Mar '18

17 Mar '18

The Outernet L-band feed is now carrying a condensed version of the AMSAT and ARISS weekly news files. (Global Geosat coverage except for Northern Alaska)... Receivers are simple: http://aprs.org/outnet.html For ARISS, I manually added a 2 char grid square to each school listed in the school schedule and am asking the outernet folks to parse out that location info and plot a 1200 km footprint on their weather globe showing where people can tune in the ARISS contacts. Then their RTL-SDR dongle could then actually be retuned to hear the contact. Just an idea...

Re: [amsat-bb] Cleaning up the Global APRS Satellite ground station network (update a)
by Roy Dean 31 Aug '17

31 Aug '17

Bob - I have a cheesy omni running direwolf that had been running a 5 second delay. I changed it to the new symbol (from the black diamond with "R" overlay), and also changed it to the "O" overlay as the "SATGATE" delay has been changed to 15s. Do I understand you correctly that I should leave the overlay on because the 15s delay is implemented? Or by "blackhole fix", do you mean an IS system wide fix? --Roy K3RLD So you can use \] now, but do not use any of the overlays until the > blackhole fix is implemented. > Maybe later the FINDU search can include a wild card for the overlay so we > can search for *] symbols. > > Bob > >

Re: [amsat-bb] Cleaning up the Global APRS Satellite ground station network (update a)
by Robert Bruninga 31 Aug '17

31 Aug '17

[Updated in response to feedback from the initial post on 7 Aug] We need to better organize our APRS satellite ground stations network. Over an 18 month review, we found about 330 unique IGATES feeding the APRS-IS and captured by the two APRS live satellite web pages on FINDU: http://pcsat.findu.com and http://ariss.net A hot topic at SmallSat conferences is always the need for remote ground station networks. But for two decades, APRS has always had a global ground station network with hundreds of SATGATES on the APRS downlinks of 145.825. Here are some problems that I think we can solve: 1) The black-hole problem of locals direct to Satgates not showing up on the downlink pages 2) No means for premium stations to self identity 3) No means to easily compare satgate capabilities 4) No means to easily indicate satellite traffic captured on other frequencies 5) No easy means to visualize the network in real time 6) The problem of distinguishing RX only SATGATES 7) Future potential for remote transmission via a remote SATGATE for satellite controllers BlackHole Fix: Steve Dimse, K4HG, the author of FINDU proposes: Proper SATGATEs clients should simply delay any directly heard packet for 15 seconds when operating in satgate mode. If a local station successfully digipeats via the satellite and is captured either through this satgate or through another satgate, then the digipeated packet will make it to ariss.net before the directly heard packet. Putting this into all SATGATE software clients would solve the problem (in the area of that satgate and in the area of that user). There are far too many different APRS IGATE clients to make this work across the board. But when combined with our goal to more formally define and identify the APRS-Satellite Ground station network, it does become a viable approach when we use a unique symbol just for these new SATGATES. As previously proposed, we define a new SATGATE symbol, \] that is currently unassigned for SATGATE stations that are permanent parts of this network. Then, when they implement the 15 second delay on direct-heard packets to solve the black-hole problem, they can further segregate their major capabilities using Overlay characters. Phase 1 begins with identifying all permanent SATGATES intending to participate with the special \] symbol. Phase 2 adds blackhole fix to clients which then self-identify their class overlays on that symbol. \] For immediate use by permanent satgates intending to self-identify as part of this network (but w/o the BH fix) A] for AMSAT Oscar class tracking station (2-way, 50W typical radio) L] for Lower gain class stations (think, Arrow antenna, 3 elements on VHF) O] for Omni antenna coverage (no tracking) H] for HFSAT (that will be our next one in a few years) U] for UHF downlinks ( channel TBD) S] for Schools and University class A stations R] for future class A remote access satgates (for satellite operators only) V] for Class A stations scanning and tracking Various other satellite downlinks APRS traffic T] for omni stations that similary Tune other satellite downlinks APRS traffic P] for Portable stations currently operating in non permanent locations FINDU shows no current users of this symbol. But once SATGATE stations begin to implement it you can see them using the FINDU filter: http://www.findu.com/cgi-bin/symbol.cgi?icon=\]&limit=200 So you can use \] now, but do not use any of the overlays until the blackhole fix is implemented. Maybe later the FINDU search can include a wild card for the overlay so we can search for *] symbols. Bob

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

AO-85: Tone or no Tone for SSTV
by Roy Dean 30 Aug '17

30 Aug '17

two questions: According to Amsat website, 67Hz tone is required for a couple of seconds to activate repeater. Once the repeater is activated, does it still require the tone every couple of minutes to stay on, or does it only start the timer after normal ("un-toned") activity stops? Will constantly sending the tone during SSTV Tx mess with the SSTV Rx? I'm planning on eventually trying my own image, and want to be sure I don't waste 36 seconds of valuable airtime. -Roy K3RLD

ISS Crossband Repeater
by Gabriel Zeifman 28 Aug '17

28 Aug '17

Hello fellow bird folk, I noticed in the ANS today the specific note that the recent crossband repeater activation was not to be used for general amateur communications. With the popularity of this mode (and our current shortage of FM birds), has there been any thought about making it a more common thing? It seems to be wildly popular when it is active, and I'd like to think people would have more respect for the times when it needs to be used for scientific functions if it wasn't seen as just a really rare opportunity to make a QSO via the repeater. Maybe there's a reason it's basically always off, just curious. 73, Gabe NJ7H/VE6NJH

Eclipse Day APRS balloons?
by Robert Bruninga 28 Aug '17

28 Aug '17

I added the PLOT of all the 46 APRS balloons on Eclipse day to my Balloon page. http://aprs.org/balloons.html I assume these were trackers on all the 50 NASA balloons launched that day by students all across the country to stream live video of the event. But there is not a single mention of APRS on their web page, and not a single Ham has mentioned involvement here on the APRSSIG or on AMSAT. Yet all the balloons had Ham calls. I’d like someone involved to document the HAM involvement in this massive undertaking and describe the APRS portion so I can add it to the web page. And why does FINDU.COM find about 148 Balloons in the USA, and I can only count about 50 along the path and only a few more..? Bob

Labour Day Rove
by Ken Alexander 26 Aug '17

26 Aug '17

The nurse has given me limited clearance to go away on Labour Day Weekend, so I will be making up my failed previous attempt to activate FN27/28. Friday and Monday will be travel days, and I'll spend Saturday and Sunday on site. If the roads are no worse than I have encountered on previous roves then I will attempt to activate FN37 as well. I also plan to stop briefly for a few passes in FN26 on the way north on Saturday morning around 1400 to 1500. Hopefully, not too early for western and west coast operators. I will spend Friday night in FN25 and Sunday night in FN24 on the way home. I'll be on in the evenings from those grids. My limited research shows that nobody has FN27/28/37. It ought to be a busy weekend! Let's hope for good weather! I'll post schedules as we get closer to departure day. 73, Ken VE3HLS

Kenwood TS2000 satellite rig for sale
by John Geiger 26 Aug '17

26 Aug '17

I have for sale a Kenwood TS2000 HF/6m/2m/70cm satellite rig. This is the model that does full duplex for the satellites, and does 100 watts on HF, 6m, and 2m, and 50 watts on 70cm. It has IF-DSP so you don't need any optional filters and you also get noise reduction and an auto notch filter. Has a built in TCXO, CW memory keyer, subreceiver that does AM/FM on 2m and 70cm, and can also be used for Crossband repeat or Skycommand. Also has a built in autotuner. This is a 800xxxx serial number so it was produced before the bad filter issue occurred with the TS2000. It comes with both original boxes, the original manual, hand mic and power cord. It is in very good condition with just a couple of very light scratches on the case. I am asking $900 shipped in the US, and can take paypal/check/mo. 73 John AF5CC

Re: [amsat-bb] FW: Solar Panel delivery to Maryland
by Robert Bruninga 26 Aug '17

26 Aug '17

> Where did you purchase them in Miami? It is SUNELEC.COM They have unbelievable deals. They also ship from Arizona I think... They have tens of thousands of panels for prices typically between 30 to 50 cents a watt. Solar power for the home is now way under the cost from the utilities, but only if you are grid tied. If you try to store the energy in batteries every day, your costs for the system will triple and you will have battery maintenance issues for life. Plus not enough power in the winter, and too much in the summer. See http://aprs.org/solar-now.html So it is so cheap, but here are many considerations.... * Solar energy now costs much less than the utilities if grid-tied. * But only in states where the utilities are not sleeping with the politicians * You cannot grid-tie unless you have a licensed electrician do it and get all the permits. You will pay around $3/watt installed. * Hint for DIY types: Contract for a very small system. Then add your own panels later (while fully following NEC code). * Going off grid makes no economic sense whatsoever if you have the grid. You will pay three times more for the batteries and never recoup the investment as you always have to maintain and replace batteries for the rest of your life!. * Solar panels are excellent for remote sites where you have no grid and having battery solar power is worth paying triple what it is worth. * Solar panels are great for RV's, Boats or Electric cars... ANYTHING that already has to have a battery anyway, may as well charge for free. ** A small solar panel on the house for the shack makes no economic sense whatsoever. You have the grid, so just charge the shack backup battery from the grid. Don't bother with solar. Also, every single day the grid is UP, you are not using the backup battery so your solar is producing absolutely nothing anyway 99.96% of the time (In Maryland anyway, that is the grid reliability).. ** But if you plug that solar panel into a small 500W Grid-Tie inverter that just plugs into a home outlet (cost under $100 on ebay) then you DO get full retail value from the solar everyday for ever AND you can use the panel direct when the grid goes down. butt don't get greedy... ** But ONLY if you never backfeed more than you are using every minute of the day. If you ever backfeed more than you use, you will pay double for it. ALl non-NET-meters charge for electricity going through the meter no matter which way it goes! So you pay when you over produce and you pay again when you draw it back out later. That is why you MUST have a NET meter to have any hope of economical solar in bulk. ** Thus, a plugin grid tie more than one or two panels will end up COSTING you for every watt you over produce. So, again, the only economical solar is whole house legal net-metered grid tie. And it is so cheap it makes no sense not to do it that way. But if you still want to have a single panel for $100 its great to have 30 volts at 7 amps from the sun, even if you just waste it. But then having to pay $100 for shipping for a $100 panel doesn't make a lot of sense either... Your mileage may vary.
