FUNcube Eval in DC-Balto Area
by Pat Kilroy 27 Apr '11

27 Apr '11

Yesterday I ordered a FUNcube Dongle Pro from Howard Long, G6LVB, and AMSAT-UK at http://www.funcubedongle.com/ for under USD$200 to evaluate. The next sale offering is expected on May 3. I am evaluating this SDR receiver for dual use on the Amateur Satellites and my STEM project of SimSat, specifically, currently, on quality of reception of my high-altitude balloon experiment PICetSat flight modules. We will fly again this summer. Part of the FUNcube Dongle Pro technical FAQ is reproduced below, FYI. I am looking for others who wish to also evaluate the same receiver for whatever one's purpose. Please let me know if you got one or when you get one, and what software you are trying. Thoughts? THANKS and 73, Pat Kilroy, N8PK AMSAT Area Coordinator MDC Area Technical FAQQ. What is the frequency range? A. 64-1,700MHz, although straw poll tests on pre-production units indicate that units can be stretched down to 51.5MHz or so. Upper frequency limit is beyond 2,000MHz. In testing, we have determined that there is a gap between about 1,100MHz and 1,270MHz where the design of the local oscillator VCO, PLL and divider chain in the tuner chip don’t provide seemless coverage. Q. What can the FUNcube Dongle receive? A. The FUNcube Dongle has no restriction on modulation schemes: it is limited only by the application program running on the host computer. As long as the signal fits within about an 80kHz bandwidth, the FUNcube Dongle is capable of receiving the radio signal. So, for analogue reception, as well as narrow band FM and SSB, it is also possible to receive, for example, sound subcarriers for TV broadcast. Similarly for data reception, as long as a data demodulator has been written that will accept standard soundcard quadrature I/Q reception, that will work too. Q. What is the bandwidth? A. 96kHz is the quadrature sampling rate. Once the ADC’s decimation filter skirts have been taken into account, you have about 80kHz. Q. What applications work with the FUNcube Dongle? A. As well as the forthcoming FUNcube front end application, any application that understands a standard stereo soundcard configured for quadrature, or I/Q, reception should work. Examples include Linrad, Spectravue, Rocky and M0KGK. Q. What is the sensitivity? A. Each unit is tested for 0.15uV for 12dB SINAD NBFM at 145MHz and 435MHz. Q. What operating systems are compatible? A. Currently Windows 2000 SP4, XP 32 bit, and Vista and Windows 7 32 and 64 bit have been tested. The sound card element works with Mac OSX and Ubuntu 10.10 32 and 64 bit, but the frequency setting application has not been ported yet. [snip] Patrick L.

Listening for AO-27 among Other Sats
by Kilroy, Patrick L. (GSFC-5680) 25 Apr '11

25 Apr '11

Hi Bruce, Thank you for your fine information; it was very helpful over the weekend. Only problem, at least as far as AO-27 goes, its schedule was not good for us in the Greater DC area. And won't be for a while. Regardless, I listened once or twice for this particular sat over the weekend and heard nothing. Such was my luck. ;-) Comparing the AO-27 schedule from http://www.ao27.org/AO27 and http://www.amsat.org/amsat-new/tools/predict/ . . .

So - if appears not to be on -- be patient -- it will come on during some part of the pass. Bruce WA3SWJ

Re: HOPE-1 aka HO-68 and others

Hey, Ben, According to the status page Bruce Semple shared with us, http://oscar.dcarr.org/index.php it says the TLM-only downlinks have been heard at least for the past few days. Also, it looks like AO-27 has been OFF when passing over DC today (and longer?) per http://www.ao27.org/ and confirmed by my ears. We'll keep trying. FYI, the recent posts have created nice "what did you hear" conversations on the Goddard Amateur Radio Club repeater, WA3NAN/R, in Greenbelt, MD, on 146.835 MHz FM. Hope to hear more folks on it over the weekend and early next week.

FM Repeater In the Sky - FYI - Recordings
by Bruce Semple 21 Apr '11

21 Apr '11

To add to Pat's suggestions .... John Papas - K8YSE - records many of the passes and posts the recordings here ==> http://www.papays.com/sat/general.html Another great site for "just getting started" ==> http://web.me.com/clintbradford/Work-Sat/Home.html Clint has a 4 page PDF file with a nice chart on what frequencies to program into your HT to account for the Doppler shifts during the pass. Early morning passes -- 5:00am- 7:00am are much, much less crowded than the ones later in the day when everyone is awake :-) SO-50 is "calmer" than AO-51. AO-51 now requires a 67Hz PL tone (added this week ) The satellite is experiencing longer periods of eclipse - and the batteries are weak -- so the power management software may turn off the FM repeater. The control stations respond as quickly as possible and turn it back on. If you can't hear it -- it may not be you ! A good place to check for "real time" satellite status ==> http://oscar.dcarr.org/index.php As Pat suggested -- check the AMSAT satellite status page ==> http://web.me.com/clintbradford/Work-Sat/Home.html HOPE-1 aka HO-68 - you can hear the CW beacon -- but the FM repeater is down .. I have not heard the ISS FM repeater on lately -- but the APRS digipeater is usually on 145.825 try pushing some packets up to the ISS and then check this site after the pass ==> http://www.ariss.net/ It really is lot's of fun --- Bruce WA3SWJ

Try an FM Repeater in the Sky
by Pat Kilroy 21 Apr '11

21 Apr '11

Here's something to try this beautiful weekend! Including the International Space Station, there are at least SIX satellites operating in orbit with an FM repeater built in. Wanna try to listen for some with me? Listen on your 2-meter radio. If you have a dual-band with 440 MHz FM then you can talk too. (But we'll talk more about talking later. Let's see if we can hear the sats first.) Suggest a repeater around the Washington- Annapolis-Baltimore area and we can start some chats about this. Or use the amsat-dc(a)amsat.org to share your findings! Maybe start with the ISS, whose primary down- link or output is on 145.800 MHz FM. The other frequencies can be found in many places, including: FREQUENICES AND LATEST SAT STATUS http://amsat.org/pipermail/ans/2011/000507.html and more info all around this link: http://www.amsat.org/ Print out this message with the chart below for the satellite schedule. Make sure the schedule is printed in Courier or Courier New, font size 10, to appear nicely lined up in columns on paper. If desired get the free AMSAT booklet "Working the Easy Sats" at the link below. Heck. See even more links below for more scoop for oldsters and newbies alike. Let's do it. Give it a try. Let's hear from you!

Space Day at National Air & Space Museum
by Dave Taylor 03 Apr '11

03 Apr '11

Hello all, Once again, NASM has invited AMSAT to organize displays and activities at Space Day. It will be held on Saturday, 7 May from 10:30 to 3:00 at the Air & Space Museum on the mall. I'd like to hear from anyone who has space-related amateur radio artifacts, posters, activities or anything else they'd like to display. We also need volunteers who can staff our tables (either all day or any part), help with setup and tear down, and various other tasks. There are always lots of interesting exhibits to visit and visitors to talk with, so attending is fun and it helps promote ham radio. ARISS will have various flight-type hardware on hand and also expects a radio contact with ISS. -- Dave Taylor, W8AAS

Celebrate Tuesday April 12: Listen
by Kilroy, Patrick L. (GSFC-5680) 01 Apr '11

01 Apr '11

ARE YOU PLANNING to participate in the ARISSat-1 test on Yuri Gargarin Day, Tuesday, April 12, . . . even a little? Will you be on your own, with friends/ family or perhaps at a school? Tell us about it! (Especially if you need some help.) BACKGROUND All Hams need to know about a special activity unfolding on Tues. April 12. Although the ARISSat-1 is not to be deployed from the International Space Station (ISS) until this summer, NASA connected this educational satellite inside the ISS to an external antenna and will turn it on as a "test" tribute on this historic day. Like most days, there will be six brief ISS passes on April 12. You might be able to hear ARISSat-1 with a very simple radio in the clear on school grounds. Voice messages and telemetry will be heard on the downlink frequency of 145.9500 MHz FM. MORE INFORMATION: http://www.ARISSat.org ISS PASS PREDICTIONS: http://www.amsat.org/amsat-new/tools/predict/ What would you like to do? Ideas? Partner up? Cheers, Pat N8PK n8pk(a)amsat.org P.S. Please forward this message as appropriate.
