EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

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...

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

Solar Ham Radio Interference
by Robert Bruninga 20 Nov '16

20 Nov '16

Not Satellite related, but people often ask about any RFI from my solar arrays at home. Interest stems from an RFI issue in April QST and my letter in Sept 2016 QST. Well, FINALLY, the jury is in. For the first time since installing solar, I finally got all my full-sized dipoles up in the air again. And listened with the arrays on and off. Yes, I have inverter noise about 12 dB above the noise floor every 38 kHz on 80 meters,. But couldn't really find anything on 20 meters. I did not do a thorough search, but enough to finally say, "yes, there is some noise..." I post this because my 16kw of arrays are conventional series string arrays and much quieter than the "optimizers" on every panel all over the roof noted in the April QST article. I always thought my string array was quiet, but now I have some data noted above. This could easily be fixed with some clamp-on ferrites down in the basement on the wires going into the inverters... But for my rare HF operating, the solar AC disconnect switch is about 3 feet from the kitchen door. Easy enough to pull if I want HF silence. I could also install a 40 amp disconnect relay from a switch in the shack... But with my rare operating style, I'll probably do nothing. Of course it is perfectly quiet at night ;-) It took me 6 years to get around to this test, so don't hold your breath waiting for me to add some clamp-on filters to the inverter wires and see what that does. For those into solar, come join us on SolarDIY(a)yahoogroups.com Bob, WB4APR

ARISS Meeting Information
by Frank H. Bauer 09 Nov '16

09 Nov '16

All, Those who have expressed interest in the ARISS meeting previously have received the latest ARISS meeting information. I am including it here for all on AMSAT-BB because there was a query about it here. Since BB will not accept attachments, our "near final" draft for our ARISS meeting in Houston can be downloaded at: https://www.dropbox.com/s/7b156pcxxrjdjon/ARISS-I%20Agenda%202016%20Houston- Rev%208.pdf?dl=0 As you review this, I think you can see that we have some really exciting topics that we will be discussing and working through, as a team. Most importantly, we will be celebrating our 20th anniversary as a team. For those not aware, 20 years ago, in November 1996, an international group interested in installing and operating a ham radio station on the ISS met at the NASA Johnson Space Center in Houston and, per NASA's direction, formed an international working group called ARISS. And the rest is history!! Because we have so many things to address at our ARISS-I meeting, we have divided our discussions into 3 primary categories: 1) Hardware Development, 2) Education and 3) Sustainability and Funding. As you can see in the agenda, we will be conducting two sessions simultaneously like is done in a conference. We will also have plenary sessions, where the entire team will attend, to discuss topics that impact the entire, world-wide team. If you are still interested in attending the meeting, you are welcome to come. Please let me know (directly) of your interest. I thank you all for your interest in and support to our magnificent program. It is amazing what we have accomplished in 20 years! It will be exciting to see what we will do in the next 20!! 73, Frank Bauer KA3HDO AMSAT V.P. for Human Spaceflight Programs ARISS International Chair

SatPC32 (12.8c)-icom 910-subtone.sqf
by LB2TG Paul 01 Nov '16

01 Nov '16

Hello. Can anyone help with the syntax in the subtone.sqf for ic-910? I have tried "almost everthing" but the subtone are still in the standard value 88.5 I can set it manually to 67.0 and 74.4 for SO-50. I also see that I have to change "NOR" and "REV" manually. Maybe some can write this line correct for Icom IC-910? SO-50,67.0,??? SO-50,74.4,??? When I connect, and change the settings for the rig, my old TS-790 works great. 73, Paul LB2TG

Re: [amsat-bb] Kenwood TH-D74A for Satellite Work
by Clint Bradford 31 Oct '16

31 Oct '16

NO - The new US$650 Kenwood THD-74a will NOT perform in true, full-duplex mode like the '72a. And will NOT be firmware-upgraded to do so. There is a rumor that Kenwood might be considering the 'D72a as a "replacement" for the TH-F6a - again, just a rumor, but from a good source. Want a SINGLE rig to perform U/V and V/U modes for the FM birds? The Kenwood TH-D72a at US$390. I am trying to work a couple more passes with the HRO-distributed Powerwerx UV-9D(Plus) on SO-50 - to see how well it does on both U/V and V/U FM voice modes. Clint Bradford K6LCS http:/www.work-sat.com PS Don't forget the Palm Springs HamFest on Saturday, February 4, 2017, being held at the beautiful Palm Springs Air Museum! Satellite presentation at 11am in the Major General Ken Miles Aviation Science Center. SO-50 pass right before that ... plenty of ham history, aeronautical history, and plenty for the family to do for just $8 admission!

Kenwood TH-D74A for Satellite Work
by Les Rayburn 31 Oct '16

31 Oct '16

I’m sure this must have come up before, but unfortunately I missed the discussion. Curious if anyone on the list has tried the new Kenwood TH-D74A for satellite work on the FM birds? Is the rig truly dual-band like the TH-D72A? 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL EM63nf Member WTFDA, IRCA, NRC. Former CPC Chairman for NRC & IRCA.
