This last pass of AO-7, I could swear I heard some FM sigs on a downlink freq of about 145.950. This was at the same time I had AOS of AO-51. I don't see a connection, maybe I just need a nap. Anyone else hear the same? -- 73 Bob W7LRD AMSAT member 28498 Seattle

Newbie help on Transverter projects (70cm, 144)
by ke5eup＠ke5eup.com 06 Jun '07

06 Jun '07

Hello everyone, I have joined Amsat and this is my first post. I am looking for home brew transverters. I have a SDR 1k withthe internal 144 DEMI that gives me 28 IF out. There is no way I can afford to buy transverters from DEMI or Elecraft. I am on very limited funds (SS). I can afford to make PCB's and buy parts or have PCB's made. I looked at farcircuits and googled. I founf plenty of stuff for 5 GHz and up. I would like to build a 70cm first and then a 144 to use my SDR in my new adventure into the world of sat operation. If anybody has gerber files or has built one (especially 70cm), I could use the help. 73's -- Thanks, Al KE5EUP BCARN,KCARC,ARRL,TAPR,AMSAT,HPSDR ARRL WTX ARES EC Callahan County Races CLO ALT 42-059-D Callahan County

AO-16 MIA?
by W.J. Ubbels 06 Jun '07

06 Jun '07

Hi all, after reading the posts about AO-16 apparently going silent, I checked the data from the Delfi-C3 backup groundstation, which has been set up at Eindhoven University in the south of the Netherlands by Jeroen Vreeken, PE1RXQ, he did a great job automating the station using his own developed software. As a test, he let the station track AO-16 continuously for a couple of months since the beginning of this year, and a quick examination shows that telemetry stopped around the 22nd of May. (We both have not been able to manually track AO-16 and listen for a signal in order to make sure it's not a problem in the groundstation which could be since the rotor does not work 100%, but reading the other reports about AO-16 on the BB it seems that it has indeed stopped transmitting) On the following page you can find the telemetry files from the station at Eindhoven: http://esther.esrac.ele.tue.nl/ao16/ note that of all passes, flac (audio) files are available, as well as raw kiss files (.kss) and ascii files (.asc) We used AO-16 extensively as a nice test signal generator since it produces AX.25 1200 bit/s BPSK just like Delfi-C3 will do soon hopefully:) Hope the command ops can get this bird working again! By the way, we are working hard to complete Delfi-C3 for her launch, and are learning a lot from integration of the spacecraft! 73 Wouter Jan PE4WJ -- W.J. Ubbels MSc.

Hello folks. I am going to use Satpc32 in the QRP settings. I am using "Vista". And when I add a line to the "Doppler.sqf. It won't Let me save the changes. Trying to put in the starting freqs for uplink/downlink so software will track. Anyone know how to save the change in "Vista". In "XP" it was simple, just clicked on save and the change was there. Thanks Don...w2xb

Space Shuttle Launch - Need some freqs.
by Paul Lenharr II 05 Jun '07

05 Jun '07

Hello all. I will be leaving on Wednesday for the 14 hour drive to FL to watch the shuttle launch from the NASA causeway. I was wondering if anyone had some updated repeater info for the area. I am looking for either a repeater or simplex frequency that I might be able to use to listen to the launch audio with on my HT during the launch. I read somewhere online about a repeater or repeaters that broadcast the audio live but I cannot find the site again. Also any info on mission frequencies that are used would be helpful. Thanks in advance. 73, -- Paul D. Lenharr II (KB3NDS) VUCC #1522 - 50mhz Six Club Member #2350 Skywarn Spotter # CS-19 "Pain is temporary, Pride is forever!"

Any way to get DIGIPEATING enabled? Then anyone with a D7 or D700 could make 2 way APRS contacts on Field Day! I used to enjoy demonstrating my D7 walkie talkie with a tiny 3 element hand held beam, and copying KO-23 standing by the pool at the 1998 AMSAT meeting. Bob, WB4APR

Hello Folks, Well I figured out how to change and save the settings in Doppler.sqf. You go to properties and click on security and check all the boxes . It then allows you to save the new changes. Its "Vista's" way to keep you from making the wrong change..(ugh!) Don...w2xb

I moved from there 10 yrs ago, but the Titusville repeater always had the Shuttle audio on it. I can't immagine it's changed -------------------------- Sent from my BlackBerry Wireless Handheld -----Original Message----- From: amsat-bb-bounces(a)amsat.org <amsat-bb-bounces(a)amsat.org> To: amsat-bb(a)amsat.org <amsat-bb(a)amsat.org> Sent: Tue Jun 05 18:57:09 2007 Subject: [amsat-bb] Re: shuttle rebroadcast There was a question posted of how to receive the shuttle rebroadcasts in the space coast area. I was hoping a local would respond but this information follows from W4UFL, a club member who is staff here at UF in Gainesville. I plan on using the info since as luck would have it I depart on a cruise from Port Canaveral about two hours before the launch. I'll bring along a HT and videocamera. If there is not a delay we'll have an ocean view! Jay, AA4FL Faculty Advisor, Gator Amateur Radio Club at UF, club station W4DFU Visit our Website at www.gatorradio.org <http://www.gatorradio.org/> and listen for us on the birds <<Last time I was there, it was on 146.910 or 146.940 but I'm not really sure what the current freq. is. Several repeaters usually carry it. I have heard it is on UHF as well as VHF. Scanning has a good chance of getting it since the launch coverage is usually active. There are some web sites but I don't know how fresh they are. http://home.cfl.rr.com/scanner/brev1.htm 146.940 146.340 103.5 NASA Select Audio - Space Shuttle Rebroadcast - Merritt Island If you have ATV, you can even pick up NASA-TV rebroadcast over Amateur Television. http://viaoz.com/lisats.org/ You can hear the NASA Select Channel on a "radio scanner" of the type sold at Radio Shack. Tune to 146.940 MHz for the Merritt Island ham radio repeater where John K4GCC has a line into the Space Center. A backup frequency is 147.135 MHz. The Titusville "chat" frequnecy is 146.910 MHz, and if you're a ham operator yourself, call N4SCY on 146.970 MHz, and I'll be happy to talk you into a good viewing site. http://spacelaunchinfo.com/countdown.html>> _______________________________________________ Sent via AMSAT-BB(a)amsat.org.
