What birds

I have spent all day getting my Icom 910h,,SatPC32, and my Yaesu 5400B all back working again and tracking. But now what birds are there up there that are still active? In the past I worked AO-27, AO-51, FO-29, VO-52, AO-7, and SO-50. Which of these are still operational and any new ones? Thanks Nels W0TUP North Dakota

G5500 Rotor motor Question
by Mike Hoblinski 28 Apr '13

28 Apr '13

Anybody know what the rpm of the AC motors are. I know from the Yaesu specs that after all of the gear reduction they list EL as 67 seconds for EL and 58 Seconds for AZ. I would like to experiment with an AZ and EL system but like to see what RPM the motor starts out with and how much torque to get the final results. They show Elevation at 101 FT-LBS and AZ at 44 FT-lbs. I have looked around to see if somewhere the specs are available for the motor but have had no luck. I have seen quite a few pictures of rebuilds of that rotor with part number and have a manual that shows parts. Mike Hoblinski N6IMF

satpc32 etc

Thanks to many and Dave KB1PVH I can now input keps in my computer all by myself. I read this in the weekly AMSAT bulletins The Castor 30 second stage motor, built by ATK, ignited for a burn lasting two-and-a-half minutes, accelerating the rocket to more than 17,000 mph. Engineers declared the rocket reached orbit, and the upper stage deployed a 8,377-pound block of aluminum designed to mimic the mass characteristics of the Cygnus spacecraft, which will take the dummy payload's place on the next Antares launch. Why does this want me to pull out what little hair I have left?? 8,377Lbs! I'm sure I am missing something, what did AO-40 weigh? 73 Bob W7LRD

Help! What does this mean?

Got this tweet from Exa. What is a 160Db station? You need VIDEO transceiver on 910 with 25Mhz BW to hear and see it and at least 160dB gain, please confirm I expect this means total amplification including the radio. Still nothing heard

Pegasus Nee-01? anyone else listening?

Nothing heard on two passes. Not sure as I all I can hear are what I think are timing sigs from cell towers. They had a direct pass over HC on orbit 7.

Ray, An update on the identifications of the new satellites: 39131 2013-015B OSSI 1 39132 2013-015C DOVE 2 39133 2013-015D AIST 2 39134 2013-015E BEESAT 3 39135 2013-015F SOMP 39136 2013-015G BEESAT 2 NEE-01 (Pegaso), Cubebug 1 (Capitán Beto) and Turksat-3USAT are in the group 39151 2013-018B, 39152 2013-018C, and 39153 2013-018D. Which satellite is which object is still to be confirmed. Two-line elements are available for all these satellites. The three PhoneSats from the Antares launch have now decayed or are about to decay. 73, Nico PA0DLO On 2013-04-26 04:35, Ray Hoad wrote: > A lot of activity in the last week! > > The week we have added the following cubesat satellites: > OSSI-1 Cat# 39130 Beacon on 145.980 MHz CW and 437.525 MHz 1k2 > also has LED optical beacon in morse code > BEESAT2/3 Cat# 39131 435.950 MHz 4k8 GMSK (two separate satellites > real close together for now) > SOMP Cat# 39135 Downlink 437.485 MHz including CW, 1k2, 9k6 BPSK, > AX25 FSK and AO40 type standard 400bit/s BPSK > GRAHAM Cat# 39142 Phonesat 437.425 MHz using smartphone computer, > using batteries only only good for about a week > BELL Cat# 39143 Phonesat 437.425 MHz using smartphone computer, > using batteries only only good for about a week > ALEXANDER Cat# 39146 Phonesat 437.425 MHz using smartphone computer, > using batteries only only good for about a week > > Go to http://ww2.amsat.org and click on "AMSAT NEWS SERVICE WEEKLY > BULLETIN" to get details on these new cubesats. >
