Ground plane vs. Eggbeater vs. best omnidirectional antenna?
by Bill Dzurilla 10 Feb '08

10 Feb '08

Hi, Homebrewed a K5OE Eggbeater II and tried it out today, but did not notice much, if any, improvement over the 1/4 wave ground plane I had been using. Both were 30' high, 50' of 9913, no mast-mounted preamp. Can hear AO-51 OK but can barely hear AO-27 with both antennas. Is this as good as it gets with an omnidirectional antenna? Can AO-27 be heard well with the M2 eggbeater? With a mast-mounted pre-amp? Is there a better omni than the eggbeater? I hear AO-27 much better with an HT and an Arrow. 73, Bill NZ5N ____________________________________________________________________________________ Looking for last minute shopping deals?

Linear transponder without duplex?
by Bill Dzurilla 10 Feb '08

I know full duplex is the best, but is there a practical way to work VO-52 and other linear transponder birds w/o duplex? 73, Bill NZ5N ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Well as the bird went over on its last pass I didn't hear it either. So I am also wondering about that. Thanks and God Bless Rev. Carl Cook N4ERO EM96DV

NO-44/PCSAT Crash?
by John Marranca, Jr 10 Feb '08

10 Feb '08

It appears as though for the past 3 orbits, PCSAT has crashed...as evidenced by its PCSAT-11 on the downlink. Hopefully she'll be brought back to full health soon. Good Luck Bob!

Listening for AO-51

Hi to the Group: Haven't heard AO-51 for the past several passes. The control team news web page is posted with a extract warning "first argument should be an array in /var/www/docs/amsat-new/lib/amsat_sql.php on line 115". Satellite problem?

Re: "BlueMarble" maps on SatPC32
by Wayne Estes 10 Feb '08

The best way to add "Blue Marble" maps to SatPC32 is to download and install the latest version, 12.7. With a single mouse click you can switch between the old political map (showing country boundaries) and the new Physical Map (satellite composite image from NASA's earth observatory). http://www.dk1tb.de/indexeng.htm On the web page you can see screen captures of the Political and Physical maps, for comparison. Be sure to REGISTER your downloaded copy of SatPC32 with AMSAT. All the money goes to support AMSAT programs. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik

way off topic

Hi to the list , Does any one have a data sheet or a link to one, for an MC1460 voltage regulator? The voltage regulator board in my krautkramer USIP11 ultrasonic test set has failed and I suspect the above IC but I have no info at all on this IC, an extensive google search has revealed no info. Maybe some one has this info. My motorola data books only go back to 1979, and I think this IC is circa 1970.... The unit was made in 1976 ( and has been extremely reliable...) most of the components in it are from the early '70's. shades of AO7! Any replies off list if you prefer, Thanks Don, ZL1THO

Ground plane vs. Eggbeater vs. best omnidirectionalantenna?

Bill said : > Homebrewed a K5OE Eggbeater II and tried it out today, > Is this as good as it gets with an omnidirectional . . . ? I have also recently built EB IIs for 144 and 435. (I actually built them for the recent VHF contest, hoping to also use them for satellite...)(there are not many choices for horizontally polarized, omni-directional antennas - these worked great in contest !! ) My tower has not erected itself after most recent cross-country move, so I have limited choices. Currently these two EB IIs are in the attic. Each one has an ARR 20dB preamp. Last weekend was the first chance I have had to try any satellite, and somehow managed one contact each via ISS cross-band, then AO-16, then AO-51, then on VO-52. I was pleased .!. This with a barefoot FT-736, 60 feet 9913 on each antenna, in the attic. I will be back on VO-52, as I really miss linear transponder/SSB combo. In the early 90's I was fairly active on AO-13, and the Microsats. I had multiple antennae on the Az/El rotor, but without all that now, the EB IIs are a great improvement over 1/4 wave, for me at least.
