[amsat-bb] ARISSat-1 What a Ham Radio Achievement!
Hi Gang, I excitedly tuned my base station, connected to a dual band Ventenna on the roof, to the downlink frequency of 145.950 mHZ this morning as I tracked ISS on a pass over North America. I'm in Southern New Jersey. I was amazed to be able to hear the initial greeting female voice from this special bird! On the following pass I used a portable HT and Arrow Antenna out on the lawn and copied ARISSat-1 5X9! Thanks to all who made this possible and all who are helping us enjoy this wonderful hobby!

[amsat-bb] Duplexer / 847 / Preamp Question
Guys, I want to use an FT-847 with a mast mounted SSB preamp and a single feedline antenna (Cushcraft A270-10S) that I already have mounted on my tower. Can I send the DC for the preamp up through the coax and still use a duplexer? I have checked the continuity of a Comet CF-4160 duplexer and the 1.3-170MHz side appears to be isolated from the 440 side. Since there is direct continuity on the 1.3-170MHz side of the duplexer I would run the DC for the preamp up that "side." I really don't want to blow up my 847 by doing something foolish so any thoughts, cautions etc. welcomed. 73 de harry, W6DXO ___ Sent via amsat...@amsat.org.

[amsat-bb] Antennas: How High?
Guys, I want to upgrade from my hand held Arrow to something permanently mounted outside with and Ele/ Az rotor. I have a single story home with roof peak at about 22 feet. I can easily mount a 10' - 20' mast directly outside the shack anchored in concrete and bolted to my roof eaves. If I use two masts sections I will get a net height of about 17' which means I will be "looking" through my roof on the lower easterly orientated passes. Gaining the additional height to completely clear the roof line will be increasingly problematic. How much should I be concerned about this, etc? I'd like some real world feedback / suggestions. Thanks in advance. 73 de harry, W6DXO ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

[amsat-bb] Elk Antenna ?
Guys, I want to mount the Elk dual band 144/440 antenna up on my 85' tower. Can I get away with a fixed elevation of about 30 degrees and horizontal polarization? I recognize that this is a compromise, but I'd like to avoid the additional complexity of dealing with an azimuth rotor. Any thoughts appreciated. 73 de harry, W6DXO ___ Sent via amsat...@amsat.org.
