Has any Amsat member experience using the LVB tacker with Yaesu G1000DXC and KR-500 rotators? Is it easy?possible?Or impossible ? With thanks Andy VK3AS ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] FW: Sumba Test Schedule

Hello Piero, The times reported on the website of SA AMSAT ( http://www.amsatsa.org.za ) and with the time told by Mike, DK3WN (thanks Mike) do not correspond with the schedules resulting from my simulations. For the Sumba not go active on Europe the satellite had to be activated and

Hi Piraja, Most probably they just upload a job to Sumbandila to be executed at the specified time. That is done by the control stations in SA. Just speculation on my part. Have a nice Sunday. 73 OZ1MY Ib - Original Message - From: ps8rf Piraja ps...@hotmail.com To: amsat-bb@amsat.org

Interesting visual program! But, I don't see a way to offset the two antennas in space, only in phase. I agree that if you put two antennas in the same plane and 180 degrees out of phase, they will nicely cancel each other out. But if they are offset, then the linear signals will cancel,

[amsat-bb] Which rotor control to use?

Hello guys, I was wondering what kind of hardware to use to control my satellite rotors. I have the G-500A elevation rotor and the G-650C azimuth rotor. My only com port is connected with my FT-847 for doppler correction via HamRadioDeluxe so it must be something via the USB port. Thanks! Eric

Kim, AC7YY has taken a survey of the APRS-IS to find out what other areas have Satellite Tracking engines that are putting out live satellite-objects onto the local APRS information channel. It appears there are only two other USA systems and the rest are overseas. CALL LATITUDE K3PDK-1

Hi Drew et al I monitored the last pass with three radios.  On the standard 70cm downlink.  A three foot primestar dish with transystem 3731aa downconverter to a TS700A transceiver.  Finally a portable 20 turn helix with a IC-W32a connected to a Keps 13-LNC2-PH downconverter.  The primestar

Hi Greg, KO6TH You are right. Imagine to get two folded dipoles horizontally mounted over the same boom at a distance of 1/2 wave in space (180°) They are feed in phase and we are looking along the boom in one direction. First case: The rear dipole has the inner conductor of the feed line
