Cable question
by Ollie Eisman 10 Jan '08

10 Jan '08

Hi everyone, I would like to use a G-5500 rotor on top of a 20' telescopic mast with 2m and 70cm sat antennas. Assuming this isn't a bad idea to begin with, my next goal is to find RF cables that will work best with this type of tower given it will be raised and lowered frequently, thus causing a lot of extra cable flex. (I am not even sure of the best way to run cables up the to rotors when the mast is telescopic - ideas?) I am looking at 20+' for the tower plus another 50' or so back to the shack. An suggestions? Love those covenants... :) 73, Ollie, AJ1O

Folks, I noticed some folks use the logo on their web sites. Is this allowed freely or must one obtain written permission from AmSat? 73, Ed KC9GWK Grid EN52 AmSat Member

Thanks everyone for your help. Google keep pointing me to http://groundstation.sourceforge.net/gpredict/index.php but as was pointed out, it was under the the older 0.8.0 version and not the newest 0.9.0. Duh !!

LVB tracker questions
by Andrew Rich 10 Jan '08

10 Jan '08

1. Some other designs use a variable supply to calibrate the rotator position - what does the LVB do ? 2. Does the LVB tracker get a command, move the antenna around, and shut out any other commands, untill it gets the first command sorted ? 3. What does the LVB tracker show on the screen ? 4. What protocols does the LVB tracker work with ? 5. I heard mention that the LVB does a few samples of the A/D to make sure it has a valid result from the pot's 6. The cct diagram shows two diodes, connected to each az and el a/d input, what do they do ? ---------------------------------------------------------------------------- Andrew Rich VK4TEC vk4tec(a)people.net.au http://www.tech-software.net

OLPC positions and MESH-ing
by Bob Bruninga 09 Jan '08

> In the DC area, I think we have several > Hams with XO's. Maybe we should schedule > a meeting and show-and-tell so that everyone > can benefit from the fruits of our efforts? Actually, I would like to build a map of all HAMS with OLPC's to help us play and possibly MESH together.. The map will include both your home and work locations which are two places where you might have your OLPC laptop for meshing. If you are retired, then include any other place you may frequent. Just email me your CALL, and LAT/LONGs for both of your locations. If you have other daily locations you may add them too. ALso indicate how many OLPC's you have. Here is the preferred format: WB4APR:3909.12N/07629.34Wl Home, with access to 3 OLPC's The LAT/LONG is in DEG and decimal minutes. The two spaces after the decimal points are for hundredths of minutes. If you replace them with two spaces, then your position can remain ambiguous to the nearest mile, if you like. The "l" (lower case L) after the W is the laptop symbol. Everything after that is free text to describe your OLPC. Those that are into APRS can go ahead and just change your normal APRS station to the LAPTOP symbol for the next week or so, and I can capture your posit that way electronically. > TO make it easy to compute the centroid > of local OLPC's, everyone could beacon > their position on APRS using the LAPTOP > symbol with a note about their OLPC. > Then we can pick the centroid to plan a meeting... Thanks! Bob, WB4APR

Hi Everyone, We're coming up on the time when I need article submissions for the Jan/Feb 08 Journal. If you have an article to submit I would love to have it as soon as possible. The last couple of issues have been late going out due to lack of content and slow submissions. I would appreciate your help in getting something to me quickly if you have an article. Thanks and Happy New Year! 73, Ed Long, WA4SWJ Editor, The AMSAT Journal
