Hi Ken, No, I used just the TH-D7 set to 145.825 and set the path to ARISS,WIDE2-2 and use the manual BEACON mode.. It may be ok for your guys in the US as Bon and I discussed a while ago about the amount of traffic here in Europe running high power and beacon to often for the small users like me to get in.. I have tried for months to get my portable packet beaconed.. so good luck..

I am currently using an Arrow antenna. Did you interface the D7 with a computer?

for the uplink you need 145.85 and unproto set to 4aprs v 4xtech I think thats it if i missed any thing some one will pick it up 73 ryan kd8atf ____________________________________________________________________________________ Looking for last minute shopping deals?

Hi, We secured our first sponsor for the LunarX prize; it is CMP the parent company of EE times. In the deal we have a display at the Embedded Systems Conference in San Jose CA about mid April. We will have a 10x10 both and we don't need all that space. If AMSAT is interested in displaying with us, drop me an email. Brian

sending SSET email with UI-View32 via PCSAT
by Alan Sieg WB5RMG 17 Feb '08

17 Feb '08

Greetings and frustrations - I mean salutations... Somehow I had never before used the email function in UI-View, and have not gotten the right magic so far. I tried it on the local 144.390 network, and it worked as expected. I switch over to 145.825, and as before I see my beacons and status packets, but email don't go. I just enter same boxes as for local, even added 'w3ado-1' in digi box, then tried 'aprs,w3ado-1' in the digi box... Hope I'm overlooking something simple, and another UI-Viewer can shine a light for me. Everything looks proper in the debug window. Thanks /;^) -- <- WB5RMG is Alan Sieg * http://wb5rmg.somenet.net ->

SSET trying to work GO-32 on 9600
by David Julian 16 Feb '08

16 Feb '08

I'm trying to send a short e-mail message through GO-32 for the SSET without any luck. On the radio side I'm using an FT-847, 30 el crossed ant on 70cm, 20 el crossed on 2m, AZ-EL rotor with no pre-amps and the tracking program is SatPc32. This set-up works fine for FM & SSB voice at about a 15W TX level. For a TNC I'm using an old l.L. Grace DSP-12. Set in UO-22 mode with the following settings: <UO-22 PKT> cmd:Beacon BEAcon is EVERY 12 x 10 seconds <UO-22 PKT> cmd:BT BText is :EMAIL :[email protected] SSET from New burgh, IN <UO-22 PKT> cmd:UN Unprotocol is CQ VIA ARISS I can receive the downlink on 435.225 without any problem. For the uplink I'm on 145.825. The TX deviation has been set to 3kHz on the low and high tones in the calibrate mode. On a seperate monitor I can hear the TX going out on the beacon. My guess is that I don't have the TNC settings correct. Any help would be appreciated. Thanks//Dave WB9YIG --------------------------------- Looking for last minute shopping deals?

I think that's the problem. The uplink for GO-32 is on 145.85 for normal APRS packet(tocall of APRS or APxxxx) and 145.93 for Mic-E formatted position reports with position comment set to Committed or higher (D7 or D700).. Please see details on: http://www.ew.usna.edu/~bruninga/GO32-ops.html And also, be satisfied if you see your email in the downlink, because I dont think we still have enough IGates listening to make sure it gets into the Internet system. Hope that helps. Bob, Wb4APR

Hello, are the informations about european qsl manager on the following page correct? http://www.arrl.org/ARISS/ariss-qsl.html I found a different address for F1MOJ on www.qrz.com. Btw, I'm sending a QSL for a 2 years old contact, better late than never I think :-) Thanks and 73 Francesco IZ8DWF

Re: Since We Are Off Topic Somewhat....

Bill Jones asked: > While discussing this topic of orbital decay, I wonder if someone would > comment on the apparent anomoly whereby a sat in leo that encounters drag > actually speeds up (since as it's altitude decreases, the orbital speed > increases), and how this might be a factor in the comparison of the heating > effects on an object that decays gradually from orbit vs an object like the > shuttle that is taken out of orbit by actually reducing it's speed with > thrust. I have my own intuitive theories on this but would like to hear more > informed opinions. What confuses people is that the orbital PERIOD (minutes/orbit) decreases with drag, and hence its reciprocal (measured in units like like orbits/day) increases. As the satellite gives up kinetic energy to heat, it falls into a lower orbit, where it must move faster. The relation is that the square of the period is proportional to the cube of the size of the orbit. All this is is embodied in Kepler's 3rd law (see http://en.wikipedia.org/wiki/Kepler%27s_laws_of_planetary_motion) which the Wiki states as: * "The squares <http://en.wikipedia.org/wiki/Square_%28algebra%29> of the orbital periods <http://en.wikipedia.org/wiki/Orbital_period> of planets are directly proportional <http://en.wikipedia.org/wiki/Proportionality_%28mathematics%29> to the cubes <http://en.wikipedia.org/wiki/Cube_%28arithmetic%29> of the semi-major axes <http://en.wikipedia.org/wiki/Major_axis> (the "half-length" of the ellipse) of their orbits. This means not only that larger orbits have longer periods, but also that the speed of a planet in a larger orbit is lower than in a smaller orbit." An animated "movie" of Kepler's 3rd law can be seen at http://people.scs.fsu.edu/~dduke/kepler3.html <http://people.scs.fsu.edu/%7Edduke/kepler3.html>. 73, Tom
