>> ... I don't want to be a troublemaker ... Since when, Luc? Is this a New Years' resolution of some sort? >> ... did you ever think your A148-3S was developing some issues with the years? Naw ... I always clean the exposed parts of antennas like this one, and spray 'em with marine spar varnish for protection from the elements (pun intended). Both antennas - my Cushcraft A148-3S and the WB2HOL Tape Measure Yagi - are rated at about 7dBi - well, at least that was when Cushcraft was making the A148-3S. I don't know what MFJ's version will be rated at. OOOPS - We weren't going to cause trouble ... (grin) Clint Bradford http://www.k6lcs.com

Merry Christmas and Happy New Year from Amsat-China
by Alan Kung 23 Dec '09

23 Dec '09

Hello all, On behalf of Amsat-China and HO-68 amateur satellite project Team I would like to express my sincere thanks to all radio amateurs who reported the communications status of HO-68 satellite in the past few days. I would also like to express my sincere thanks to all individuals and organizations for your congratulations. I must say sorry I am not able to respond to each of the reporters, but your reports are very valuable for our analysis of status of the satellite. Thank you very much for your participation in the in-orbit satellite communications test of HO-68 and submited detail reports. I wish you a happy holiday and hope HO-68 amateur satellite will be able to bring you a new fun! 73! Alan Kung, BA1DU HO-68(XW-1) Project Manager CEO of Amsat-China

HO-68 (changing modes, commands)
by PY2ZX 23 Dec '09

23 Dec '09

Hello, On the weekend, during one of the XW-1/HO-68 passes schedulle for change the "beacon/TLM only" to "beacon/TLM + FM repeater" mode, It was clear the temporarily interruption of TLM data flow for their quickly return from the beggining of the TLM frame with new status, exactly on the time combined. So CE3RR was well heard in FM downlink. My neophyte question is: The satellite was over Chile that time. Do we need an earth ground station in South America, inside the footprint of the satellite, to send the operational changing command to the bird for HO-68 real time answer to the request or only the Chinese controler sent the command, for satellite store the information and, at appropriated time, far way from Asian footprint, HO-68 active the ordered?

Another Bradford DUH! Moment
by Clint Bradford 23 Dec '09

23 Dec '09

I am preachin' to the choir here with this post, I am sure. But since Southern California was under STORMWATCH again last night (we're expecting at least 0.03" of precipitation), I decided to build one of those cheap "tape measure 2M Yagi" antennas from plans seen all over the Web. I mean, I mention them during my satellite presentations as an affordable entry into high-gain ... I have a couple links on my Work-Sat Web site for plans ... I can see in theory where they should work - but I've never built one myself. So I stuck the PVC pipes together ... soldered the matching element ... straightened it all out, and took it outside for a test. OH MY GAWD. This is something that EVERY ham should do. What a dramatic increase in a handheld's performance a couple dollars' worth of stuff can accomplish! I heard a NOAA WX station (technically, out of range for this 2M Yagi) in San Diego that I have never heard from the house before. Every repeater of the six I immediately hit were received more clearly than with even the best of HT antennas ... and as good or better than my Cushcraft A148-3S (retailing for sixty bucks). Sorry - have to stop writing. I am way too old to get this excited about this hobby ... Clint Bradford, K6LCS http://www.work-sat.com

AO-7 Not Active
by ps8rf Piraja 23 Dec '09

23 Dec '09

Hello, The satellite AO-7, is not active, I could not listen to the Beacon or my return in mode A and mode B today at 19:55 UTC. Looking at the list of website logs and Oscar satellite status, the information is that the satellite was turned off after 13:00 UTC. Let's hope it's nothing serious and that soon the AO-7 is reinstated. http://www.planetemily.com/ao7/ao7log.php http://oscar.dcarr.org/ 73 Piraja, PS8RF _________________________________________________________________ Navegue com segurança com o Novo Internet Explorer 8.
