Last 2\nweeks I'm monitoring\nRS-15 and I tryed several times (always in Sunlight), by using all possible\nUplink frequencies\n(145.858-898 & 958-998) without success. A few mins ago I tryed also (after\nyour Email, orbit #48419). A big ZERO once again!\n\nRS-15's beacon usually is booming on my receiver and I'm thinking that\nBeacon's output\nPower is just 0.4 - 1.2 Watts, so the downlink signal should be \"super\" with\n5 W (max) output of Linear Transponder downlink. Unfortunately that did not\nhappen. Never ! I remember my efforts at early '95, when this bird was new\nand just 3-4 times I had heard my downlink signal very weak, with extremely\nstrong QSB and as I know that was common for all users.\n\nYesterday, looking for RS-15 reports around Internet I found very\ninteresting the following page, where Mike, KF4FDJ reports succesfull QSOs\nwith 4 other stations (end February 2004).\n\n So we can't talking for RS-15 \"reborn\", it was always out there\noperational but definitely it is not an \"easy Bird\".\n\nhttp://www.mydarc.de/df8gh/RS-15.htm\n\n( The above page is also very informative about the difficulties of RS-15 &\nrelationship between Beacon - Transponder's activation.)\n\n\n\n Several days ago Gary wrote about 100 KHz Uplink-frequency \"jumping\" Up,\nbut that is not confirmed now from you dr Pedro. If used 145.875 KHz for\nyour uplink , we have another scenario which says that, the frequency did\nnot \"jump\" but it's stable. Strange.\n\n Well, I'm a little-bit confused with all.. I would like of course to have\nanother Bird in good shape, but have we?\nor it was just a random (& lucky) operation of RS-15, like a flashback and\nin practice its an unreliable, non useful bird for the most Hams?\n\n I wonder... (but I've my fingers crossed & I wish you have right !)\n\n73, Mak SV1BSX\n\nPS: BTW you wrote about 25 W Uplink power. What is your EIRP?\n\n\n----- Original Message -----\nFrom: lu7abf\nTo: [email protected]\nCc: [email protected]\nSent: Thursday, September 28, 2006 7:01 AM\nSubject: [amsat-bb] YES !! RS-15 is alive !\n\n\nYES !! RS-15 is alive !\n\nReading a recent report on AMSAT-BB from Gary deMunbrun WA4RKS about RS-15,\nmove me to try. Tks Gary!\n\nI tried on several passes, I always heard the intermitent carrier at 29.352,\nbut no repeat of my uplink, trying either on official 145.858-98 or on\nsuggested 145.958-98.\n\nAll of tries were made with RS-15 on her night. But today I gave her another\ntry. This time RS-15 was sunlight on a pass that lasted 20 minutes on\nSept-28 00:24 to 00:43 LU Time. I could uplink first CW and after SSB and\nhear it back !!!!, despicte the fact that I'm only using 25 W from FT-736 on\n2mts and a 2m turnstile !!\n\nFrequencies I operate where: Uplink 145.875 , downlink 29.374 with good\nsignal return about s3.\n\nUnfortunately no one to try a QSO. RS-15 is amazing, with 2000 Km height,\npasses can last up to half an hour ! even earth coverage is quite broad !\n\nSo, looks that we have had a new child reborn, coming back to life from over\nten years ago.\n\nYou can find on http://www.amsat.org.ar RS-15 passes precalculated for your\nlocation and on your time, for a quick RS-15 .\n\n73, Pedro LU7ABF [email protected]\n_______________________________________________\nSent via [email protected].
