"-" kEPS are OK at the second the TX start transmitting with less distortion. After 30 seconds "near one minute" the TX shutt down again for a brief moment and to resume back again transmitting with a bit more distortion.

Re: Delfi-C3 RASCAL tuning & TLE's
by G0MRF＠aol.com 01 May '08

Hi. Here in London I can only manage to monitor evening passes. All of these have Delfi-C3 emerging from eclipse shortly before, or during the pass. So far it's been there on every occassion. I managed to get a little telemetry last night, but only enough to show the computer has had 2216 attemps at booting up. With about 40ish orbits that averages 50 tries per orbit So, immediately exiting eclipse seems the best time to get good results. When starting RASCAL you appear to need 3 consecutive packets on frequency to sync the receive software and to decode the last packet as a line of data. Thanks David In a message dated 01/05/2008 05:27:37 GMT Standard Time, lucleblanc6(a)videotron.ca writes: > Hi all, > > we have added a section to our RASCAL tuning guide in order to make > achieving sync in RASCAL easier, see > On all the morning pass DELFI C 3 remain silent over North eastern America.

Hi! On Saturday, 3 May 2008, the Cochise Amateur Radio Association (CARA) will host the annual Larry Warren Cochise Hamfest in Sierra Vista, Arizona (grid DM41vm). The hamfest starts at 7am local time (1400 UTC). CARA has more information about the hamfest at: http://www.k7rdg.org/2008hamfest.html As part of the hamfest, there will be an AMSAT table with merchandise and satellite demonstrations. Local hams Jeff K7WIN and Bill K7WJS, assisted by Larry W7LB from Tucson and me (driving down from Phoenix), will be there to answer questions related to amateur satellites and also have on-air demonstrations using the AO-51 and SO-50 satellites during the morning. Thanks to the CARA, our on-air demonstrations will be done using the club's callsign K7RDG. If you hear us on the Saturday morning AO-51 and SO-50 passes, please give us a call. Between passes, we will be reachable on K7WIN's 70cm repeater, via IRLP and EchoLink. You may reach us on IRLP using node 4754 and on EchoLink at node 4249. If in the area, K7WIN's repeater is on 449.725 MHz, with a -5 MHz offset and 179.9 Hz PL. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Tuning AO-16
by Alan Cresswell 30 Apr '08

30 Apr '08

Bob, Can you hear the AO-16 carrier on the downlink?. It is not strong but still quite noticeable (at least in this part of the world). If you zero beat to the carrier then you are in the right spot to then select either Upper or Lower sideband and you should then resolve the SSB OK. Good luck Alan ZL2BX

Cute 1.7+APDII and SEEDS over West Malaysia
by Sion Chow Q. C. (9W2QC) 30 Apr '08

30 Apr '08

Dear All, Below is the recording of this morning's pass of Cute-1.7+APDII and SEEDS over West Malaysia. Listened out for Delfi-C3 but nothing heard on both frequencies. Time: 1115 Local, 0315 UTC Elevation: 27 degrees Tracking Object-J http://www.9w2qc.net/amsatbb/cuteseeds01may1115.mp3 The first 6 minutes are Cute-1.7+APDII CW telemetry and the remaining of the file is SEEDS telemetry. Looks like it is really time to put another UHF yagi up the rotator for simultaneous RX of Cute-1.7+APDII and SEEDS. :-) Good luck to the teams involved and hope that the telemetry is useful. 73, Sion Chow Q. C., 9W2QC.

As per subject, Delfi-C3 heard in FM05pj tonight. Packets copied! The keps on the mission control page seem to be right on--when the footprint of the bird showed illumination, it came on as expected. 73, Mark L. Hammond [N8MH]
