AO-51 in L/S, one orbit mode change Monday night
by Gould Smith 10 Sep '07

10 Sep '07

AO-51 was switched to L/S mode this evening. Due to a scheduling problem, AO-51 will return to 'normal' V/U analog & V/U digital mode Monday night for one orbit Monday night east coast, Tuesday UTC during the 0006Z pass I will activate V/U & V/U mode. AO-51 will return to L/S on the next pass at 0144Z. 73, Gould, WA4SXM AO-51 Command Station

Japanese satellite crashes, Russia suspends launches
by Trevor 09 Sep '07

09 Sep '07

An unfortunate incident that illustrates the hazards of the Space business and why, if it can be afforded in terms of personel and money, it could be best to build two copies of any satellite so at least the replacement can be launched fairly quickly.

distributors of solid fiberglass crossbooms / rods
by Larry 09 Sep '07

09 Sep '07

Good day all! I want to purchase another crossboom, but can't remember where I got my first one from. All I can remember from 3 years ago was that I bought a 6' solid 1-1/2" O.D. piece from a business and paid roughly $68.00 for it. Anyone have an idea where I can get another one from? I'm actually looking for 1-1/2"O.D. 8' to 10' long (running out of real estate up there). Thanks in advance.... Larry

Ft-847
by Don Blachura 09 Sep '07

09 Sep '07

This is a little off subject . Need a little help..... Have been using a FT847 in PSK31 through a Rigblaster plus. The rig Transmits in CW with the paddles and the internal keyer. Also works CW The same without the keyer. When running USB PSK31 through the Rigblaster the rig works without any problems. Taking the PSK31 cabling Off the rig and reattaching the microphone, a MH31 hand mike, I get Nothing out of the rig. I rechecked all menu settings. I rehooked the Rigblaster back up to the FT847 and hooked the MH31 mike to the Ribblaster mike port. In this configuration the radio transmits in Sideband with no problems. On the FT847 Rig will not QSY with the buttons in the MH31 when it is hooked Directly to the FT847 but will function when it is plugged into the Rigblaster. Anybody have any thoughts on this, or prior experience? I Also tested the rig with another MH31 that works well on a FT1000D. Same negative results on the FT847. I also tried using an MD-100 desk Mic that works with the same FT1000D and tried that on the FT847 with Negative results. I hate to tear into this rig without having some Ideas as to what is going on. HELP. Don...w2xb

Re: AO-07 orbit 50159
by John Hackett 08 Sep '07

08 Sep '07

Allen, A pleasure to 'meet' you and have the opportunity to thank you for confirming mode-B for AO-7's orbit 50159. Very much appreciated Allen. I'm currently discussing the relays used 31 years ago, with the chief design engineer, J King ... (which are 'latching' and which are not) ... since, as I'm sure you're aware, this, together with the illumination could also play a part in the mode on/off/on/off sequence. Last year, when I first 'tagged' the 24 hour timer the satellite was in constant illumination ... this time, it's a little more 'debatable' ... (different software packages) ... hence this year's musings re: the mode and when it changes. Last year I established it to be it on or around 08:30 drifting to 09:00. At present, it appears to be 01:45 to 02:00 ... which in itself is rather interesting. I hope you don't mind me CC'ing this mail to Joe K3SZH, Mak SV1BSX and a few other interested parties. I'll do my best to keep the log up to date Allen. Thank you again for your response. 73 John. <la2qaa(a)amsat6.org> .................................................................................... > Date: Sat, 8 Sep 2007 09:51:23 -0500 > To: la2qaa(a)amsat.org > From: afmattis(a)hal-pc.org > Subject: AO-07 orbit 50159 > > < It would be interesting if you could confirm which mode AO-7 was in at > 01:28 on orbit 51059 Allen. > > John: > > AO-07 was in Mode B.

Skes on AO-07 mode B.
by LU2DPW Juan Cralos 07 Sep '07

07 Sep '07

Hi Sat Fans!! I'm very interesting sked with Central America, Caribean and South Florida stations for possible DX contact on AO-07 Mode B at night passes. Last days ago I worked station WP4CNU form Puerto Rico in good conditions. I work with minimal elements: FT-726R with 10 W input and my antennas are: a Quad Swiss for VHF and Vertical Diamond X-200 for UHF. Please contact with my e-mail address: lu2dpw(a)hotmail.com Many thanks and see you on this excelent bird!! 73 all Juan LU2DPW GF05gi --------------------------------- Los referentes más importantes en compra/venta de autos se juntaron: Demotores y Yahoo!.Ahora comprar o vender tu auto es más fácil.

Baa ba little lamb.
by John Hackett 07 Sep '07

07 Sep '07

So much for the (convenient) 24 hours timer theory proffered in response to my previous mails regarding the timing of AO-7. This is the 3rd consequtive day the 24 hour timer is *NOT* playing ball. 05/06 Septembert 2007. TIME. ORBIT. MODE. 23:46 50133 B 23:51 50133 A 01:35 50135 A 01:36 50134 B 01:44 40135 A I have received confirmation mails from AJ9K and K3SZH that their log entries *ARE* correct. As you Gentlemen on that side of the pond are wont to say ... "go figure!". Incidentally, the mode changes spell "baa ba" ... it couldn't be that AO-t thinks we're a veritable bunch (flock) of sheep?. Just a thought. 73 John. <la2qaa(a)amsat.org>

To whom it may concern, Any lack of response to e-mails from LA2QAA after the 10th of September has absolutely nothing to do with impoliteness and everything to do with major surgery. It's the pig's heart again. OK Terry, (G1WPR) ... just for you, here it is again ... How does a pig feel when it loses it's voice ?. Dis 'grunt' led !!!. 73 John. <la2qaa(a)amsat.org>
