Seeking Input - Possible North Dakota operation
by Tim - N3TL 13 Mar '10

13 Mar '10

Hey everyone, I'll be making a quick trip to North Dakota tomorrow (Sunday, March 14), and have the possibility of operating portable from DN96. However, the only satellite pass that I know with certainty that I can work is the 0345-ish UTC Monday (Sunday evening in North America) pass of HO-68, which has a maximum elevation of almost 70 degrees to my location in DN96. Alan Kung has asked that the orbit in question be reserved for packet in his latest schedule - and this is where I'm writing to seek input from the operators who will be in the footprint during this orbit. First and most importantly - does anyone need North Dakota and/or DN96? Second - if there IS interest in FM voice contacts during that particular orbit, will any packet operators reading this please respond with your thoughts about having roughly 10 minutes of voice contacts - maximum - during that orbit? I am not checking luggage, so will be carrying only my HT and a whip antenna. Given HO-68's outstanding performance and the path of this pass, I believe I should be able to work the satellite consistently on that handheld station from roughly 0345 UTC to 0355 UTC. I will be happy to activate North Dakota and DN96 if there is interest, and if the packet operators who plan to use HO-68 are OK with this 10-minute window of FM voice operation on Sunday evening. I'll also be happy to avoid the pass if there are major concerns. There is one AO-51 pass, during the 1300 UTC hour on Monday morning, that I may be able to work - but I'm not confident that will be the case. I expect to be in meetings by then, which makes the HO-68 pass in question the only one I am certain I'll be able to work. Please post any input to the BB so that everyone can see any feedback I get. Thanks in advance for your time and thoughts. 73 to all, Tim - N3TL Athens, Ga. - EM84ha

Alan, Thank you very much for your great work with HO-68 and for your effort to solve the voice/packet problem. I do not entirely follow the schedule, however. Does "Digital Transponder" mean packet? Where it says: > 14 Mar. 2010, Digital Transponder > ================================ > 16:45...Turn On--Linear Transponder > India, Africa, Middle East, > Europe,NA > 17:30...Turn Off does that mean digital (packet) or linear (SSB)? Does it mean that the linear transponder will be active on 14 March and 15 March and that the rest of thw week is digital only? Please clarify if possible. 73, Bill NZ5N > Message: 14 > Date: Sat, 13 Mar 2010 00:07:41 +0800 > From: "Alan Kung" <alankung(a)public3.bta.net.cn> > Subject: [amsat-bb] HO-68 Schedule - 14-21 Mar 2010 > To: <amsat-bb(a)amsat.org> > Message-ID: > <009201cac1fe$35fc6db0$6c01a8c0@ba1duoffice> > Content-Type: text/plain; > charset="gb2312" > > Hello all, > > I got a lot of responses about problem of digital mode > through HO-68.

John, are they on echo main reptr or on the qrp repeater? We didn't hear them on last nights echo pass at 1700hrs est...

He reported that their preamps and antennas are working now and they have plenty of transmit power to be heard. Thanks to those who provided wiring info for their preamps. They are definitely hearing better. Many stations were worked on this pass. 73, John K8YSE _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Antenna setup
by Jacob Tennant 12 Mar '10

12 Mar '10

Hello everyone, I have a antenna setup question as I am new to satellite operations so please bear with me... I have a 2meter beam and a 70cm beam from my former adventures into VHF weak signal operations and was wondering about using them for satellite work. Was thinking that since I don't have a az/el rotator yet, if I set them up on a single cross-boom with the TV rotator I have now, angle them with the elements at 45 degree angles and the booms angled 30 to 40 degrees front end up I might be able to get some decent ability into the FM satellites (AO51, SO50, AO27, ISS). I already have the good coax for them (LMR-400) and a duplexor for my FT-857D. Was going to try to install the antennas on top of my storage building with a height of approx. 16 feet. That's the highest structure I can get onto that belongs to me. Any alternate ideas or advice is always welcome as I said before this is all new to me. Jacob Tennant - K8JWT Morgantown,WV FM09ap

Hi Jacob, >From my point of view and short time experience, The description of your proposed set up would yield favorable results. I am using an 11 element 2m yagi and a 432 16 element both mounted vertically (with az/el). most of my worked passes are in the 10 to 35 degree range and the signals are fairly good and readable most of the time. Working the Birds without optimum conditions is still a ton of fun. 73 LOUIS, KD5GM CW, The original digital mode Message: 7 Date: Thu, 11 Mar 2010 20:32:20 -0500 From: "Jacob Tennant" <k8jwt(a)comcast.net> Subject: [amsat-bb] Antenna setup To: "Amsat BB" <AMSAT-BB(a)amsat.org> Message-ID: <000001cac183$dbfd2f40$93f78dc0$@net> Content-Type: text/plain; charset="us-ascii" Hello everyone, I have a antenna setup question as I am new to satellite operations so please bear with me...

Hey everyone, On the 2130-ish UTC pass of AO-51, Mark, N8MH, was QRV from K4T and said he plans to work CW during the pass of FO-29 That he should get AOS for at roughly 2348 UTC. The satellite will be moving southwest from Europe. 73, Tim - N3TL

Here's an audio recording of the AO-27 pass on 12 March 2010 at 1957z. Great signals from K4T and he managed to work it all the way down to his horizon at the end of the 7 minute repeater portion of the pass. http://www.papays.com/AO-27_12Mar2010_195733z.mp3 73, John K8YSE
