AO-51 is operational again
by Gould Smith 05 Sep '08

05 Sep '08

Both the AO-51 repeater and the BB are active again. The software crashed during the start procedure of the PL tone task late Wed night. The command team has reloaded the software and setup the repeater and the BB. We will be coming out with a schedule for September shortly. 73, Gould, WA4SXM

AMSAT Board Meetings
by Frank H. Bauer 05 Sep '08

05 Sep '08

All, Please recognize that all board meetings are open to all. Attend and enjoy!! I have been an AMSAT member since 1981 and have seen the board minutes in the Journal for as long as I can remember. Yes, it does take a few months to get these in the Journal.but that is mainly to ensure accuracy for the members. If you want to get the details of the board meetings, I suggest you either attend the meeting (and hear it in real time) or get the journal. Those that volunteer to transcribe the board minutes from the tapes spend a lot of their personal time in getting the minutes accurate. I thank them for their outstanding support to AMSAT. 73, Frank Bauer, KA3HDO

Presentation @ Prescott AZ, 4 September 2008 - report
by Patrick STODDARD (WD9EWK/VA7EWK) 05 Sep '08

05 Sep '08

Hi! I gave a satellite-related presentation last night for the Yavapai Amateur Radio Club in Prescott, Arizona. The club meeting had a good turnout, about 60 people. Even though AO-51 was not available for a demonstration I hoped to do before the meeting, it was still a good evening for talking about satellites and AMSAT. Thanks to the club for inviting me up there and for the good time last night. Even though I returned to Phoenix much later than I had originally planned, it was fun. And thanks to those who were prepared to work that AO-51 pass during my demonstration. Having some stations standing by for those passes ensures a good show for the audience. Have a good weekend, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Re: sun noise and other natural noise sources
by Michael Heim 04 Sep '08

04 Sep '08

Thank you, Domenico for the information, A lot of reading and study on this is in order. I'm probably different from many microwave ops, as I started high and am working down in frequency, hi. well, sort of, as I was on 1296 before I was on 10 GHz. I used the sun noise calculations that you gave, Domenico, as referred to me by another microwave op (for 10 GHz). Basically he directed me to a website, of which I do not remember, but you were quite correct, I measured 5-6 dB on 10 GHz using my 60 cm offset fed dish. I am still relatively new to 10 GHz, being only active since last summer. Without doing a lot of study, (of which I plan to do anyway, when I get the time to do so), you answered my question, and that is no, I will not see enough of a change in the noise floor (when aimed at the sun) with the antenna gain that I am using to be able to measure, however I should see an increase in the noise floor when aiming at a warm body, ie the earth, or perhaps some object such as a tree, building, etc. Anyway, that's what I was looking for, a way to test what I have using simple means (and my not having a calibrated signal source). I HAVE checked the converters using a signal source at a friend's shack, but the unit with the antenna attached we couldnt, of course make a meaningful measurement. So I know the frequency is correct, not an image, and the LO is calibrated well enough that I shouldnt have any problem finding the bird once it comes online in mode S. So I will consider that if I point from cold sky to earth, if I see a change in background noise, things are probably working.
