Presentation--Introduction to Amateur radio?
by Mark L. Hammond 14 Sep '09

14 Sep '09

Hi all, I'm giving 2 talks in the next 2 weeks to two compeletey different audiences. This Thursday will be to the Johnston Amateur Radio Society, and I hope to do a live demonstration during the ~7pm Eastern pass of AO-51! The point of this email, however, is that the following week I am going to talk about our satellites to non-hams. Does anybody have an "Introduction to Amateur Radio" PowerPoint presentation (rather than an "Introduction to Satellites, which we have on our web site)? Thanks in advance for any help...I figure why reinvent the wheel? :) -- Mark L. Hammond [N8MH]

So with all the space on 70cm..... The voice beacon is on the same frequency as AO-51. Is that right ?

I will plan to make two trips to the DM86/87 grid boundary which is the OK-CO state line about 6 miles north of my current QTH in DM86. This will depend on the weather. I plan to be on: 16 Sept on AO-51 for the 23:57 pass 17 Sept on SO-50 for the 00:47 pass 19 Sept on SO-50 for the 00:05 pass 19 Sept on AO-51 for the 00:17 pass I am currently still on most passes from DM86 in Kenton, OK. If you work(ed) me just drop me an email and I'll get a QSL card to you after I return home. 73 - KB9BIT portable DM86 in Oklahoma

Re: AO-51 repeater back in operation
by Mark L. Hammond 14 Sep '09

Hi Andrew, AO-51 is essentially a "next generation" PACSAT. Each craft runs its own OS, which are all similar. Google Harold Price NK6K and you'll find this link: http://www.amsat.org/amsat/sats/nk6k/msatmain.html It gives a few important tidbits so you can see the general picture of satellites, OS, file systems, etc. The size of the upload depends on the satellite; usually there are multiple files, and their sizes vary. In the end, it's something under 1MB in total. Each piece of code adds more functions. So, it's a flying computer with CPU and memory and the OS and applications have to be uploaded and started...not a foreign concept for anybody that has installed an application! Most satellites these days will probably use a the 9600 baud "standard" data rate for uploading. When you only get a few minutes to upload/test just a few times each day, it takes a while to pull the whole thing off using a 9600 baud RF connection. The good news is that Gould is really good at it :) 73, Mark N8MH ___ Re: AO-51 repeater back in operation Subject: [amsat-bb] Re: AO-51 repeater back in operation From: "Andrew Rich" <vk4tec@xxxxxxxxxxxxxxxxx> Date: Mon, 14 Sep 2009 01:22:11 +1000 Could you explain a bit about the software load Operating system How much you have to upload data rates ? ---------------------------------------------------------- Andrew Rich Airways Technical Officer Grade 4 Surveillance - RADAR ADS-B Amateur Radio Callsign VK4TEC email: vk4tec(a)tech-software.net web: www.tech-software.net ----- Original Message ----- From: "Gould Smith" <gouldsmi(a)bellsouth.net> To: <amsat-bb(a)amsat.org> Sent: Monday, September 14, 2009 1:13 AM Subject: [amsat-bb] AO-51 repeater back in operation >I turned on the main AO-51 repeater this morning (145.92/435.300).

WD9EWK from DM34 yesterday
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Sep '09

13 Sep '09

Hi! I made a quick drive up the I-17 freeway yesterday to the Sunset Point rest area, about 50 miles/80km north of Phoenix in grid DM34we. I had intended on trying my hand in the ARRL VHF contest that was in progress, using the all-mode gear I typically use on VO-52. No luck there, but I did work two passes from the rest area (one each, on AO-27 and SO-50) before a thunderstorm prevented me from trying one more SO-50 pass around sunset. I only logged 17 QSOs between those two passes. This spot is close enough to the Phoenix area where I can return to it for future satellite activity on short notice. I think most of you who worked me up there yesterday already have grid DM34 confirmed from my past trips, where I've worked from several different locations in this grid including a couple of grid boundaries (DM34/DM35 and DM34/DM44) in the last couple of years. If you would like to receive a QSL card confirming a QSO from yesterday, please e-mail me directly. If you're in the log, I'll send out a card. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

ic-910 switching help
by andy thomas 13 Sep '09

13 Sep '09

I know this is an old chestnut, but when in satpc32 and with both frequencies set on the iss simplex 145.825, satpc32 shows the up/downlink doppler but switches the 70cm tx subband. How do I configure so that the up and down links can be in the same band? immediate problem is packet on the iss (in between pollux!) I found out it couldn't be done in HRD so i am evaluating satpc32. 73 de andy g0sfj
