Attention old timers: anyone solve the 16-bit compatibility problem? I like this program for the Mutual Visibility feature and would like to have it available in my laptop. 73, Jerry, K5OE

JAXA announced launch of two H-II rocket. They are carrying amateur satellites. H-IIA #21 Launch date: 1639-1642z 17 May, 2012 Payload: GCOM-W1 (Global Changing Observation Mission 1st - Water) or SHIZUKU KOMPSat3 (Korean Multi-purpose Satellite 3) SDS4 (Small Demonstration Satellite 4) HORYU2 HORYU2 is amateur satellite. Please reffer the following web site. http://kitsat.ele.kyutech.ac.jp/index_e_new.html H-IIB #3 Launch date: 0218z 21 July, 2012 Palyoad: HTV3 (H-2 Transfer Vehicle) or KOUNOTORI3 HTV3 delivers J-SSOD (JEM-Small Satellite Orbital Deployer) to ISS. J-SSOD is new small satellite deployment system from ISS usig JEM robot arm. Satellites RAIKO, WE WISH, FITSAT1, F-1 and TechEdSat, which are deployed by J-SSOD, also deliver. All the satellites carrying amateur radio system. Deployment will be done Sep, 2012.

Hamfest-NJ
by Dee 23 Mar '12

23 Mar '12

Hi All, I will be at the SPLIT-ROCK Ham fest in Succasunna, NJ tomorrow. 3/24/2012 If you have questions about AMSAT, and or satellite operations, please stop by the table and Get up to date information. I will be demonstrating SATPC32 Software that controls your equipment and gives you doppler corrections To your operating rig. (no live demo's as I'll be indoors) Support AMSAT and see a "model" of FOX1. See you there. Dee Interdonato, NB2F AMSAT NJ Co-ordinator

KISS FM
by Rsoifer＠aol.com 23 Mar '12

23 Mar '12

On an AO-27 pass this afternoon, I worked three stations: N7GWB, WC7V and N5UXT. Nothing unusual about that, but I should mention that I was using a garden-variety FM radio, an FT-7800, and my KISS antenna, a 19-inch dual-band magmount. One more easy way to get on the birds. For more info, please go to the Green Valley ARC Web site, gvarc.us, click on Technical Page, and scroll to my article, "KISS FM." 73 Ray W2RS

USA East Coast Balloon Launch Friday 3/23
by JoAnne Maenpaa 23 Mar '12

23 Mar '12

Hello Everyone, Here is one news item which is more timely at the moment rather than waiting for the weekend ANS news cycle. (We'll post a reminder in the ANS). Interested stations on the USA East Coast may wish to follow this flight on VHF. The HF beacon may likely be heard with wider coverage: + The Project Blue Horizon 6 high-altitude transatlantic balloon flight is planned to launch on Friday, March 23 at 2300 EST (UTC-4) from Owego, NY transmitting on 7.1023 and 10.1466 MHz CW with the N2XE call sign and 144.390 MHz FM APRS using the KD2AUD call sign. Please send reports via e-mail to pbh18.data(a)gmail.com or manually enter received data points at http://www.projectbluehorizon.com/ More information is available on their web page. -- 73 de JoAnne K9JKM k9jkm(a)amsat.org Editor, AMSAT News Service

SatPC32 - New Program Feature - Doppler
by John Papay 23 Mar '12

23 Mar '12

Erich DK1TB has again implemented another great feature into SatPC32 V12.8b by means of a "patch" file. You can find it in the "downloads" link on his website, www.dk1tb.de Scroll down to Section 7, Patches. I often hear others talk about meeting someone, usually a long distance new grid square, on a certain frequency. Since doppler is always in play, telling someone you will be on 435.845 is meaningless unless you are both in the approximate same location. If the other station is at LOS and you are at AOS, your dial readings could be 15Khz apart. It's a great way to miss a 60 second window. The trick here is to use the same point of reference. That reference would be the frequency you are on at the satellite receiver. The whole idea of doppler correction is to be at a constant frequency within the satellite receiver passband. To do that you have to adjust your uplink frequency constantly. And you have to adjust your downlink frequency to continue to hear yourself or someone else using full doppler correction. Erich has now added the option of seeing the frequency you are on at the satellite receiver. This is a common frame of reference so if you tell someone you'll be on 435.845 at the satellite, they can be on that same frequency even though your terrestrial dial frequencies will be much different. Just adjust your receiver or use the up/down buttons in SatPC32 to set your frequency shown in the "Sat" window. That frequency will remain constant as your uplink and downlink are controlled by SatPC32. If you haven't managed to interface your radio with SatPC32, this is just another reason to do so. Staying at a constant frequency at the satellite allows many stations to share the bird without drifting into each other. And being able to know exactly where you are in the passband without doing the calculation in your head gives you more time to concentrate on making a successful QSO! Rumor has it that even a certain Maritime Mobile will soon be controlling his radio with SatPC32. 73, John K8YSE
