Thanks for the answer to my question. SatPC32 with WinListen is exactly what I was looking for. The more I use SatPC32 the more I appreciate the effort that went into it and how well it works. 73 W9KE tom ...

WinListen, as part of SatPC32, will do the same. Choose the Window for two observers option. It's a great feature for any program, and one I've used often to find good windows to EU and mid-South America. 73, Drew KO4MA -----Original Message----- >From: Thomas Doyle <tomdoyle1948(a)gmail.com> >Sent: Oct 12, 2011 11:06 AM >To: AMSAT-BB(a)amsat.org >Subject: [amsat-bb] Can you work DK1TB on a satellite ? > >A friend who knows a little about ham radio asked me me about satellites.

Can you work DK1TB on a satellite ?
by Thomas Doyle 12 Oct '11

12 Oct '11

A friend who knows a little about ham radio asked me me about satellites. He asked a couple simple questions.- Can you work Alaska on the satellite ? When I answered probably. He said great - lets try it. I explained a little about orbits and then he said. Ok - so if you know you can work Alaska how do you know when you should try. Alaska is not all that far from my QTH here in Packer Country so for my example I have changed the question to "Can you work DK1TB on a satellite and if so which satellite and when is it possible ?". We all know many ways to answer this simple question. Here is the easiest way I know. If you have an easier way please let me know. http://www.tomdoyle.org/canIworkDK1TB 73 W9KE tom ...

Yes, Harvey, SRMVU inclination of 20 degrees is correct. As the satellite launched along with the Megha-Tropiques satellite, which is going to monitor the precipitation between the tropics, the inclination is 20 degrees. 73 KC2YQJ Dinesh Cyanam On Oct 12, 2011, at 10:52 AM, H.

Satellite Beacon Tracking Request
by Mani VU2WMY 12 Oct '11

12 Oct '11

Dear friends, As you all might be aware that two cubesats 'Jugnu' and 'SRMSat' using amateur frequencies are to be launched by PSLV C-18 from Satish Dhawan Space Centre [SDSC], Shriharikota, India. The expected launch time is 05:30 UT. In this regard, I'm herewith forwarding the mail from Mr. Shantanu Agarwal, Team Lead for the 'Jugnu', requesting the Global Amateur Radio fraternity to provide the CW Beacon signal Report along with the plain decoded morse message, if possible. Any help in this regard would be greatly appreciated, as this would be very helpful to evaluate various ob-board system performance. 'Jugnu' beacon is at 437.275 MHz, OOK. The reports can be sent to the following mail ID.s wmy(a)isac.gov.in[1] shantag(a)iitk.ac.in[2] The predicted TLE's: JNU 1 99999U 11072A 11285.24724444 .00001785 00000-0 96625-3 0 1235 2 99999 20.0506 66.7109 0018405 5.1080 190.7439 14.11338922 19 SRM 1 88888U 11072A 11278.34967500 .00001077 00000-0 60876-3 0 1233 2 88888 20.0603 97.4017 0010015 338.6461 208.4324 14.09199968 14 Thanks in advance and looking forward to your valuable reports. 73 de Mani, VU2WMY Secretary & Station-In-Charge Upagrah Amateur Radio Club VU2URC ISRO Satellite Centre HAL Airport Road, Bangalore-560 017.

CW telemetry from 'Jugnu'
by Mani VU2WMY 12 Oct '11

12 Oct '11

Dear friends, On behalf of the 'Jugnu Team' from the Indian Institute of Technology-Kanpur, India, I thank all the Amateur radio Stations that responded to our request in sending the beacon signal reports. Our sincere thanks to OM.Shamai 4Z1WS from Israel. His report from Israel was the 'First' indication for us about the beacon 'ON' status.The decoded CW text message by Shamai 4Z1WS indicated the nominal performance of the spacecraft. Subsequently, the beacon was heard by me, Nittin VU3TYG and Guru VU2GUR all from Bangalore. Our sincere thanks to OM.Christian F1AFZ from France. We look forward for more 'Critical' signal reports across the Globe in the coming days. 73 de Mani, VU2WMY Secretary & Station-In-Charge Upagrah Amateur Radio Club VU2URC ISRO Satellite Centre HAL Airport Road, Bangalore-560 017.
