Hi Les, N1LS Do you know the EIRP used at 1296 MHz by DJ5AR or by PA3FXB to complete the International Space Station-Bounce on 1296 MHz CW QSO using the ISS as a passive reflector ? Thanks for the information 73" de i8CVS Domenico - Original Message - From: "Les Rayburn" To: "AMSAT Ma

Hi all, does anybody know what kind of rotators are they using? Tracking ISS is quite different from tracking the Moon. Thanks. 73s Fabio IZ5XRC On Tue, May 28, 2013 at 10:13 AM, M5AKA wrote: > --- On Tue, 28/5/13, i8cvs wrote: > > Do you know the EIRP used at 1296 MHz by DJ5AR or by > > PA

WOW ! From my modest EIRP calculation via the handbook that will be about 129130 W (129KW) (some error included...) That's a huge power... 73 El 28/05/13 04:13, M5AKA escribió: --- On Tue, 28/5/13, i8cvs wrote: Do you know the EIRP used at 1296 MHz by DJ5AR or by PA3FXB Hi Domenico, DJ

in power. The EIRP ( Effective Isotropic Radiated Power) is : 200 W x 794.328 = 158865.647 watt = 159 kW (rounded) 73" de i8CVS Domenico - Original Message - From: "Ing. Pavel Milanes Costa" To: Sent: Tuesday, May 28, 2013 3:20 PM Subject: [amsat-bb] Re: Internationa

Hi Domenico and all others, interested in this subject. I am not looking for completing QSOs only and would like to test with receiving stations too. if you have an antenna for 1296 MHz and are able to do ISS tracking, we can try. I can perform the complete doppler compensation as well for

Hi Domenico, Thanks for your interest in the ISS reflections Now about your questions. 1. I started calling Andreas as soon as my dish could see ISS. That was on May 23 at 8 degrees elevation. So the distance would have been close to 2000 km at that time. Andreas reports that he hear
