FO-29 and VO-52

Hi, I would like to know if I'm dreaming, but will it be possible for me to use these two satellites with my pair of FT-817 running on SatPC32?? Am I asking too much for my 5W only radios ?? I'm using 2 Eggbeater antenna from M²... EB-144 and EB432 with AR² preamps on both antennas feed with heliax. 73 -- Jean-François Ménard VA2SS =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= AMSAT www.amsat.org / Member #37102 ARRL www.arrl.org =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

SatPC32 doppler file

Hi, Could somebody send me his doppler file for SatPC32 ?? I'm a newbie, and I would like to figure it out how FO-29 and VO-52 are configured in this file. I actually trying to "calibrate" my setup to use those birds. I'm using 2 FT-817ND with SatPC32. Works great !! 73 -- Jean-François Ménard VA2SS =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= AMSAT www.amsat.org / Member #37102 ARRL www.arrl.org =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Ho yes.... probably easier to solve that way. I got this problem yesterday when editing my doppler file. The problem is your doppler file.... Check if you did not change the ACSII format of the file. Be sure to use colon , and not coma . to seperate each parameter..... an example of a line in my doppler file: AO-51,435300,145920,FM,FM,NOR,0,0,VOICE No coma at all when editing, always colon to separate parameter. Be sure to save in ASCII format. Other mode sometime add unusual control that are not needed and cause the problem. Try this and keep us informed !! 73 Le 3 août 2009 11:54, Jim Heck<jim(a)milnet.uk.net> a écrit : > Hi Jean-Francois, > > No, I see nothing in the freq display - its just blank! > > 73 Jim > >> -----Original Message----- >> From: Jean-François Ménard [mailto:[email protected]] >> Sent: 03 August 2009 13:46 >> To: Jim Heck >> Cc: amsat-bb(a)amsat.org >> Subject: Re: [amsat-bb] SAT PC H e e e lp! >> >> >> Hi, >> >> Do you see the uplink and downlink frequencies displayed properly in >> the upper center of SatPC32 screen when you choose a satellite or you >> do not see nothing ??? >> >> >> 2009/8/3 Jim Heck <jim(a)milnet.uk.net>: >> > Hi Folks, >> > >> > Wonder if anyone can help me?

Frequency 145.800MHz 4 to 5 seconds of silent carrier approx 4 minutes into pass followed by a shorter burst of 1 to 2 seconds. 2 seconds of silent carrier approx 9 minutes into pass. Above timing based on Keps which I believe to be wrong. After predicted LOS a further couple of carrier bursts were heard at approx + 2 minutes with a characteristic sound of an intermittent connection. David G8OQW

Or, another way of comparing the cost of $8000 for 3 weeks operation is: TubeSat $8000 for 21 days = $380 per day AO-51 $100,000 for 1850 days = $54 per day. and if it lasts for another 5 years. $27 per day. What a good deal AO-51 was.

Frequency 145.800MHz 30 seconds of silent carrier at 3 minute interval. Keps are still wrong as default download by PCsat32 & HRD. Signal audible long after predicted LOS. David G8OQW

The space and mass required for the fuel and attitude control system would be prohibitve. CubeSats are better solution for a communications satellite as you get 10 years of 20 minute passes rather than 3 weeks of 10 minute passes. A 3U CubeSat might barely have enough space for an engine, attitude control and fuel but you'd end up with something like Arsene (AO-24). 73, John KD6OZH ----- Original Message ----- From: Joe To: John B.

"And, best of all, the price of the TubeSat kit actually includes the price of a launch into Low-Earth-Orbit on an IOS NEPTUNE 30 launch vehicle. Since the TubeSats are placed into self-decaying orbits 310 kilometers (192 miles) above the Earth's surface, they do not contribute to any long-term build-up of orbital debris. After a few weeks of operation, they will safely re-enter the atmosphere and burn- up. TubeSats are designed to be orbit-friendly. Launches are expected to begin in the fourth quarter of 2010."
