Hi all, I'm interested in schedules for QSOs with South American stations on HO-68. Evening hours and SSB QSOs are preferred. I'm in EL88pg and have a decent horizon to the south. I'm especially looking for QSOs with the Central and Southern SA countries. Please reply direct to ko4ma(a)amsat.org, and forward to any interested parties or lists. 73, Drew KO4MA

uplink & downlink mode question
by Jean-François Ménard 30 Dec '09

30 Dec '09

Hi, I', relatively new to sats and I'm still a bit confused about one topic and I would like to make this very clear in my mind.... It is regarding "uplink and downlink" mode configured for each satellite. Ok for FM, SSB and so on.... But... => What about NORMAL or REVERSE doppler shift ?? => When using SSB on transponder, what about when to use USB on uplink and LSB on downlink ?? => When using SSB on transponder, what about when to use LSB on uplink and USB on downlink ?? I'm very confused if my doppler.sqf file is properly configured and a short explanation would be really appreciated. I know this is a basic and fundamental question, but I really need to free my mind with this one. Thank for your patience guys ! 73 and Happy New Year 2010 !!! I wish you health, health, health and more sats to come !!! -- Jean-François Ménard VA2SS =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= AMSAT www.amsat.org / Member #37102 ARRL www.arrl.org =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

I am struggling to keep control of NOVA and the sats I want to chase. Some keps are missing, and there is alot of other general rubbish in the list of sats. What is the best way to create a list of "HAM SATS" I can manage ? Andrew VK4TEC

435.494 MHz CW
by Andrew Rich 30 Dec '09

30 Dec '09

I was hunting for OH-68 (XW-1) And I came across some CW on 435.494 MHz I can't seem to marry it up with another bird. It did not have the "TTT" like XW-1 had. Andrew VK4TEC

HRD doppler tracking
by G0MRF＠aol.com 30 Dec '09

30 Dec '09

Hi all. Can anyone out there using HRD help me with this one? The software tracks in very small increments which sounds really impressive. But can it deal with doppler tracking at higher frequencies? For example, can it handle accurate tracking at S band from low Earth orbit and could it extend that capability to 5.8 GHz? Just trying to figure out the limits. HNY David G0MRF

Heard you on the 08:50 pass, Graham. You were quite loud and clear at the beginning of the pass but audio got progressively weaker as the elevation increased. By about 40 degrees (at my location) the downlink signal was extremely strong but I could not get in and no one else was heard, just a lot of snap, crackle and popping noises. Alex / VK5ALX
