The one TRUE method is do whatever it takes to make the QSO! In reality I almost always wind up tuning both up and down links. I make sure most of the adjusting is on the higher frequency.
I can't say I have ever slid into another QSO, but even if I do, it is just an opportunity to speak with more friends I haven't met yet! I am usually very hard pressed to find more than one or two QSOs in the passband anyway. As I mentioned before I have found computer tuning to work just fine on the FM birds (no slop involved), but always find myself fighting against the computer aided linear tuning. I tune the station in perfectly and then the computer moves me off frequency. I tune the station in again and the computer moves me off frequency again. I turn the computer tuning off and make the QSO. I would be game for some pointers as I would like to at least claim I have made this work once. 73, Joe kk0sd -----Original Message----- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Alan Sent: Tuesday, June 01, 2010 8:32 AM To: amsat-bb@amsat.org Subject: [amsat-bb] Re: Doppler Tuning Convention Question Folks I've been patiently silent reading this déjà vu annual discussion and I'm getting a brain crap. - comments that tuning the highest frequency is the "One True Method" Yikes! Why is that? So you can leap frog down the pass band and eventually stomp all over a QSO where folks are tuning both TX and RX to maintain a single constant frequency at the satellite? I've read the " Doppler tends to move more quickly near mid-pass than the computer and software routinely seem able to keep up". Mid pass is when the sat is moving most tangentially to you at which point Doppler shift is nil. I've read statements from many taking pride in their lack of use of current technology. I've read that working tight SSB sats is easier than the wide band FM where the satellite is very forgiving of your sloppy tuning. I've read advise to someone using an FT 736r that your shouldn't tune the RX and ignore the use of the NOR/REV feature, again so you can eventually stomp on other QSO's as you slide down the pass band. Have I just been transported into a Bizarro World? 73, Alan VE4YZ EN19kv AMSAT LM 2352 http://www.wincube.ca _______________________________________________ Sent via amsat...@amsat.org.
