[amsat-bb] SSB sats

[Burns Fisher]

I'm a bit confused about what you have done, although I think I know what
you are trying to do.

What I get from your mail is that you have a TS2K (running in satellite
mode?  I.e. full duplex?  Using computer tuning?) and you are trying to
hear your own signal on the downlink.  You have a vertical antenna (two?
One for each band?  Remember the TS2000 has a separate connector for each
band.)

Of course a vertical is not as good as a yagi with a rotator, but I know
people who have made lots of contacts with a vertical on their car.

Both SatPC32 and MacDoppler have the capability to tune only the receive
(or the tx) side, so the technique is to whistle or click or say something
distinctive transmitting while tuning the Rx to find your signal.  Then
lock it together with the Tx (I think that only happens on MacDoppler) and
you should be good for a while all across the passband.  Things do change a
bit with temperature etc, so you may have to do this each pass.  Don't
start out on AO-7...try one of the XW birds.  AO-7 is a bit tricky--some
parts of the passband sound better than others; the XWs work great.

Is this what you are asking?  My apologies if I'm just blathering on about
something you already know.
