Hi,I have a Kenwood TS2000.I can hear stations on the SSB sats but can seem to find my downlink.It is a vertical but I have worked half duplex and by chance made 3 contacts with a decent signal.Now I can find it to easily.Any suggestions??Rich73 [email protected]
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.
