The North American Pass of SO-67 on 27Dec2009
at 1443z is now on my webserver. The bird was
strong as usual. It is difficult not to respond
immediately to a call to your station, but those
that wait for the "tail timer" to expire, will have
more than 3 seconds to exchange their information.
Watch the S meter and wait for the tail to expire
before you transmit. This doesn't always work if
there are others still transmitting after the tail
timer expires. Their signal is not repeated but it
prevents the repeater from re-transmitting your signal.
Full duplex allows you to hear the bird when you are
transmitting and makes successful qso's much easier.
Thanks to AMSAT-South Africa for this very strong bird.
If the tail timer can be re-configured, contacts using
a handheld and a rubber duck antenna will be possible.
Right now there is just too much confusion due to everyone
transmitting at the same time. Full duplex really helps.
