Australian Amateur Radio Station
Various wire antennae are also used
at different stages for experimentation
purposes. I have had very good
success at my previous QTH with Off
Centre Fed Dipoles. Over the years
many types of wire antennae have
been tried and I guess that is a result of
having spent most of my ham radio
time in a big city on an average
Plans are to soon put a multi-band
dipole with open-wire feed line for use
mainly on 160-40 m.
A remote 4-Port antenna switch is used to select between the different antennae from within the comfort of
the "shack". The switch is controlled with a Pic-Axe 08M controller to both select the appropriate antenna
and to display information on an LCD. As different Antennae are changed / replaced, the Pic-Axe is
reprogrammed with appropriate information. A band switch data input available on most modern
transceivers was considered but in practical application it is much easier to change between antennae
based on propogation, not band.

Various transceivers are used at my shack, and most don't last long due to my penchant for trying most rigs
on offer. Over the years I have tried just about all transceivers and will enjoy continuing to do so!
In September 2009 I put the final covers on my completed Pic-A-STaR
Transceiver and have now built 2 versions.
