[TowerTalk] Computer control antenna switch

[kk9a@arrl.net]

You didn't specify what transceiver you are using or what you are trying to 
switch.  If you have only one antenna per band, or a tribander and some low 
band dipoles you can use a band decoder to switch to the proper antenna. 
Top Ten makes a nice unit - http://www.qth.com/topten/ and with a compatible 
transceiver you won't need a computer for it to operate.  It senses the 
frequency that you have your radio set to and automatically switches to the 
correct antenna.  It should also work with your Ameritron relays if you 
purchase the source driver module.

Hello,

I am Wayne WD4LYV , and after medical problems for 5 years am getting back 
on
the radio. I cannot reach with my arms to control my rotor and need a source
for an antenna switch that can be controlled by my computer logging software
through the parallel port.

I understand the ameritron switch can be but I would need the interface.

I await replys from my fellow amateur operators. You may read about me at
qrz.com under wd4lyv and see how I use my trackball to control my radio.
