PCALE dev, Charles Brain G4GUO, says:
"Some years ago I started on the development of an ALE
system for the P.C. This started as a training exercise in
DSP and grew from there. I have been amazed at the massive
amount of interest this software has generated from all
around the world."
"Since writing the above I have now restarted work on this
because I am using it to provide a backup orderwire for my
digital voice experiments. The software has become quite
popular in the Utility listening community. I am gradually
adding new radios but this has to take second place to my
more commercial work."
"I have recently entirely re-written all the signal

"Warning, I will not accept responsibility for any damage to
your equipment through use of this software. When using this
software use an Automatic Antenna Tuner and run the
transmitter well below rated output. It is advisable to go
through a tune sequence on
each of the operating frequencies before handing control of
your radio to the computer.
You have been warned."
