PSK 31 Apps for smartphones

[Lightspeed]

Hi Scythe,

I thought you'd catch on to this eventually :-)

Re deciphering the signal:

Firstly the signal has to be detected. Its short duration so difficult to catch.

Secondly that signal has to be identified as a PSK 31 data burst. By the time its identified its over

Thirdly, even if the signal is detected, captured and deciphered all that the hostile will have is a series of code letters for example:

r18 5b in 300

This is an approx. 1 second burst of transmission. The decoded plain text still means nothing to a hostile. To the intended recipient it reads

R18 = Checkpoint R18 ( Recipient knows where the checkpoint is so knows direction)

5b = 5 bandits ( raiders)

In = Incoming

300 = ETA at target 300 seconds = 5 minutes.
