Mikrotik router audio alignment script.

This helpful script was given to me.  It was sent to me by WISP-Router (http://www.wisp-router.com/).  Casey told me it was sent to them by one of their customers.  It will create a beep that changes frequency as the alignment gets better/worse.  Requires (of course) a MT router with a speaker onboard.

    I made a few modifications to this for my use. I tried to document more of it, and make it more configurable. Hopefully this is helpful to someone:

    
# 10 sec delay required by ROS3 for startup scripts?
:delay 10

# set the interface you want to monitor
:local interface "wlan1";

#set the sound frequency you want to use (in Hz)
:local beepfreq "523.251";


#set the number of iterations - approx 1-2 seconds per iteration
:local iterations "150";

:local beep "10ms";
:local no "2400ms";
:local s90 "1290ms";
:local s85 "790ms";
:local s80 "590ms";
