OK, I wasn't sure how wide the ROS signal was but it obviously is quite wide. 
Similar to ALE in bw terms?

I have to say ROS sounds an odd signal - kind of like one of those computers 
from 1970s SCIFI movies! Perhaps the author could put a lot of blinky lights on 
the GUI for that authentic retro feel :) LOL

As to whether it is legal or not I think I agree that as long as the 
transceiver is not jumping around in frequency it isn't a problem. 

Makes you think about the legality of ALE with it's frequency hopping 
properties and soundings? Is ALE really legal under current regs?

Hi Sholto,

I believe ROS is 2250 Hz regardless of baud rate and hence similar BW to 
standard ALE 141A and some Paxtor III signals.
