NO Morse training. If they USE Morse at all, it would likely be sent and received by machine as very high-speed bursts to send relatively short messages that would be "low probability of detection" and very difficult to DF because the bursts would be so short. (I don't know that they use this any more ... it was available, but uncommon, back in 1990 when I left Rockwell-Collins Defense Communications for the commercial sector. It's probably been supplanted by FSK, since at equal symbol rates that has about a 9 dB weak signal advantage over OOK Morse and it's actually simpler to encode and decode in hardware/software. I doubt that any of the radio comms the special forces use are capable of Morse code. |
