[RTTY] The Case for QYF (was We Need a New Strategy)

[Richard Schumann]

Say, don't RTTY sigs have a 'fingerprint' just like the human hand?  I mean, can't one set up some software to detect characteristics unique to the transmitter and 'style' of sending of the jammer?  

That way, when the jammer has had his fun for the day, he may go on to have a 'normal' qso with someone using his real ham call and be identified.  Would make a great episode of Sherlock Holmes...

Hey Chen....that sounds like another feature you could  add to the already myriad ones in your cocoaModem...ha ha!

:-P

Richard kn7fsz, who's opinion is not even worth 1 1/2 cents....

  If that is true, the scheme of the DX coming to your frequency will not work either.

  A sociopath would just go up the band giving a bogus 599 to every station that he hears.  

  RTTY is especially easy to fake, since it neither involves a "fist" nor a voice -- just make up a macro that gives an identical exchange as the DX.  The only way to know is to measure the precise baud rate and the duration the RTTY signal stays on Mark at the start and end of transmission.  And those parameters can also be easily faked by someone who knows what he is doing.  

  On top of that, a sociopath with a skimmer can easily find where the DX is answering and go QRM that frequency (even with automated software).  

  The sociopaths who I have met are actually quite smart.  Perhaps ham sociopaths are not as bright; I don't know.
