   hi,,,,i believe it is a form of bell 202t modem signaling  1200/2200 Hz

    http://www.tapr.org/tapr/html/Fax25.html   english

   http://www.futesta.de/theorie/ax25linklayer.html   deutsche

   it seems that 1200/2200 is for VHF+  ,,not sure.

    hope this helps,,,,,,,,,,,have fun + take care.
