[Skimmertalk] RTTYserv and Russian beacon

[Larry - K1UO]

I guess my question really is “Are these Beacons actually calling CQ or something that matches the RTTY Skimmer reporting criteria?”

It is somewhat more complicated in RTTY SkimServ.  There is a second .ini file that contains expected CQ patterns and their relative probability, both for normal operation and for specific contests.  I presume that RTTY SkimServ is more skeptical if it copies a low-probability pattern - that is, it requires more repetitions or other confirmatory information before identifying that transmission as a CQ.

  Is there a CQ  or TEST qualifier also in RTTY Mode that needs to be met within the RTTY Skimmer software before the callsign is reported?

  Thnak you Pete and Wes 
  Well,It's interesting phenomenon that RTTYSkimmer decodes 
  morse code as callsign. 

  Here I notice again JA's new band plan from Apr.2015 
  http://www.jarl.org/English/6_Band_Plan/JapaneseAmateurBandplans20150105.pdf 
  Unfortunately,80m's complex hashed band will never be solved. 
  There are for JA's air forces 

  Best wishes

    Hi Dai - and thank you for a thought-provoking report.  It's interesting 
    to me that these beacons are being decoded by RTTY Skimserv - I wonder 
    what is causing that.  I had understood that stations in ITU Region 2 
    were not using RTTY on 40M below 7040.  If that is correct, then maybe a 
    solution for this would be to set a 40M RTTY segment's lower limit at no 
    lower than 7040 unless you wanted to see thise beacons.  This is just a 
    first thought.
