  CW = Continuous wave
  CS = Call Sign in Morse Code (OK0EU) or 6 sec. gap
  ST = Status in Morse Code sent in sequence from each transmitter

  Status composition is XY where:
 
  X = Transmitter sing letter (H,U,M,D,R)
  Y = Status of the transmitter where:

  I = All parameters OK
  A or R = Bad antenna (SWR>2)
  S = GPS synchronization error	 
  N = Low output power (P<0.8W)
  M = more errors (N+A)
  W = more errors (N+A+S)
  D = more errors (N+S)

  Transmitter location and frequency
  
  H Trebon (JN78JX) 3 594.508 kHz
  U Pruhonice (JN79GX) 3 594.504 kHz
  M Panska Ves (JO70GM) 3 594.500 kHz
  D Dlouha Louka (JO60TP) 3 594.496 kHz
  R Vackov (JO60EF) 3 594.492 kHz

  Status is sent with +40Hz offset

  The same schema as for 3595kHz is used for beacon net on frequency 4649kHz only with different call sign: 
  H OKTR Trebon (JN78JX) 4 649.508 kHz
  U OKPR Pruhonice (JN79GX) 4 649.504 kHz
  M OKPV Panska Ves (JO70GM) 4 649.500 kHz
