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
