Digital transmissions: Frequency indications mostly center frequency; otherwise indicated
ALE MIL 188-141A = is usually USB VFO!
BC = Broadcast // BD = Baud, or also Burst duration // BRI = Burst repetition interval // SH = Shift or Spacing (Hz)
BW = Bandwidth // OTHR = over the horizon radar // FMCW = frequency modulated continuous wave //
FMOP = frequency modulated on pulse // sps = sweeps per second // vd = various dates // vt = various times

Überhorizont Radar (OTHR) - Bezeichnung "Konteyner 29B6"
Screenshots mit Perseus SDR
Mode: FMOP (Frequency Modulation On Pulse)
Parameter: 50 sweeps/s
Bandbreite: ca. ≤ 13 kHz
Sonagram
(Span 50kHz)
Spectrum Analyse
Auffällig sind die gegenüber
anderen OTHR relativ flach
abfallenden Flanken.
Es werden denn auch nahezu
25-30kHz beeinträchtigt.
Sweeprate direkt mit Perseus
50Hz (Span 0.4kHz)
Sweeprate mit W-Code
20'000μs = 50Hz
a) mit Oscilloscope (20'000μs)
