Having been monitoring NAVTEX/HYDROPAC broadcasts for many years am now disappointed since the signal seems to be blocked here in Burra South Australia.
Below is the schedule:
NRV GMDSS FEC BROADCAST
FREQUENCIES: 12579.0 KHZ
16806.5 KHZ
22376.0 KHZ
TIMES:
HYDROPAC BCST: 0230 AND 0900 UTC
WX BCST: 0500, 1500, 1900, AND 2315 UTC
NOTE: CARRIER OR DIAL FREQUENCY IS LOCATED 1700 HZ BELOW THE ASSIGNED
FREQUENCY (-1.7 KHZ).
This wideband interfering signal has been present since the 22nd of November on all 3 frequencies, I have 2 radios and am able to reduce the bandwidth to 400Hz with no success.
I have checked with a portable radio and the interfering signal is not local so that rules out RFI.
Has anyone else noticed this? does anyone have any idea where it is emanating from?
Any advise/help is appreciated.
