Re: LF: Broad signal (noise?) on 137.000KHz

[ALAN MELIA <alan.melia@btinternet.com>]

Hi Rob that is not noise that is one of the oldest residents of the band
:-)) It is the Canadian Naval station at Newport Corner nr Halifax Nova 
Scotia.It is nor unusual for it tobe 30 to 40dB over the noise level. Itis a 
good indication of propagation conditions as was the stimulus for the first TA 
attempts on 137kHz.
The station is transmitting at about 40kW ERP from a new but barely used Harris 
TX the modulation is most likely GMSK and it is capable of multichannel 
independent sideband operaton. It generally is used for submarine comms., but 
has been very quiet in recent years.
