Hi Rob that is not noise that is one of the oldest residents of the band=0A=
:-)) It is the Canadian Naval station at Newport Corner nr Halifax Nova Sco=
tia.It is nor unusual for it tobe 30 to 40dB over the noise level. Itis a g=
ood indication of propagation conditions as was the stimulus for the first =
TA attempts on 137kHz.=0AThe 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 u=
sed for submarine comms., but has been very quiet in recent years. =0A=0AAl=
