On reflection I think Loran A was on about 1930.  From what I recall it sounded 
a bit like multiple bandsaws fading in and out with their relative phases 
wobbling around like the efforts of a not very good disco DJ.

Hi John,

Thanks for that info, I don't remember LORAN A on 1900khz the only thing I
recall is the navigational aid somewere around 1900khz which sent a series
of differing frequency tones & was quite melodic but I can't remember what
it was called, unless that was LORAN A & not the chattering type of
transmission we are used to with LORAN C.

I doubt that it could be a Loran line.  The nearest Loran system in

frequency used to be Loran A with a centre frequency just above 1900kHz. It

was the bane of Topband DXers but was shut down years ago.
