[Boatanchors] LORAN A Revisited

[Drew P.]

Hi All,

A while back there was a thread in this forum starting with GPS interference from LightSquared, progressing to LORAN A, and culminating in wistful recollections of the sound of LORAN A as heard in a radio receiver.  As we know, the LORAN A system in the US went dark over 30 years ago.  One forum participant expressed a wish that he had a recording of LORAN A so heard. 

I have found an audio clip of a simulation of the sound of LORAN-A. It has the "flanging" characteristic of a channel having 2 stations of differing pulse repetition rates.  Even though the timbre is a little off (probably from ringing in the IFT's of the various tube radios I used back in the day) from the way I remember it, it is still quite good. Here it is for your edification and enjoyment.
