[RFI] Interfering signal on 40 meter

[Kenneth G. Gordon]

Over the past several weeks, I have been hearing a constant, intermittant signal on a 
frequency very close to 7103 kHz.

It is a steady, repeating carrier, sounding like someone is repeatedly and constantly keying a 
CW transmitter on and off.

I have not yet looked at it with a spectrum analyzer, but I am curious if anyone else here has 
noticed this "thing" and if you might have a clue about where it is coming from,and what, 
exactly it might be?

Once in a while the signal will change characteristics for a short while and sometimes the 
length of the dashes will change slightly, but it always reverts to the relatively short and 
continuous intermittant dash.
