[Elecraft] K3: Receiving 4th Harmonic of AM Station

[Ken Kopp]

Harmonics from BC stations are not uncommon.
Those of us who haunt 160M are familiar with them.

In your case, the question is how strong they actually
are, and does the station meet it's FCC specified
specs?  Often, the "engineer" ... if the station actually
has one in residence ... probably is unaware of any 
harmonic(s) ... and in reality, doesn't care.

Today, many / most stations have an engineer on 
call for when they need one, and he / she's often 
hundreds of miles away.

I have a 1KW on 570 kHz three miles away and it's 
not a problem.  

Tell us more...
