[Elecraft] k3-broadcast band reception

[David Yarnes]

Larry and All,

Well, I think you can relax.  My K3 is now receiving at 580, and seems to be 
doing so properly.  It was interesting though.  Several times I had verified 
that all the settings were right, and that the KBPF3 was engaged.  Those 
settings were fine, and I wasn't hearing anything below about 620 khz.  So, 
I tried changing antennas, and in preparation for doing so I disconnected 
everything--power, antenna, etc.  On a different antenna, I could hear my 
local station at 580 khz just fine.  Then when I switched back to the 
original antenna, that worked too.  So, I basically attribute my problem to 
something akin to what computers often require--a complete power down, 
including power disconnect, and then power back up.  That I had not done 
previously since first noting the problem.  Since then I have checked 
several times, and everything is A. O. K. on broadcast band reception.  As 
far as I know, nobody else has had this problem, so I think you are safe to 
assume it's not a concern.
