[Elecraft] P3 Broad Birdie & straw men...

[David Gilbert]

I don't have a P3 so can't comment there, but I do own a K3 and spent a 
lot of time trying to eliminate birdies when I first got it (before the 
arrival of the excellent SIG RMV software feature).  The second receiver 
is MUCH better shielded than the first receiver and has virtually zero 
birdies of its own, but in my opinion the second receiver contributes 
greatly to the birdies that occur in the first receiver.  In general 
(but not always), I found it important to keep cables away from the 
shield of the second receiver to minimize the birdies in the first 
receiver.

Several other K3 owners who only have the first receiver have made the 
same comment that you just did, so I'm not surprised to hear it again.  
And of course, if you listen for the birdies while having an antenna 
connected to the antenna port, band noise will mask many of them.
