[Elecraft] K3 APF Increases electric bill

[Steve Ellington]

While tuning across 80m last night, with APF turned on, I heard a VE6 calling CQ. He wasn't very strong and not discernable on the SDR bandscope but his CW was as clear as a bell in the headphones. So I gave him a call and got no response. He called CQ again so I turned off the APF and his signal became totally unreadable in the noise. 
I'm guessing but under these conditions I believe I realized a 10db improvement in SNR. For the VE6 to copy me I would need to run  at least 1,000 watts but even that would likely not be enough because the K3 alone puts me at a transmit disadvantage. 

So I demand a refund for this APF thing....Oh wait....I forgot....It's free. 

Will Elecraft pay my electric bill?
