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?

No, I belive that you and others should just demand a free KPA-500 to make up for this amazing APF enhancement.

APF is actually a stealth marketing tool for the KPA-500.  Now you just
gotta' have it.. ;-)

I just knew Eric had something sneaky planned for that new APF feature.  After having sold my K2 a couple years ago to help pay for some unforseen medical bills not covered by my wife's insurance, I've been steadily building my K3 fund and I'm almost to the point where I'll be able to order a 100 Watt K3 complete with most of the accessories.  I may actually have it by Christmas.  The P3 may have to wait a bit, but, that's on the list too.  Been a long time coming.  I have a fellow ham that lives less than a quarter mile from me that's a CW contester as well as I am and he insists on running his new Alpha amplifier flat out in just about every contest.  Right now, my rig is an IC-7000 and I cannot operate the same band he's on without being overloaded, especially 160 meters.  I'm really looking forward to getting the K3 so I can at least have a chance at keeping him at bay.  

Been lurking here since then

Eric - I'd really like one, but:
1. my antenna is only about 15-20 ft from my head
2. my antenna is only 4 ft from a stucco wall full of wire mesh, with a 5:1 SWR at best

I think I'm gonna pass, unfortunately...
