[Elecraft] K4 question +12m SOLVED

[eric norris]

I am surrounded by hams in my suburban neighborhood, one new ham two blocks away who is S9+20db when he runs qrp.  I pray he doesn't learn cw.
My question is, what model of K4 will supply the same blocking dynamic range equal to or better than the K3S?  The K4HD?  I need RF protection!  Every day is Field Day here.
On another topic, I took the advice of someone on this list who suggested my best solution to my 12m antenna problem was to throw up a low dipole with bubble gum and duct tape.  I threw up a 12m inverted V, apex at 18ft, ends at about 12ft, with zip ties, a watering can holding down one end, a ladder on the other, and a fiberglass mast tied to the wrought iron grating on the front porch with clothsline (xyl lost her marbles when I said I was going on the roof) in four back-breaking hours with big help from Terry, WB6PVU. RG8x feedline coming through the front window with open coils on the living room floor made the xyl ecstatic and kept the cats amused 
Today I waited for hours for propagation to come up, and as soon as I could reliably hear VP6R, I started banging away with the K3 and KPA500 squeakin' from the freakin', steam coming off the rg8x.  Now I'm in their log on 12m cw!
Ham radio--still exciting after 47 years.
