I recall reading *somewhere* the story of two hams that lived in
adjacent lots about 300-500 feet apart. They cooperated and tried lots
of remedies to eliminate interference with each other. They each wound
up with a K3. When the upgrades for the 'S' became available, both
installed the appropriate options in their K3 radios. After that they
could operate within 10 KHz of each other without knowing- at legal
limit. YMMMV

Hello Joe,
I am in somewhat the same situation as you are, just not as bad... I
have a KW level Amateur living about 700 feet from me. I had a K3,
and as long as we were not within 50 KHz of each other, he really did
not bother me, save when he was hammering his ALC-- but that is a
different story...
I also have several other Amateurs all living maybe 1 to 2 mile from
me. All running 500 to 100 watts.
I was very worried that the K4D would have issues with any of them
when they were transmitting.
So far the K4D had behaved as the K3 did, some interference, (not
much), when the KW level fellow comes on line, and only on the same
band. I have tested other bands while the KW level ham is
transmitting, and if I am on a different band, I can not hear him...
With regards to the Amateur running 500 watts a mile from me, the K4D
behaves marginally BETTER than the K3 did.
That is not the same as having another ham a one wavelength away, as
you describe, so your mileage WILL vary... I will NOT be purchasing
the HD module, as it appears I do not need it...
My guess is you will see worse performance than I do, due to your very
close proximity to the other Amateur, but I can't predict how much
worse... The K4D is remarkably tolerant of strong signals.
73, and thanks,

I share a property line with another ham. Some of his low band wires are
within a wavelength of my vertical. When he's transmitting, I rarely
notice with K3 unless I'm really close. The IC-7300, he can wipe out my
receive if we are trying to work on the same portion of the band.
I have my sights set on a K4D, but wondering if I should be
considering the
HD version.
Thanks & 73 de Joe NE3R
