Off topic comment on the back yard vertical issue...
Ground mounted verticals just don't really work for 20 Mtrs and up. I read
on some newsgroup eons ago that the physics of the antenna means it won't
radiate much above 10 MHz. I've had a back yard vertical--admittedly with
ground rods but no radials--for almost 30 years and it's performed
reasonably well on 40 (worked 9G0ARS in one call on 7002 this evening), but
replaced it with dipoles for 20 and up early on.
You think operating form a small urban lot you own is tough for DX'ing and
contesting--try a rented apartment in Brooklyn. :-)
