The subfreezing cold made it tough to stick around in the frozen back yard
after around 1520, though, and TP signals were dropping off for the most part
by that time. Overall the session was one of the best of November, and
hopefully an indication of better DX to come.

I think you need to figure out a way to get the DXing indoors somehow, Gary.
Options:
(1) Varactor tuning of sizeable passive loop, pick-up link winding couples to
speaker wire or coax. feed back to shack. DC for varactor tuning can be passed
out on feedline through RF chokes / DC block cap's scheme, e.g. bias tee.
(Similar to how DXers are running remote Vactrol resistance control for
termination null adjustment.) Feedline signal can be coupled to INDOOR
portable via link wound on ferrite rod, or sent directly to a communications
receiver or portable that is equipped for low impedance signal input.
(2) Install passive BROADBAND loop in backyard (either terminated or
figure-of-8 type), bring signal into shack, link-couple to tuned loop used
adjacent to a portable radio, or go through a tunable preselector (active or
passive) en route to a standard receiver input. In-shack broadband
amplification (e.g. DX Engineering RPA-1) of the loop feedline RF is also
possible if you "allow" active devices to be used. Battery power would be
advisable to keep indoor noise sources out of the system.

Maybe try some one of these ideas and you'll be "the DXer who came in from the
cold."
