So is it possible, maybe in the right area and with the right setup, to have CBK and XEWA both coming in at midday in June?
For example, if you're in western Wyoming, Colorado, Nebraska or Kansas (dodging KYAH, KNMX, KDFT and KWMT), bonus points for doing it next to KRAI's transmitter,
and maybe rbrucecarter is using his Superradio, 10-foot loop (or whatever is the largest he has) and an inductively-coupled Beverage antenna,
Could you have reception several dB-decades stronger than
this? (that's 1390 XEKT & KLTX at Pacific Beach, CA, on a SRF-59's internal ferrite one early afternoon.)
Or what about hearing 800 XEROK and CKLW in Kansas City? Or could there be another place/frequency to regularly hear a Canadian
and Mexican station simultaneously, each strong enough to stop a scan, when the sun is high in the sky?

(and no cheating with tropo/skip/etc

)
