Ruffin, Grundig's Yacht Boy 400 P.E. is an excellent a.m. dx rig to consider.
Has pleasant audio so you won't suffer aural fatigue over extended listening
periods. Here in Sactown, it gets exemplary night-time reception of San Diego's
sports powerhouses XTRA 690 khz(although Vancouver B.C.'s CBU, with 50 kw from
1100 miles away, will occasionally extend it's co-channel blanket over XTRA's
72 kw signal, which is only 550 miles removed) & Sports XPRS' 1090 khz(Wolfman
Jack's legendary on-air residence). When San Mateo's Ticket 1050 khz cuts power
& changes antenna pattern @ night, that YB 400 does a good battlin'
propogational flutter. Plus you have the added benefit of being able to
off-tune away interference. When listening to Denver's KOA in the evenings,
gotta tune to 849, as 850 gets side splatter from Modesto's KTRB here in
Sactown. Not to mention decent sw & fm reception as an added benefit. If
you're in luck, your local Ratio Shaq should have one hidden in their discount
bin.
