I got one for Christmas. And I've given most of the functions a pretty good
workout -- except the shortwave. The AM/FM/XM reception is very good. But
all the Eton reviews I've seen are for the E1. So, I'm not sure how the
P7131 stacks up for shortwave reception. There's an external antenna jack
on the back, but the manual doesn't say whether that's for AM, FM,
shortwave or some combination of those. Does anyone have any experience
with this unit for shortwave? And does anyone have more info on the
external antenna jack?
