Hi Scott,
I've fiddled with one of these (though I don't own one) and
understand that the jack you're referring to is a headphone jack
*and* a headphone extender jack. Griffin's link to info on this jack
is hard to find so I've included it for you below. Apparently hooking
up headphones or and audio extension cable to the second jack
improves reception. Link is below.

Hey folks, just wanted to ask a question on this unit. Well I guess
I was expecting a bit more, but was disappointed in the units
receiving abilities. It was rather depressing and I know its
environment has a great deal to do with it, but well Guess I was
hoping it could do better. I had some plans, but well to bad.
The question is there is a jack in the rear just above where the
usb cable goes into the device. My buddy and I were mucking about
with it and he looked and found no reference to it in the manual.
Is this jack for an external antenna? I didn't think so being as I
tried one that came with my shortwave receiver and figured it might
help with am reception, but no dice. I'm not sure how far usb
cables can be extended, but perhaps my only hope is to move the
thing out of my office which doesn't have windows and has to much
noise from the computers and router in here. Yeah I know that
contributes to the poor signal, but I guess if it had a telescoping
antenna it would have a much better chance. Will say the software
is pretty friendly as far as I could tell. It also seemed to me the
usb cable is a part of the antenna, but maybe I'm wrong. Its a neat
item and has some potential uses if I could get the reception
problem resolved, but well can't put a window in so an external
antenna of some sort is my only real hope.
tnx
Scott
