I do not know about the D-109, but the D-808 has RDS capabilities for FM BC.
You will find this very helpful in identifying FM stations when you are DXing.
The Worldwide TV FM DX Association has a Database of FM Broadcast Stations that really helps out.

The D-808 works nicely with its internal whip, but really works better with just a simple set of Rabbit Ears measured to frequency (234/Freq MHz= Leg in feet) as a Dipole.
Demo on one of my old portables: Be sure you match it with a (old ones 300 to 75 ohm) Balun.

I really look forward to FM DXing this April when I move into a new house farther away from the Dallas/Ft.Worth Metromess.
Good Luck

By the way... 

I make available each April an export of the licensed FM Broadcast stations from the FCC Database in an EXCEL spreadsheet. Just in time for Sporadic Es Season.
I did this with Bob Colyard  (DXWorld.com) when he was alive before his and the Website's demise.
I hope the move doesn't interfere with me getting it done this year.
If you are experienced with Spreadsheets, it really helps you out when DXing.
There are a lot of good tools out on the Internet, but I always go back to this one to isolate what's out there.

Have fun.
