There are at least 2, or 3 different versions of the DX, so be careful which one you get, or you'll need the pigtail adapter for it to cover 11M. The ones that HRO sells have a "green dot" sticker on the box, & inside the radio. Those are the ones that require the $$$ pigtil. I bought one of them, and it didn't cover 11M by just installing the jumper, so...
The ones that have the "red dot" sticker on the corner of the box are OK though, from what I remember and only require the jumper to complete the conversion. After the conversion, you will be able to go from 24-32 Mhz. Good luck.
