The DMK one has all the interfacing parts, and everything is nicely brought to a 25 pin d-shell connector for you. The hacked one requires you to do alot of difficult and sometimes mechanically flaky modification, soldering, etc.

Subject: [App_rpt] usb radio interface

After looking at the info at http://app-rpt.qrvc.com/ it looks like there are 2 ways to go for usb radio interfacing. What is the difference between the modified usb sound fob and the dmk engineering interface?
