I could be off here since I don't have one of these radios, but the RR data is stored in the scanner memory, and the SD card is used to hold whatever it is you wish to monitor. If this is so, you would need to format the SD card, make sure the radio recognizes it properly then use the software to copy data.
Is my understanding here off, folks? I'm trying to think in KISS mode here...best regards..Mike
[edit] Come to think of it, this is a question that has come up in the past- I think a writeup of the exact procedure, step by step, that we can add to the FAQ would be very useful. It would, in fact seem to be similar for all of the OO scanners that use a SD disk...it would certainly help newcomers. If someone were to write this up in Word I have a converter which will change it to MediaWiki....
