I had a quick question... my police department uses Motorola EX600XLS's for their portables and the CDM1550LS+ for mobiles. All the radios use MDC1200, however I was listening to an acutal officers radio, and the MDC sounds differant than it does on my scanner. The MDC isn't as long, it almost sounds like a milisecond bleep rather than the normal whole second of the data. What is this for, and is it possible to get my scanner to do it? Thanks!
