What are the different options available for Motorola MDC 1200 signalling? I know it can be set up either when PTT is pressed or when PTT is released.... any benefits to a perticular way its set up?
Also how does the encode/ decode feature actually work? Would both need to be active to receive Id's and transmitt my own to other radios?
thanks in advance

I can't answer the first question...
But you must have both encode and decode enabled to send/decode MDC1200 Id's. Encode means you are sending your ID, decode is when your radio receives the MDC120 databurst and decodes it into an ID or alias to display on the radio. Also note that not all radios are capable of decoding, but most later /\/\ gear can encode.

Depends on the model. Some only allow one or the other. Most of the newer radios (1990's up) will support pre and post. The only catch is that some radio's will only allow pre if encyption is present in the radio (Sabers, and spectras).
Most radio's will not display the ID on the radio front of a display radio. The current Pro series will, astro's with the proper flashcode etc. The radio sends and recieves a 4 digit hexadeciemal "number" 0-F.
If you see any radios that will display a name, its because the ID to name "alias" was programmed into the radio. No actual name is sent.
As for benefits, I haven't found any. What I always did was set them up to Pre so that people wouldn't talk into dead air if there was a repeater delay, or what have you. Another side benefit with the pre sidetone, is that you have an audible warning in case its keyed by accident (think of telling a really bad joke and have no way of knowing that your transmitting it to all the hear).
For places where people didn't care or hated the sidetone, they would use post. On the radio consoles, most people like to know who is calling before they hear the voice. Pretty much a local choice. The trend lately is people going with post.

Lowband radio. The original and non-complicated wide area interoperable communications system
