Did you mean do they have a CW ID for them?Do trunked systems like the CSP have a frequency for them?
CW is short for "Continuous Wave", basically an unmodulated carrier. In this case, the information is transmitted not by modifying the carrier (varying the amplitude or strength of the signal for AM or varying the frequency of the signal for FM) but by simply turning it on and off in a specific pattern (e.g. turning it on for 1 time period, off for 1 time period, on for 3 time periods, then off for 3 time periods would translate into ". -" [dot, dash, or dit, dah, if you prefer] indicating the letter "A"). The time period depends on the speed you're transmitting at where slower speed code (5 WPM for example) would use a longer time period than faster code (20 WPM for example).Reading a thread from Las Vegas and they say the new p25 system has its own TG for the CWID. What does CW stand for anyway?
n5ims summed up the meaning of CW nicely. It's also simply known as Morse Code by many. Although CW is more a form of modulation (it confuses you here as it is an un-modulated carrier in its true form!) and morse code is, well, morse code. Morse code can be sent with several different types of modulation and the more I think about it, I imagine sending it digitally is perfectly legal as long as it is not sent encrypted.Reading a thread from Las Vegas and they say the new p25 system has its own TG for the CWID.
