(CWID-51B) The heart of a CWlD is a plug-in ROM, factory programmed with call (or message). All CWD's are ready to install. CWID 50 (or rack-mounted 50R) automatically transmits station ID at precisely timed (adjustable) intervals.For repeaters(orAM, FM, SSB, or AFSK rigs). Power: 7.5 to 30 VDC. CWD-51 has all features of CWID-50, plus a 120 VAC power supply, monitor speaker, switch complement, and automatic switching to a DC source if AC power is lost. CWD-49 is an automatic message generator. For CW, RTTY, or any audio modulated rig. Push button (or remote contact closure) initiates pre-programmed message.
