210 FM RECEIVER                

Model 210:  FM, FM/SCA, FM/RDS Monitor/Receiver

A precision FM broadcast receiver with composite and optional SCA and RDS demodulators.  All designed for the most demanding sensitivity, distortion, and signal to noise requirements.  The Model 210 is single channel with PLL (synthesized) tuning.  The Model 210 was designed for professional broadcast requirements including FM relay (translator) service, SCA monitoring, data, and paging service.
