DSP-based radio receiver
The M4FM-HD will stay locked to an HD Radio stream (HD1 and multicast) during power or data interruptions. The 700MHz ARM microcontroller and DSP with on-board flash memory can be updated remotely. The bright OLED displays RBDS and HD Radio PAD, audio level, digital audio quality and carrier quality indications. The receiver can be updated in the field to add TimeLock to maintain perfect time-alignment of HD Radio MPS analog and HD-1 audio and FM Translator+ composite output, variable IF bandwidth and ContentStream. The unit can be factory-upgraded with a DVI USB Port so unit status and all webserver fields can be viewer via an attached LCD monitor and keyboard.
