We are featuring the products that won the Radio World Best of Show Award at the 2026 NAB Show. Winners were chosen by a panel of engineers and RW editorial staff for their innovation, feature set, cost efficiency and performance in serving the industry. Information about how the program works can be found in a FAQ here.
With new capabilities, the MPX-2c allows broadcasters to combine an HD Radio E2X signal from any Exporter with an analog or digital MPX signal into one synchronized stream.
Instead of managing separate signal paths, HD and FM are transported together and arrive at the transmitter fully aligned.
At NAB, 2wcom demonstrated this with a real-world setup. A combined FM + HD stream was sent from Germany to California, more than 5,000 miles, to show that the signals remained synchronized with SFN-level precision and no audible diversity delay.
The MPX-2c works with any HD Radio Exporter and supports both analog and digital MPX signals, easing integration into existing infrastructures.
By using GPS with a 1PPS reference, the MPX-2c maintains synchronization between HD and FM signals across the distribution chain. “This level of accuracy is sufficient for FM Single-Frequency Network operation and enables new approaches to network design, coverage optimization and spectrum usage,” the company says.
It supports uncompressed MPX from 1.5 to 6.1 Mbps for maximum signal quality, as well as bandwidth-efficient compressed MPX such as µMPX at around 320 kbps.
