Product no.: BX-817-USD
Easy to build external Dynamic Compressor especially for the Yaesu FT-817/818, but can also be used for other transceivers with the same microphone interface such as the FT-857, FT-897 or FT-900.
When transmitting SSB, dynamic compressor increases average transmitted power, and thus the audibility of a weak signal at the distant receiver, by at least one S-unit. This accessory is of special interest to amateur radio operators who work with lower transmitting power or wish to be better heard in a pile-up.
Based on SSM2167 (Analog Devices)
PCB with all SMD parts preassembled.
Powered over RJ45 cable (10 mA), no power supply or battery required.
