YAESU XF-128SN is a narrow crystal roofing filter for SSB on the MAIN receiver of the FTDX101D and FTDX101MP. YAESU’s official options list identifies it as a Crystal Roofing Filter (SSB 1.2 kHz).
The filter operates in the 9.005 MHz IF path and limits bandwidth early in the receiver chain. This is particularly useful in crowded SSB conditions with strong stations close to the wanted signal.
The company imports, installs and supports radio-communication and internal company-security systems. Integra-A is a distributor of radio-communication equipment and accessories.
