Special Functions

• AM dual conversion
• Single Side Band (SSB) with BFO control
• Synchronous Detector: Upper Side Band (USB) and Lower Side Band (LSB)
• AM Bandwidth selection (wide / narrow)
• Air Band (VHF): For intercepting radio communication in aviation – e.g. commercial and general aviation, radio navigational aids, air traffic control. By using your PL-660s air band function, you may intercept communication between pilots and the air traffic control, but also other communication from commercial and general aviation, radio navigational aids and air traffic control.
• Auto-sorting memory: sorting stored stations automatically according to meter band and frequency, removes duplicate stations.
