TECSUN PL-660 is a PLL AM Dual Conversion radio receiver for listening to FM, Longwave (LW), AM / Medium Wave (MW), Shortwave (SW) and VHF Air Band, and it is Single Sideband (SSB) capable.

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.

Frequency Range:

• FM:   76 – 108 MHz
• 76 – 108 MHz
• 87.5 – 108 MHz
• LW:   100 kHz to 519 kHz (tuning step 1 kHz or 9 kHz)
• MW:  520 - 1710 kHz
• 522 - 1620 kHz (band step 9 kHz)
• 520 - 1710 kHz (band step 10 kHz)
• SW:   1711 kHz to 29999 kHz (tuning step 1 kHz or 5 kHz)
• AIR: 118 - 137 MHz (tuning step 1 kHz or 25 kHz)

Tuning Methods:
