• The Datong FL-2 is designed specifically to improve reception of SSB, CW, RTTY and AM signals in interference conditions. It features twelve poles of tunable active filtering, independent low and high-pass filters. It can remove "monkey chatter" or "splatter" to SSB signals, remove heterodyne interference to AM and SSB signals, optimize bandwidth for RTTY, FAX and SSTV reception. Simple push-button selection of the three main operating modes: SSB, SSB+PEAK and CW. Connects to any receiver's headphone or speaker output. Requires 10-15 VDC. 7.2" x 6" x 1.7"
  
  The Datong FL2 contains the same filters as the Model FL-3 but without an automatic notch filter. Both the FL-2 and FL-3 are made in England.
