REGENERATIVE_CW_FILTER
Can be added between product detector and volume control of SSB receiver or transceiver that does not have CW filter. Just before oscillation oceurs, gain becomes extremely high with very narrow bandpass. Regeneration and bandpass can be adjusted as required. Filter typically has 40-Hz bandwidth centered on 800 Hz.-R. A. Yoemans, Further Enhancing the Yaesu FTDX-560 Transceiver, CQ, July 1972, p 16-18 and 20-22.
