G'day, The filters on K2 #1400 (fully updated):
Mode: CW AGC: OFF ATT: ON Signal source: K3 Frequency: 18120kHz Pitch Freq: 650Hz Measured using Spectrogram ref level for audio peak -90dB. The sound card in my PC isn't particularly good and this low level eliminates displayed audio harmonics. Filter: 1000Hz -90 (ref) 700Hz -90 400Hz -92 200Hz - 94 FWIW.
