[Elecraft] Selectivity

[Mike K2MK]

Hi Roger,

Take a look at your RX equalizer settings. If I remember correctly the DSP
will not apply positive DB equalizer settings at a bandwidth setting of
100Hz or 50Hz. So if for example your pitch is set to 600Hz and you have a
6db boost dialed in on your equalizer at 600Hz then when you narrow your
bandwidth you will experience a drop in audio level of 6db.

Again, if I remember correctly, the solution is to only apply negative db
settings for your CW RX equalizer. So you might drop all frequencies except
600Hz by 6db. Then when you narrow your bandwidth you won't experience an
audio level drop.

73,
Mike K2MK
