[Elecraft] Filters

[ab2tc]

Hi Bill,

For SSB use the LoCut/HiCut mode. Set LoCut for 300Hz and HighCut for 2700Hz
initially.  That gives you comfortable audio when there is no serious QRM.
If QRM from above in frequency bothers you, crank the HiCut down to 2400Hz
or even 2100Hz. If you have narrower crystal filters, like 2100Hz or 1800Hz
they will switch in automatically. Don't touch the FL button. If you have
QRM from below (assuming USB) unfortunately there isn't much you can do. As
Don says (in a different thread), cutting the lows much above 300Hz quickly
affects intelligibility. Lowering the HiCut also lowers the noise floor of
the receiver if you are listening to a signal in the noise.
