[Elecraft] Subject: K3 SSB filters

[Bob McGraw K4TAX]

Yes, but with a 1.8 kHz filter, the adjacent QRM goes away as well.

One can't have good quality from a wide bandwidth if the adjacent 
station is splattering over into your receiver bandwidth. Something has 
got to give.   After all, it is communications quality audio.   Narrow 
the bandwidth to 1.8 kHz and adjust the SHIFT to better the quality and 
lessen the QRM.
