Hello Chuck, From my past experience with K3, the stock 2.7Khz was quite good. How about try it first ?

Chuck, If you are going to get "hot and heavy" into SSB contests, then yes, the 1.8 kHz filter is a good choice. The 1.5 would be even better in really tight situations. However, you said you were just returning to ham radio - so it may be that you just want to 'get your feet wet' in contests at first. If that is the case, then you may want to defer the decision on the 1.5 or 1.8 kHz filter. The DSP bandwidth control is normally adequate until you have close in stations with S-9 +40 dB signal strength at the front end of your K3 - those will create some pumping of the Hardware AGC, and that is what the more narrow roofing filters will help with. So if you can tolerate that condition for a while, defer the decision on the 1.8 vs. 1.5 kHz filter until you have simulated their effect with the DSP Hi-cut and Lo-cut controls to determine if the narrower bandwidth is agreeable with you - then purchase the roofing filter that you will be satisfied with 1.5, 1.8 or 2.1. Note that SSB signal tuning gets more critical as the filter width is reduced. 73, Don W3FPR Charles Teeter wrote: > Hello, All: > > I靶e made the decision to buy a K3, but before I do, I would like to solicit > some recommendations from you.
