I spent a lot of time with the K3 this weekend working SSB and data modes mostly PKS.
The K3 the more I use it the more I like it and am amazed by its performance with a standard 2.7 5 pole filter and 2.1 8 pole filter. First for ssb I was joining a new that had .5 khz signal above the net signal. I was able to dial down to a .95 khz filter and shift it such that I could still join in on the roundtable net. It was absolutly amazing. Then I spent a ton of time on the digital modes. I wanted to try and make a lot of contacts and use the extra punch you get with these narrow signals. First I have learned that PKS guys dont care if they get right on top of your transmitt and receive. I was able to narrow down to .15 khz on the dsp filter and could eleminate completey the interference from nearby signals that would get hammered by the qrn. I do not believe that everyone has a K3 but that they depend on the computer extra filtering. However, I could eleminate the close signals with the K3 which greatly enhanced the copy. Finally I learned really dial in my output from the pc for the digital modes so that the ALC would be at a solid 3 bars and just tickel the 4th bar. In this condition I could go to 100w out and still have a clean signal. I was able to punch some dx at high power that i could not get at 50w or less. Spending a lot of time over 50w and the PA temp never went above 43C. The more I use it the better it gets. I can only wonder how much better it would be with a 500hz and 250hz filter. Also if the new amp is as clean for 500w as the standard 100w built in amp it will be a winner. Now how to save more money for my two hobbies. One is ham radio and the other is my Jeep (Just Empty Every Pocket). I wonder what I could do if I had more than a dipole at 30 ft.
