Hi Ivan, I am a CW guy and agree with John's assessment on the number of answers you will receive!
Here's mine: I run 250Hz, 400Hz, 1000Hz, and 2.8Khz. I know folks out there will say that the 250 & 400 are so close in filter shape when you really take a look at things, that they are somewhat redundant. If you want to cut down on initial expenses, I would start with the 400Hz filter, this will serve the double duty for CW and your occasional dabbles in the digital arena. They are somewhat easy to add at a later date, depending on what other options you have added, which also gives you the opportunity to learn a little more on the workings of the K3. As far as SSB, I can't comment, as I do not even own any microphones! One thing for sure, you will be a very happy CW operator once you learn your way around the K3... it is a fantastic radio! 73 de Jim - KE8G ---- John Lemay <j...@carltonhouse.eclipse.co.uk> wrote: > Ivan > > You'll get as many different views here as there are combinations of > different filters ! > > Roofing filters are quite easy to add at a later date (ease depends somewhat > on the options installed), so my suggestion is to go lightly at first and > see how you get on with just a couple of filters, and rely on the DSP for > filtering - which is pretty good. > > For SSB, consider either 2.4 or 2.1kHz.
