As I understand it, the K3 generates a very clean CW signal with DSP. There isn’t anything to filter out.
A narrow filter might add distortion and make things worse. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Aug 21, 2018, at 1:42 PM, Byron Peebles <nz3o...@gmail.com> wrote: > > Don: > > I do understand it works, since every unit is shipped that way. > > My question is more in the vein of wouldn't using a 1kHz or less filter be > safer/cleaner/logical for CW? > > Obviously, not as a factory default, since only one filter is sure to be > there, but on a per-user basis. > > I thought years ago (before I had Elecraft) I read that a narrower TX signal > made for a stronger signal within that narrower bandwidth. > > 73, Byron NZ3O > > > On 08/21/2018 04:33 PM, Don Wilhelm wrote: >> Byron, >> >> The K3/K3S is designed to use the filter that is installed "stock" in all >> transceivers, so you need to select the 2.7 (or 2.8) filter for CW (or any >> other mode except AM, FM or ESSB) for transmit. >> >> Requiring a 1kHz filter for CW transmit would require that filter be >> included in the basic package and would increase the price of the >> transceiver. >> >> This sounds like a 'curiosity' question - the K3/K3S works fine with the >> 2.7/2.8kHz filter for CW transmit. >> >> 73, >> Don W3FPR >> >> >> On 8/21/2018 4:03 PM, Byron Peebles wrote: >>> I have noticed that Elecraft K3/K3S defaults to setting the wide SSB filter >>> as the CW TX filter. >>> >>> Is there a technical reason for doing this?
