Re: [Elecraft] New K4 feature: Dual APF bandwidths (audio peaking filter)

I didn't mean "all the time" as "whenever I operate." I meant "a great deal of the time." Sorry for the exaggeration. It's one of my favorite features. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 16/05/2020 14:50, Victor Rosenthal 4X6GP wrote: I use

I use the APF in my K3 all the time. The wide base with a sharp peak are very helpful for CW intelligibility. I would like the peak to have a little more gain, though. Maybe it could be adjustable in the K4? 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ O

[Elecraft] New K4 feature: Dual APF bandwidths (audio peaking filter)

CW ops, especially those doing weak-signal DXing and DXpedition work, will now benefit from a second APF filter bandwidth in the K4. The original bandwidth is 30 Hz, which is good for code speeds up to about 30 WPM. The second bandwidth selection is 50 Hz, which allows copy up to about 50 WPM.
