I don't see that as being realistic. Per the normal definition of a Morse "word" being the word "paris", 300 wpm means each dit would be no longer than 4 msec. As best I can recall, the rise and fall of the K3 keying waveform are each around 2.5 msec. I'm not at all an expert, but I suspect most digital signal processing techniques would find that hard to differentiate.

Greetings list! I searched the archives and other sources, but haven't found an answer, so I'll try here. I'm looking to find the maximum cw speed on my K3 (with new oscillators, serial 8xxx) when using a manual cw key plugged into the KEY jack on the back of the radio. I don't mean the internal keyer, or memories. I'm not using QSK, so that won't be an issue. The K3 is put into TX mode via an external TX switch, and keyed via the KEY jack. I'm hoping for speeds in excess of 300 WPM. Possible?
