[Elecraft] Full Break-In (QSK)

[E.H. Russell]

As I recall the FT-1000D accomplished that by shortening the dits and
producing an astonishing clatter.

One of the things I miss is being able to hear between the dits, not just
the letters. I know part of that is due to the inherent latency of DSP
filters. In any case, I finally got around to actually measuring it. 
I just used a keyer with 50 percent weighting, and N1MM to set the speed. I
found that the K3 could just barely hear something between the dits at 22
wpm, while my old FT-1000D could at 34 wpm. Both at 500 Hz bandwidth, fast
AGC. The K3 has the new synthesizers. I did the test by listening to an S-7
carrier and sweeping the RIT back and forth while transmitting dits. Below
the above speeds, I could just detect the change in pitch.

Increasing the bandwidth and turning off the AGC didn't make much
difference.

I didn't try the QRQ mode on the K3.

It will be interesting to see how the K4 compares.
