[Elecraft] Full Break-In (QSK)

[K9MA]

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.
