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.
