If the CWX speed control is linked to the current CW speed slider, then three separate rise/fall states are already included based on sending speed. The present waveform break points are at 20 and 30 wpm.
I measure approx. 8 ms symmetrical rise/fall up to 20 wpm, 5 ms between 20-29 wpm, and 2 ms at 30+ wpm.
I compared the CW-sideband-test-results from Adam AB4OJ between Anan 100D and Flex 6700 and was surprised about the difference of about 15dB@1KHz off carrier, although the diagrams are barely readable at the top 10dB.
When watching the panadapter from my 6500 in CW it ́s easy to see that at 1KHz from carrier the sidebands are 70dB down no matter if 1-100Watts output.
Would be nice to hear more from CW-operators about the impressions for the 6000s. My 6500 has not the popping problem that N4LQ has described.
The QSK with my preferred speed of 25-30WPM is vy pleasant and makes a lot of fun. The reed-relay is vy quiet with the flex under the desk - the vacuum-relay from my HerculesII-Mod.420 is much louder....
