Also I was told by someone at flex there would be pin diode cw keying available as a user option. If this was in the design I imagine it is already in there but not yet available in the software?
As a primary CW op there is absolutely no audio popping here. I too use a WinKey USB Keyer. As one of the Alpha testers I particularly pay attention to CW performance. My delay is set to zero.
The pin diode is in the system and works. It is only engaged above a particular speed and I don't remember that number.
I have no popping at any speed.
All of the CW Sidetone is generated in the radio so the computer should not be an issue.
The slice shows QSK...see pic. But this is even with the delay set to 280. I understand that the QSK indicator is only supposed to come on if delay = 0.
Mark - If the T/R relay for CW is a pin diode then why do I get all the relay chatter when keying with delay set to zero? I would expect the radio to be just about silent when keying.
Let me answer that question myself. If you recall I am on a bunch of meds including pain meds for a severely pinched nerve in my lower back. Had another cocktail of delaudid and toradol today too. I am getting the relay chatter....fortunately it is coming from my amp next to the radio....the way things are set up it sounded as if it was coming from the radio. My bad!!
The popping or artifacts I think are still in there. The way I feel right now maybe it is either my imagination or just to critical. For 6 years I have used a different rig whose QSK is the best I have personally used. This comes close but I don't notice the popping on that rig. Maybe popping is a poor term. Maybe its the aggressiveness of the RX coming back after each break.???
Glad I realized my foul on the relay noise.
here my comments:
External Key K1EL. 25 to 90 WPM
Output Power slider on 100W
1. RX = ANT1, TX = ANT1
Speed slider (SSDR) set to 100 WPM.
K1EL - 25 up to 90 WPM (test)
RESULT: QSK Ok, but not realý hear between the characters.
Speed slider (SSDR) set to 5 WPM
K1EL - 25 up to 90 WPM (test)
RESULT: BAD, you will heard you own signal pumping
Important question: Way there is dependency between internal speed slider settings and the QSK in ALL caces?
Exactly under the 20WPM of the Speed slider (SSDR) you will heard pumping.
Over 20 all OK.
2. RX = RXA, TX = ANT1
RESULT: BAD, you head relay klicking on every single charachter IF the speed slider (SSDR) is on 100WPM
IF the speed slider(SSDR) is on 5WPM you will heard relay klick only with the first one (like semi break-in) .QSK symbol in the slice is aways NOT activ.
3. RX = RXB or XVTR = QSK, TX = ANT1
RESULT: QSK is OK & no relays clicking. QSK symbol in the slice is active. But under 20 WPM on internal speed slider (SSDR) you will hear signal pumping
IMPORTANT: All tree behavior are the same with the internal IAMBIC (SSDR) key ON and only external paddle.
I thing you have some bad bugs with the new version.

Steve, N4LQ suggested using a dedicated gigabit LAN card in my PC for the Flex 6700 connection. I ordered a new board online, price was about USD $10.
In my case, CW QSK is now equal to the K3, even when using an external keyer. It was good before, it's superb now. Gone are the switching artifacts (clicks & pops) in the headphones and audio can be heard between high-speed keyed elements with Delay set to zero. This still means the SSDR speed slider must be set to 20WPM or above to avoid a well-known switching artifact when the slider is at 19 and below.
Installation took a few minutes and SSDR found the 6700 right away. If you're a die-hard CW QSK user, consider adding a dedicated gigabit LAN card to your PC.
