3.2.31 Maestro CW Keying Slow RX Recovery

I have a 6500 with a Maestro and software 3.2.31. It seems to be performing well on CW.

Has anyone else noticed that when listening to audio through the Maestro there is a slow and choppy recovery from transmit to receive when keying using the Maestro key jack and internal keyer?

The delay is only about 30ms but is annoying and in a contest, you would miss the first letter of someone who is responding quickly.

I have tried AGC set to FST. Delay set to 40ms or more eliminates the problem since the delay is longer than the slow RX recovery. I tested with other DSP functions off.

If you key the radio directly instead of the Maestro I have noticed no issue.

Bottom line, it appears you can't do QSK using the Maestro internal keyer. Is that right or am I missing a setting?

    If you are contesting, your snappiest connection path is to ensure that the Key is connected directly to the radio, not to the Maestro.

    We do recommend that for all contesting situations if you are able to do that.

    Latency due to WiFi and LAN is noticeable for higher-speed CW operators. Audio is also much faster when your headphones or speakers are direct radio connected.

    Give that a try. You can still use your Maestro as you are now.

    I experience that delay as well. It actually seems better with 3.2, but I have so many other 3.2 issues right now I wish I would not have updated.

    My “solution” is to MOX the Maestro during Keying. Somewhat okay for causal QSOs, but this is an awful workaround for contesting. It also helps if you turn the RX volume down and the sidetone volume up. But again, a poor contest workaround solution.

    Have you tried to set filters from auto to a different level? It may reduce latency.

    Pat, like you said "MOX" is not a solution. Changing the audio level had no effect.

    Volker, the problem is there for all filter settings.

    Thank you both for your suggestions.

    The problem is only with the Maestro connected to my 6500 through an ethernet switch also connected to the router. The problem is only when listening to the audio from the Maestro and keying the radio from the Maestro.

    No problem with audio and CW connected directly to the 6500.

    @Mike Connecting headphones at the radio also permits hearing the N1MM CW keying - Since day 1 with pre-release SMARTSDR V1

    @Stan VA7NF Yes, this is correct. K1ESE was referencing listening via a Maestro.

    As for the CW Sidetone, the CW Sidetone is delivered on the device doing the keying, and when using N1MM with the WinKeyer CAT connection this translates to CW keying on the physical radio and that is where the SideTone is generated.

    We are gravely aware of the requirement for the N1MM generated Sidetone to be tunneled back to the active listening position.

    Mike -

    You answered the question and I have marked it as such.

    The contest problem is fills. The canned messages from N1MM+ are great, but if you need a fill like "QRX one" or "VA3?W" you risk garbled CW.

    The bottom line is that the Maestro is not good at sending CW for remote contesting requiring accurate CW. Rag chew, no problem but when you need to send callsigns perfectly it's not good.

    This question was about the RX turnaround and that is also subject to occasional dropouts. I believe your answer is that is what happens when headphones are not connected directly to the radio. That's impossible in a remote setup. I have entered a HelpDesk ticket on the transmit issue. I had hoped that the timing improvements in 3.2.31 would correct the defect #7378. It appears not to be the case.

    For remote contesting my workaround is to use RemoteRig boxes instead of SmartLink. RemoteRig is faster, you get the sidetone from N1MM+, and the keying is better, although not perfect, if you play with the 'jitter' settings.

    Oh well...
