Is there a technical reason that direct CW over CAT is not enabled for the Kenwood TS-2000?

I note that when the TS-2000 is selected as the transceiver in the CAT settings in RumlogNG, the message under the CW tab for the “Transceiver” selection says, “The selected transceiver isn’t supported for CW keying.”

According to the TS-2000 manual, the radio supports CW over CAT using the same KY;/KS; protocol as the TS-480, provided Menu 12 is set to “BEEP Volume” above 0. I use the "TS-480" selection in the CAT settings rather than "TS-2000" for my TS-2000, and CW from my radios works without apparent problems.

Thank you for your assistance.

Few important commands for CW are missing. Was it for canceling the transmission? I can't remember, but there was reason for that.
Please note the RUMlog internal CW keyer, this one is more reliable and better integrated: https://dl2rum.de/RUMlogNG/docs/en/page ... al_CW.html

Tom:

Thank you for the response. You have reminded me of an old TS-2000 issue I forgot about.

There are no missing CAT commands in the TS-2000. There is just no clear method to abort transmission once it starts. In the TS-480 and other newer Kenwood radios, you can stop the message using an empty KY························; command. The TS-2000 ignores this empty message command.

According to the TS-480 documentation:

The fixed 24-byte length is used for the P2 parameter.
” “ (space) characters must be used for the unused characters.
These space characters will not be converted.
If all P2 parameter characters are spaces, the transceiver stops sending the message.

There is no documentation of this issue being fixed in the TS-2000 firmware. If abort send can be done on the TS-480, I suspect it could be added to the TS-2000. I do not anticipate this being done to an older, discontinued radio. I do not want to try to modify the firmware myself and risk breaking the radio.

As for your keyer, thank you for the suggestion. I will see if I can use it. I am using my own wireless TCP CAT interfaces made from ESP32s, so I should be able to make it work. (I do not like wires going everywhere, so I am trying to make everything wireless between devices.)

Thank you again.
