[Feature Request]: Tune function for antenna tuners

[deejdeej]

Problem Description

Add a second tune button, or make the existing tune button user configurable to send out a solid tone that can be used to tune an antenna tuner. First press activates transmits the tune tone, and it stays transmitting until pressed a second time to stop the tune transmission. This allows plenty of time for an external antenna tuner to process and select the best SWR.

Proposed Solution

The current tune button does not stay transmitting long enough for some antenna tuners to work. A solid tune tone seems to work better on some antenna tuners for matching SWR versus sending a data packet.

Alternatives Considered

n/a

Additional Information

I am thinking of the use case of an external antenna tuner. For example, I have a Hardrock-50 external ATU/amp attached to one of my radios, and it requires the radio to be transmitting a signal then press a button on the ATU to start the tuning process. When using WSJT-X, I press the TUNE button which transmits a tone (not a data packet) which allows me to press the button on the ATU to start the tuning process. Once the ATU is finished, I then press the TUNE button in WSJT-X a second time to stop the transmission.
