Description

I think there are several ways lost and found mode could be improved:

• Reduce power in lost and found mode
• Enable precise location to avoid sending imprecise locations
• Reduce battery usage (Could stop forwarding packets)
• Allow position requests
• Make the node emit RF in a way to make it easier to direction find by making it a unique signal. (Doesn’t have to be Lora)

My two cents:

• SX1262 and most likely other chips support regular FSK modem so direction finding beacon could be triggered in the form of a relatively long FSK burst on a different frequency - while still meeting ISM regulations.
• Add support for a buzzer in meshastic tracker so you can remotely trigger audible tone/alarm.

But at the beginning we should agree on what is really required from this mode because documentation is pretty vague - even how to enter this mode because this is not something that you probably should/want to set in advance in the config.
