These guys make something like what you're after, they used to be called SuperAWOS, now evidently Potomac Aviation:
https://potomac-aviation.com/vlp/?gc...SAAEgIVU_D_BwE There's some of these around the US, at smaller semi-rural fields that wouldn't normally get an "official" Weather Service/FAA AWOS or ASOS. You click three times on the CTAF frequency, and an automated voice broadcasts current conditions, like an ASOS, only not on a separate frequency. Works OK at light-use fields, but if much traffic on frequency with position reports, etc., it kind of clutters up the radio every time.
Looks like they go worldwide, but i don't have any idea about approval/certification, or such. And, may be more expensive than you' want for your private strip.
