Well, i don't know if it is a timing issue or a hardware issue, but increasing the RFM95_POWERUP_DELAY_MS from 10 to 100ms solved the issue.
Now testing range improvement over rfm69h, will report back.
@tekka , Great work !

@NeverDie
Excelitas PYD1588/1598 are the best I've used, running now for years without a single false alert.
Fully integrated, 1.8V and only 3uA

Pcbway do produce better finished pcb, but the big advantage of jlc is their SMT service

You should define MY_SIGNAL_REPORT_ENABLED

@nagelc
I kept all setting to default except the maintain window =8s
So the SERIN reg is: 0x0031ED10

@NeverDie
With the fresnel and the wide angle 1598 it's ~ 7m
