[Simon Ravnič]

Hello,

my user, S51ZO is often spotting beacons and complained to me that he gets wrong duplicate warnings.

This is what I found out:

2025-05-15 18:27:07 GMT 10368070 S55ZMS/B   -> DUPLICATE

So it appears that any two spots with the same callsign get compared, regardless of frequency. How long is deduping timer? 

Is this a bug or a feature?
