Direwolf includes a program to compare modems side by side.
Firstly make sure the modems are running then run aclients with dev or port number=modem type e.g.
aclients /dev/ttyUSB0=KISS 8000=DireWolf
Every 30 mins a count of the number of packets decoded by each modem is listed.
I’ve only tried this with Linux.
