That one has a "bad checksum", so Hijack ignored it.
Stalk: in=02 00 ff ff == no button
It gives me nothing on the Hijack Button Codes display.
Yeah, 0xff is the *only* stalk report that Hijack does NOT show on the front panel, because it means "button released"
So what you got was a 0x00 "button pressed (but bad checksum)", followed by a "button released".
Mmmm.. I wonder if it's just the checksumming logic that's busted on that tuner?
Here's a copy of Hijack that disregards the checksums:
