2600 not recognised

Closed this issue · 2 comments

I have called to Project MF station and it didn't pick the 2600 tone from Flipper.
Not sure if the mobile network compressed it or anything else went wrong.

It's likely related to #6. The tones coming out of it just aren't actual sines. Also as noted in the readme, the 2600 tone is off by a few Hz due to the sample rate.

Closing issue. It's known that the approach is imperfect.
