Is this FM over-modulation?
Listening to a local repeater and the waterfall display shows some pretty wide modulation whenever the repeater is in use. If I'm showing +/- 50kHz on the scope then the repeater's bandwidth is frequently 20+ even 60+ kHz.
Given that FM voice bandwidth is typically less than 15 kHz, this would indicate a failure somewhere on the repeater tx side of things right?
