Is this FM over-modulation?
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?

What’s your proximity to the transmitter? At least on AM I’ve seen splatter from nearby strong transmitters which don’t splatter once a reasonable distance away
Less than 5 miles. Their signal strength is s9+60 or so. Definitely strong.
That’s a lot of power coming straight to your radio. Does this model have an attenuator or RF gain? Try turning it on (or down the RF again) and see if there’s still splatter.
Indeed. Unfortunately those fancy features aren't available on vhf/uhf with this radio. Only the hf bands have those options.
