Denon AVR2309-ci Tuner setup

[jc480]

My receiver is set up to a 7.1 system...everything is working fine...BD player, OTA atsc tuner for TV....

Now, trying to setup the tuner

- coax from OTA antenna to back of converter box...HDMI from converter box to denon receiver....coax from converter box to denon coax1 location

I go to Tuner setup...Input Mode: Analog...auto scan for channels....music set for stereo...Video Select: Source (guessing this doesn't matter)...Source Level: 0db

I see the tuner signal broadcast to my TV...

chA FM 89.10 MHz

No music is playing and I do get indicator lights on front of receiver...do I need to tell the receiver to use Coax1 for the Tuner? I can't find this setting in the menu if so....guess I'm stumped here

Is the tuner the wrong thing to use for FM/AM radio stations? I have a nice attic antenna that gets stunning digital tv signals and is a combo signal receiver (Channel Master 4228HD) so it should pick up everything.
