[What repeater is this?]

Hi!  New to GMRS, my Jeep club is changing over from CB to GMRS.  I've been interested for a long time, but the change gave me the impetus.

I'm trying to figure out which repeater I am receiving. Please help if you can.

I'm located in Westfield, Indiana (18 miles north of downtown Indianapolis.  I'm receiving on 462.6250Mhz and when I do a tone scan I consistently get a DCS tone of D411N, however I seem to block the signal when using that tone.

My closest repeater on that frequency is Venom625, but that is not the tone he is using.

Through the repeater network I have heard people from central to north/northwest Indiana, southern Michigan, and several places in Wisconsin.
