dtmfout problem

[skimask]

I do not read good frequencies with my scope, maybe it is because of DTMF, this is the first time working with this this. I posted a screen capture of my scope while the dtmfout id dialing 5 constantly.

Are you set for AC or DC coupling on the 'scope?

[lerameur]

I tried both DC and Ac and I get the same result, ground coupling gives me nothing.

lerameur, Attached is the DTMF filter I use on the remote links I have designed and the repeater controller as well as the 6 channel voter for an amateur radio system here in detroit. Try it....
