DTMF Control Not Working

Anthony - N2KI All Messages By This Member #362 Any DTMF tones being sent to the node through the DINAH board do not see to be making it to the Pi for control.? There is bidirectional audio working fine. The rig is? a Kenwood TM-V708. >? DINAH > RPi Does the DINAH board strip out the DTMF tones or is there an additional setup? to allow them to pass or be heard by the node. Thanks for any advice or assistance.
Steve-N8AR All Messages By This Member #363 No - DINAH does no filtering of the audio from the radio.? Usually this problem is caused by an incorrect setting of de-emphasis in simpleUSB or an incorrect RX level setting. Look at selection G in simpleUSB (Admin Menu 12)? De-emphasis should be disabled.
Anthony - N2KI All Messages By This Member #364 Steve, Thanks for the reply.? I did a bit more digging and found a document on the groups,io site regarding DTMF tones.? Interesting enough?before I had a chance to investigate what the problem was, it corrected itself.? But I did go in and recheck?the DTMF levels and set it to where it was balanced for voice as well.? Targeting about 3.5kHz.? Seems ok now.? But I still do not know what was corrected to make it start working.? Strange. ?
