My guess is your using speaker audio and has more low end audio frequency responce than high's. This causes the dtmf digit 3 not to be decoded. I solved this issue by running fob's and a rail to rail buffer amp in between the radio and fob. If you want I can send a schematic of my design when I get home. </div><div><br></div><div>Eric</div><div>N7JYS </div><div>n7jys@yahoo.com</div><div><br></div><div><br></div><div><br></div><div><div style="font-size:10px;color:#575757">Sent from my Samsung Galaxy smartphone.</div></div><div></div><br><br>-------- Original message --------<br>From: Roselito de los Reyes via arm-allstar <arm-allstar@hamvoip.org> <br>Date:08/01/2016 3:25 PM (GMT-06:00) <br>To: arm-allstar@hamvoip.org <br>Cc: Roselito de los Reyes <tolitski@hotmail.com> <br>Subject: [arm-allstar] DTMF <br><br><div dir="ltr">Hi,<div><br></div><div>I created a simplex node and got it working.
