            Hi David,

             

            I think that if the audio is lowered the DTMF will work but the voice audio cant be herd. I have my embedded node hooked to my RLC-4controller with the jumper taken out of the controller for flat or spkr audio. The audio is great and balanced so not sure why it wont work. I know Shorty K6JSI controls his network and has no issues. Must be something im doing here or Chris K7UND on his node 3153.

              The DTMF_REGEN dtmf comes out at "100%" I think by default, or it's
              settable somewhere...

              Dave may have added that later on, I can't remember...

              50% of full PCM audio is more than plenty on a properly set up node
              that was set up with a Service Monitor... so if REGEN doesn't have a
              way to turn that DTMF down digitally when it's generated Dave, it
              needs it...

              But I think it's already in there as a setting somewhere, Mike. I'll
              have to go look... got a Net to get on in 15 minutes first, though...

                Hello Everyone,
                 
                Mike and I have been doing a BUNCH of testing and we have it narrowed down to this as our issue.  The first part of the digit that is being heard at the far end (here in Oregon) is screwing up the repeater controller because it hears it and hangs on to it.  So, if Mike enters 12345, because the "1" is shortly played, my controller hears 112345.  So, if there is a way to get the script for DTMFREGEN to do an unkey before it keys up again to do the DTMF regen that would work because an unkey will clear the buffer on the controller.  It sounds like it is supposed to do this but it is not.  When Mike in Colorado keys up and enters 12345, here in Oregon I hear 1....12345 with NO unkeys between the first blip of the digit and the string to be entered.
                 
                Does this make sense?  Can the DTMF Regen script be modified to first UNKEY after DTMF is heard and then Re-key to generate the DTMF?  I would think for people like myself that have to use the IRLP machine on the repeater frequency pair would be having this issue and a simple unkey of the node before a re-key to generate the DTMF would fix it.  Unfortunately I know nothing about scripts or writing them.
                 
                Please help....
                 
                Thanks!

                  HI David, I just spoke with Chris K7UND in Oregon and he is resetting his node. I belive the problem is with his side since he can control my embedded node
                  Message 8 of 13 , May 15, 2008

                    HI David,

                     

                    I just spoke with Chris K7UND in Oregon and he is resetting his node. I belive the problem is with his side since he can control my embedded node just fine but when I try to control his controller that is where things get dicey.

                    A 2 second delay was added earlier today. Perform a update files or
                    reset your nodes, and try the system again.
