Good morning All. I am looking for the message that Jim WB6NIL put out there that had to do with modifying the dsp.c code so that it did not incorporate the RELAXED_RADIO parameters. One parameter is the length of time that a DTMF signal must be present before it is determined not to be a false signal. [root@Server6 main]# diff dsp.c.default dsp.c
165c165,166 < #define DTMF_TO_TOTAL_ENERGY ((digitmode & DSP_DIGITMODE_RELAXDTMF) ? 26.0 : 42.0) --- #define DTMF_TO_TOTAL_ENERGY ((digitmode & DSP_DIGITMODE_RELAXDTMF) ? 38.0 : 42.0) /* CAH changed 26 to 38 */
This change when implemented, did eliminate a noticeable number of audio pops associated with DTMF false-ing. The message from Jim spoke to bypassing the RELAXED parameters in total. I am going through the archives and I have not found it yet. Thanks in advance. Keith -- keith@goobie.org Keith Goobie Richmond Hill, ON, CANADA
