[App_rpt-users] Radio relax

[Chuck Henderson]

Did you make the mistake of doing a "yum update"?  If not then you do not
need to do the 111 fix.

Also you might find that taking "RADIO_RELAX away may make it more
difficult to decode TT.  If that is what you find, then there are other
ways to fix the falsing TT problem.
What I did was to leave RADIO_RELAX in place but edit the line #165 in
main/dsp.c to be like this

#define DTMF_TO_TOTAL_ENERGY    ((digitmode & DSP_DIGITMODE_RELAXDTMF) ?
38.0 : 42.0) /* CAH was 26 now 38 */

Then recompile.  That change works very well for me in eliminating the
falsing without making TT too hard to decode.  You might also experiment
with different values to find just the right compromise for your
situation.  Just remember if you do this fix then you will need to re-do it
every time that you get new source code for an update.

Your mileage may vary a lot.
