Hello, my 12.5 kHz repeater system has a long noise tail compared to my 20 kHz repeater system. Both use the USB URI with flat audio and carrier from dsp in carrier squelch mode. Moreover the rxnoise tuning comes with a warning: db0fox*CLI> radio tune rxnoise tune rxnoise maxtries=12, target=27000, tolerance=2750 tries=0, setting=2, meas=15368 tries=1, setting=4, meas=21645 tries=2, setting=5, meas=26274 tries=3, setting=5, meas=25744 tries=4, setting=5, meas=26047 tries=5, setting=5, meas=26010 tries=6, setting=5, meas=26393 DONE tries=6, setting=312, meas=26393, sqnoise=5990 INFO: RX INPUT ADJUST SUCCESS. WARNING: Insufficient high frequency noise from receiver. WARNING: Rx input point may be de-emphasized and not flat. usbradio.conf setting of 'carrierfrom=dsp' not recommended. New repeater systems in germany are now limited to 12.5 kHz. Would be nice to build them with the Asterisk/app_rpt system. Are there any plans to adjust the code for 12.5 kHz systems? I'll have a talk about the Asterisk/app_rpt system in two weeks at a conference in germany.
