To Whom It May Concern,
I am trying to get a DMK URIx working with a BridgeCOM repeater using the usbradio.conf to provide CTCSS decode/encode and am having no success.
I can confirm that a received FM signals get repeated, and the allstar configuration also appears to be working. However any configuration related to CTCSS does not work at all.
I can confirm that the CTCSS tone is present with the input audio being fed to the URIx, but none of the relevant settings in usbradio.conf(e.g. rxctcssfreqs, ctcssfrom = dsp) seem to have any effect.
Adjusting the carrierfrom parameter in usbradio.conf has the expected results. The COR signal comes to the URIx from the repeater and functions correctly with carrierfrom set to usbinvert. At least with this I can confirm that apt_rpt is using usbradio.conf rather than simpleusb.conf.
While I have tested the hardware, I have not tried looking at the software beyond glancing through the source code to get a rough idea of the layout of apt_rpt.
Could anyone offer a working configuration example on CTCSS, or perhaps give debugging hints?
I can handle a debugger but am not sure of a good way to debug a program that operates on signals in real time.
Thanks in advance,
Neil
