Hello all, We received our RTCM's this week, and I am working to interface them to the Quantar. I've run into a few issues: 1.) AUX TX Audio. I've had success with one machine in getting the audio out of Pin 5 of the Telco connector, but not on the other. Is creating a wildcard table to enable "AUXTX-TX ON" when there is an input on Pin 9 (PTT) the correct method to enable TX audio output on Pin 5? 1.) BEW Mode. My RTCM's show it as unavailable as an option to enable. Is there a trick to enabling it? 2.) I cannot seem to get the squelch calibrated. I get a slow flashing light a little while after I enable squelch cal, which seems to indicate low discriminator noise. I tried enabling jumper JP1 with no change. Does BEW mode need to be enabled to get a proper squelch calibration with the Quantar? Tim suggested that some older firmware version may not provide enough discriminator noise. I want to be sure I've exhausted all options before I hunt for SCM with newer firmware for these machines. Thanks, Caleb
