What could cause the Error: RX Input Adjust Failed? DONE tries=12, setting=1000, meas=58, sqnoise=13 ERROR: RX INPUT ADJUST FAILED. No RF input to the radio. I'm attempting to setup a substitute receiver for testing, but am experiencing difficulty setting it up, and not wanting to make a switch to simpleusb, thus making the minimum number of changes. The substitute receiver (Yaesu FT-1500M) is detecting CTCSS, with USB COR out, and I'm using the speaker output. (see below conf file) Any thoughts?
