My Flex 6500 with Maestro unexpectedly quit passing audio through to the speakers when on the 6 meter band. I have had the Maestro for approximately 2 weeks and all has been working well until now. I have no audio when I select the 6 Meter band on either Slice A or B on either Smart SDR Version 1.7.30 or the Maestro. I can chose any other band in either of these slices and get full adjustable audio, but when I select 6 Meters, no audio. I can see signals in the waterfall. I have rebooted the Flex 6500 several times along with the SDR Computer and the Maestro, but still no 6 Meter audio.
