Flex 6500, SSDR 184.108.40.206.
I have been running the system for 8 days straight monitoring multiple slices in WSPR and OPERA on MF.
1. PTT and transmit is occasionally activated for about a second or so with no modulation, seemingly at random. Digital PTT is disabled in their settings.
2 After 8 days I found that SSDR had lost connection and the 6500 was locked up, with a buzzing in the speakers. I had to hold the switch for 10s to force a shutdown and reboot.
I have only had this once with a long uptime so it mayt be hard to reproduce.
Not a big problem for a home station but maybe for remote installations in the future.
