Intermittent loss of comms with radio

Mal G3PDH

in FLEX-6000 Signature Series

Set up is Flex 6500, Maestro, Computer W10, Network switch connected to radio, computer and Maestro and linked back to Router.

I am experiencing intermittent loss of comms with radio.

In an effort to isolate the problem I have eliminated the network switch and separately tried connecting the radio directly to the computer and then to the Maestro using a different CAT cable each time. The fault happens under both options.

At some indeterminate interval, half an hour, an hour or more, I note the AF start to break up then the green light on the front of the radio begins to flash and my call sign entered in the window on the radio front panel goes out then reappears after which the green light continues to flash then become continuous as normal indicating the radio is ready for use again. The Maestro will freeze or change back to the starting screen showing the radio ready to reconnect. The computer seems to re-establish itself but shows an error message stating that the computer and radio have lost communication. it is impossible to send any proper CW however, just garbage.

From these tests the radio seems to be the common factor but would appreciate advice on any further tests, checks or front panel display readings that I can do to establish the cause.

    Hi Mal, I would submit a help desk ticket.

    Further to my earlier posting regarding loss of comms with the radio (6500)

    I have submitted a ticket.

    Have also carried out further checks. After losing comms between the radio and computer they both restore to normal operation on their own after about 1 min and continue to operate. All seems ok until the next time it randomly happens. I simultaneously monitored the supply voltage with 'Flex Meter' using the graph facility and there is no change in supply voltage during the period of losing comms.

    Hi Mal... from your description, it seems like the radio is going into a reset condition for some reason. Possibly RF feedback? ?? The Help Desk should be able to take you through more diagnostics to discover the source.

    Don, This happening in RX mode, no transmissions involved. Strangely, over 4 observed failures it seems to be happening at around 35 minutes intervals which is odd but probably just a coincidence. It happens with either the PC or Maestro connected directly to the radio. Anyway, will see what Flex have to suggest next week. radio/SSDR software version is 3.4.23 latest.

    The Link.Local test (single cable, nothing else) is a great test. Next steps is for our support team to debug this.

    Mike, Have carried out factory reset and seems to have fixed the problem. Reported this as support ticket update and will confirm in next few days if problem has completely gone.
