Shut down problem with 6300

My 6300 abruptly shuts down and powers off. Only happens in receive - never transmit. It happens with two different computers. One windows 7- the other windows 10. The windows firewall is off on both. I am using Smart SDR 1.9.13     Any ideas?

    Do you have a different power supply you can try? Also, disassemble and check the power pole connectors. Make sure the crimps are good and solder them if iyou have the ability. Report back if this doesn't fix the problem. 73, Mack W4AX Alpha Tester

    How are you powering the Flex? Only time I have seen this type of rapid shutdown has been power supply issue. Ian

    In my experience three things cause the radio to shut down. 1. Power interruption 2. Internal software error 3. RF ingress I've had 3 happen a few times due to common mode currents. Fixed that and didn't have it again. I've had 1 happen as well due to my own operator error (short circuit connecting an attached station accessory). Those are some things to check.

    Are the fans noisy? Over temp issues?

    Thanks Keith.  Fans are running but not noisy,  I can't find any shorts.  This has been an ongoing problem that I thought I had fixed by turning off the windows firewall but the problem has reappeared.  Thanks for your comments.

    I have not had any power interruptions.  Points 2 and 3 are possibilities.  I have reloaded the software several times to try and rule out software.  Regarding RF, this always happens when in RX mode.  It has never happened when the TX is keyed so I don't think it is RF but I do wonder if that is possible.  Thanks for your comments.

    Thanks Mack.  I'll give this a try and let you know.

    Can you see what the temp of the radio is? You can get this from DDUtil. Just to rule out any temperature issues.

    I don't think Windows firewall would cause the radio to shut down. It could cause disconnects from SmartSDR but not a total shutdown. 

    I think if all of that yields no fruit, you may just open a ticket with Flex and have them look at it to see if it's a hardware issue, assuming you're still under warranty.

    Hi Ria:

    you tell me where to find DDUtil?  I can't seem to locate that.

    Questions:

    Does it shut down orderly, that is does the power light start blinking and then power off (orderly) or does it just go dark and never blink (lose of power)?

    Has this just started happening with 1.9.13 or is this an on going thing?
  • ROGERROGER Member

    It just goes dark - not preceded by blinking light.  I never had the problem with 1.8.4.  It first appeared with 1.9.13.

    How do feel about regressing to 1.8.4 for about a week? This would help to eliminate a hardware issue. 

    How often does it happen by the way? 
    Do you leave your radio on all the time?
  • ROGERROGER Member

    That is probably a good idea.  I actually sent the radio back to Flex since they could not resolve the problem by email.  They said the radio is fine.  After disabling the windows firewall the problem disappeared for about a month and just reappeared 3 days ago.  It happened 3 times yesterday morning and then the radio ran for 13 hours with no interruptions.  It then happened 3 times this morning.  I need to head out for a while now but will leave the radio on.  I don't think this is RF related since it never happens when the key is down - only happens in receive.  Thanks for your comments.  I;ll see if it is still running when I return.  I'll let you know.  Thanks again.

    Roger, Respectfully, this is almost ALWAYS a power supply problem. Have you tried a different power supply? I suggested this early this morning. Mack
  • RiaRia Member ✭✭

    Also the cables should be secured. I use ring terminals which I crimped and soldered.

    Mack,

    I tend to agree. But it doesn't hurt to try 1.8.4. 
  • ROGERROGER Member
    edited January 2017
    You may very well be right.  i will need to get another power supply to check that out.
  • ROGERROGER Member
    edited January 2017
    That is my next move.  Thanks so much for your help.

    That would generate a issue specific error message.

    If that does not provide any remedy, I'd recommend opening a HelpDesk ticket.  I do not think this is software related based on your problem description.

    Hi Tim:

    Thanks for your interest.  I have been struggling with this issue for quite a while.  The radio was sent back to Flex on 11/18/16 under RMA15977 after spending a few weeks trying to resolve the problem.  It ran in the Flex repair shop for several days. It did not shut down and was returned to me on 12/13/16 after passing all production tests.  The shutdowns did not reoccur until 1/15/17 and continued on 1/16 and 1/17.  Shutdowns did not occur on 1/18 or 1/19 and the radio was running all day.  When the radio goes dead the green power light just disappears, it does not flash several times as it does when I am turning the radio off.  The power supply light remains on.  I have looked for any questionable connections numerous times and can not find any.  When the shutdowns occur an error message appears saying that the connection to the radio has been lost.  This always happens in the receive mode - never when transmitting,  Therefore, I don't think this can be RF related.

    When I am turning the radio off, I always exit the software, turn off the radio and wait for the green power light to go dark before shutting off the power supply.  I decided to see what would happen if I turned off the power supply without first exiting the software and turning off the radio.  It behaves exactly as it does when abruptly shutting down.  The green power light goes off without first flashing several times.  This leaves me wondering if the problem could be caused by very brief interruptions in the power supply that do not cause the power supply to actually turn off.  The power supply is the 25 AMP Astron that I bought from Flex in September when I bought the radio.  Unfortunately, I don't have a spare so I may have to buy one to test this theory.  This is very perplexing.  Any help you can provide will be most appreciated.

    If you don't have another 12V power supply then do you have a 12v battery you can place in parallel with the power leads. That would also eliminate a power supply issue. Mack

    something you may want to try, take a **** drive and gentle hit the power supply and or the radio with the handle end. If you have a intermittent connection, it might show up. Old TV repairman trick.

    I have noticed that when using several devices on a power supply common to the Flex that even the slightest short will shut down the radio. It can be so quick as to not even trip the power supply however the radio will shut down.
  • Tim - W4TMETim - W4TME Administrator, FlexRadio Employee admin

    And that is a good thing.  The radio is protecting itself from what would end up being a non-warranty repair.

    Not sure how such a momentary duration short external to the radio so quick as to not trip the power supply would damage it...however I'm not complaining just observed it.
