My 6600M is doing the same thing.  With SDR or with the radio alone.  The radio then reboots and then I can reconnect.  It has done it twice while I was transmitting and once or twice a day in receive only. Running .33

in the flex manual are the power button flash code

Power Button Color Codes

The Power button is used to turn the radio on and off and is illuminated with a number of colors to indicate the radio’s operational state:

  • FLASHING GREEN: Radio is starting or shutting down

  • SOLID GREEN: Radio is in receive mode

  • FLASHING RED: See Error Conditions below

  • SOLID BRIGHT RED: Transmitting on PA

  • SOLID DIM RED: Transmit engaged, but transmit interlocks are not ready. Refer to the SmartSDR documentation for description of the transmit interlocks.

  • SOLID ORANGE: Transmitting on XVTR port with low power

  • SOLID PURPLE: Radio is performing a software update

  • FLASHING WHITE: Radio is performing a reset to factory defaults

  • OFF: Radio is off

Error Conditions
  • Certain hardware and software error conditions cause the radio to stop operating and display an error code by flashing the Power button light as follows:

  • One red flash: Fan malfunction

  • Two red flashes: Software crash

  • Three red flashes: Boot failure

  • Four red flashes: Input power over voltage

  • Five red flashes: CPU overcurrent

  • Six red flashes: Input power under voltage

    In the case of a software crash, the error code repeats for about 15 seconds, then the radio will reboot.

  •  In the other cases, the error code repeats until the Power button is pressed, then the radio shuts down. An additional press of the Power button is needed to restart the radio.

  • Avoid removing power from the radio when it is performing a software update (power button is solid purple). Doing so may result in the radio becoming unresponsive.

Similar issue but was rf apparently via the Ethernet. Cable. Grounding the computer to the single point ground and four clamp on cores on the cable fixed it. This happened on the 30 and 20 meter band, one or the other. RF does strange things.

My 6400 is 3 months old and it has done the one red flash fan failure twice. The radio was just sitting idle in the receive mode. Hard to believe it's a fan failure with the error 2 months apart. Software glitch?

My 6400M flashes red twice 100% of the time if I run more than 80 watts and don't engage the ATU. It is not RFI as if I use 20 watts and engage a 700 watt amplifier no problem. It also does it on a dummy load. Tim tried extensively to solve it, but failed. I just engage the ATU.

I assume they offered to replace/repair the radio?

No but it still has 18 months to go on the warranty.

This is not normal operation of the radio. It seems strange that Flex can or will not help you past what Tim did.

I haven't pushed them. There is no rush as long as I engage the ATU no issue. If it isn't fixed as the warranty runs out I will push it.

Happening a lot on the new 64/6600 boxes, but not being reported on the older boxes. Suggests some kind of newly designed problem.

It is likely a software glitch. There are hardware differences between the older 6xxx to the new radios. When Flex makes changes in software it needs to work the same on all radios but certain code is directed to a spacific model. That is why testing can take longer. All 6xxx modles need testing.

I think the problem is undervoltage.
That after this error the Flex6600 flashes 2x red (software crash) is misleading.

I also work without antenna tuner because I use a smart tuner on the antenna. If the SWR is greater than 1:1.5, the PA draws more power and my power supply (Max 22 Amp) quickly reduces the output voltage. The multimeter may display 12 volts, but the RIGrunner PowerPole splitter bar beeps and shows undervoltage.
In the upper bands, the error is faster, even at the dummy load. At 10 m tape my dummy load SWR brings about 1: 1.5 - here helps ATU of Flex ..

I then tested with a stable power supply. The voltage drops not less than 13.5 volts even at 100 watts and the error does not occur.

My Flex 6600M would not completely boot this morning when I turned it on.  Instead of completing the boot process, it shut down with a series of single red flashes of the power light which means that there has been a fan failure.  
I could not hear the fan running.  Before taking the radio out of mounting rack, I decided to disconnect the power plug for 30 seconds and then rebooted the radio.  This time the fan was running and it booted all the way up normally.  Has anyone else seen this same behavior?
Should I be concerned with an impending fan failure?

Yes you should expect a total fan failure.

Can you please tell me more about your fan failure?

I just had them on 6300 and 6700s. They would start just like this. Fan won’t start on boot, but reboot it 5 times or tap the radio case and something jars it to start. Once its going it goes for days or weeks usually before the radio would freeze or die due to fan failure but usually you could start it up again with enough tries. You could limp along for months usually like this. I’m terribly sorry to hear about this, but in my experience flex support will waste no time in making it right if that makes you feel any better.

OK Matt, Thanks for the details on your 6300 and 6700 fan failures.  That is a known problem on those models.  I friend of mine just had a fan failure on his 6700 and apparently the fan is bonded to the FPGA so it had to go back to Flex.   They turned it around quickly and got it back to him repaired within a week.   My Flex is a 6600M which has one, large, fan that is not bonded to the FPGA or CPU.  My fan failure "red light" indication has only happened once.  A simple reboot did not fix it, but after I disconnected the power connector for a minute and then rebooted, it came back on normally.   It is strange that only a completer power down seems to fix the problem.  I have turned the radio off and then rebooted it many times since with no problem, so we'll see if the fan does actually fail in time.  73, Geoff
