night my Flex-6600 started rebooting itself. About every 60 seconds to a couple of minutes. I thought it might be computer related so I disconnected the ethernet cable, disabled remote on and removed its physical connection. The radio is in the following state. I turn on the power supply, turn on the radio, it boots, and the green light comes on. It then crashes and the light blinks red until I turn off the power supply. It does not matter if the radio is connected to the computer, switch or router, or stand alone. It does the same. I have done a full uninstall according Flex procedures and started over. It was in vain. I have attached a link to a video, at 2:31 in the video it crashes. In the video the 6600 is not connected to the computer, it is completely stand alone. I have left the radio on since I received it a few weeks ago for infant mortality purposes.

per the hardware manual (see below)
the single flashing red mean FAN Malfunction detected
my guess is it came unplugged
as the saying goes
"open a help desk ticket, they can walk you thru the process"
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.
Thanks for the help guys. Dan
I do realize this is a support forum and you are more likely to hear problems than praise. But I have ordered a 6600 and I am nervous as I hope the radio is as stable as my 6500 has been.
With Tim out and recoverying with his bad wing, Dudley has been a bit busy, but he will get back to you. And, the phones are ringing off the hook. Litterly. I took over 60 calls yesterday personally, so if you do call don't be surprises if I push to keep the call short. Leaving a message will get you call back. Try to leave some details of what you need with your message so we can do some homework before we call you back.
However, many of you do love to share your life history with me. :)
I am happy to report my 6600 is back and working just fine. To follow up, Flex emailed me a UPS ground label on Tuesday the 13th. I shipped the radio on the 14th. The radio arrived at Flex on the 20th. They contacted me on the 23rd and asked for a shipping address to return the radio back to me and shipped it that day. I asked them to overnight it. They did not however, they did send it 2nd day. I received it back on the 27th. They replaced the faulty fan. It is very nice to have it back. What I would have like to have seen is overnight shipping both ways. When a radio fails right of the box as this one did, the response time should be quick, including transit times. Anyway, near the end of this saga, Flex asked me to complete a survey of my experience. I informed them of this area so they can plan for improvement. For performance I give them a B. Overall I am satisfied with their products. This was my 3rd radio purchase from Flex. Thank you all for your input.73, Dan KM6CQ
It went to FRS fine, came back this way. So hopefully there is a cable getting to the fan but we will see. Help desk ticket is open.
The fan when started sounds like a coffee grinder and even after a factory reset the radio shuts down after 60 seconds all the time.
So I've updated the help ticket and we will see what FRS wants to do.
Just a note for future design FRS... I think you should make the fans field replaceable. It seems that there have been quite a few fan failures in the 63/5/700 line and now in the 64/600 line.
sorry about your fan. It is frustrating. They replaced mine with the same make and model. If it fails again I will install a Noctua. I use them on my builds and like them a lot. Of course your probably already ahead of me on that. When I spoke with Gerald at the Visalia DX convention, he thought it was the bearing that failed in fan. He said it was sitting on his desk and he still needed to open it up and look. I sent my 6600 back a few weeks ago for the pen update. UPS says it will be here today. I fall back on the 7300 but I 6600 is my go to rig. Been playing with FT8CALL lately. It has been fun, although there are only a few of us on the air at any given time. Good luck with outcome of your rig. We all know Flex takes care of their customers.
Tim contacted me today. He said they need the radio back, it may be a fan controller issue. He said a fan failing twice in the same radio is extremely rare. I attached a video of the fan noise for you to view. I also attached a video of 6 meters. My TX display on 6 meters has always jittered no matter what mode I use. For the video I ran low power CW into a dummy load. Have you ever used your rig on 6 meters and noticed this?

I think it is just an artifact. I think the TX display is ball park but was never meant to be accurate. More like a bonus they gave us, some good information is better then now information at all I believe was the thinking. I have made 100's of 6 meter FT8 contacts without issue.
