Flex 6500 error message check fuse

While transmitting on my Flex 6500 I received the following error message: Error PSL_13B8B – 09.46 check fuse. The receive side of the radio is fine but obviously the transmit side is out.

How do I change the fuse for the transmit side of the radio?

I am using a QJE power supply model number PS 30 SW 1V. It should be plenty for the radio, any comments?

Thank you in advance for your help

G'day Bill,
I have found that CW at 100w can make this happen a few times.
My PSU may sag at 25A or possibly RF getting in to it.
Turning the radio off has fixed it so far.

The fuse is not blown. That error indicates that your input voltage after the internal fuse dropped below 9.5VDC. If the fuse was blown, the radio would not power on. Check your power supply and the DC cabling.

Bill,
I had a similar problem and it turned out to be a Astron 30 amp power supply voltage regulator failure.

Andrew and Tim,

Thank you for your prompt reply and good advice. A factory reset of the radio resolved the issue. I checked all the connectors and everything seems to be okay. I am suspicious that the QJE power supply might be the issue although I can't confirm it. I am moving a 30 amp Astron supply over to handle the radio. This should resolve any potential QJE issues. Thank you again for your help.
