6500 locking up in transmit/PSL error message

Tim...Is there a published list of these error codes so we can check them ourselves? That would be interesting.....(My guess is that many of them would be meaningless to most of us, but interesting nonetheless.)

Interesting, I ran into this same problem (low power supply error) this morning. thought I would add my findings. It was the first time powering up right after reconfiguring and rewiring my entire shack (radios, coax, Ethernet, audio cables and power supply cables, which runs to 3 different radios. I read this posting yesterday, so was prepared for what I saw this morning. However, In my case, the PS worked perfectly the day before (old layout) and the 6500 played well early AM at 100 w on several different bands. The problem did not show it self until I powered up the AMP on 40m. Even with 10w drive on 40m from the 6500, the error showed up. Since it did not show up on other bands like 20m, I'm going to better isolate the different cabling and check all coax connectors to make sure I did not leave one loose.
