Shut down problem with 6300
Comments

The only other device connected to the power supply is a small 12 volt relay that keys the amplifier. I don't think that is the problem as the radio has never shut down when being keyed. Only shut down in the receive mode. Thanks very much for your inputs.

Tim:
I do have a small 12 volt relay that triggers the amplifier powered by the same power supply as the radio - nothing else. I doubt that is the problem as the radio never shuts down when the transmitter is keyed - only shuts down in receive mode. The radio does not go through a wireless router. It is connected directly to the computer by the ethernet cable. However, a wireless router does come into play if I use the computer to open QRZ.com or check email while operating. I am wondering if that could have something to do with this problem. I am going to disconnect the computer from the wireless router as a test. Since shutdowns are now infrequent it may take quite a while to test this theory. I am still confused on how a loss in connectivity between the radio and the computer can cause the radio to power off. Thanks for your inputs. I'll let you know if I figure anything out. I suspect others must also run into this problem.

Can you scope the power supply output to see if there are any glitches? Perhaps strapping big electrolytics across the output to see if that solves the problem?0

Roger,
You mentioned a relay connected to your primary 13.8 Vdc supply and this got my attention...
Do you have a flyback (snubber) diode across the relay coil? If not, I suspect this may be your cause for radio shutdown. I have seen delayed issues where equipment running processors have been glitched an ultimately crash at a later point in time.
Should you not be familiar with this type of protection and the serious damage that could result, please review the following video.

Ist this solved? I have the problem that my 6300 is shut down inside a second. No blinking LED like normal power off procedure. It happen when I use more than 5 Watt TX. When is more than 5 Watt after 3 times TX RX für some seconds Windows is freezing. 6300 is off. PC need some seconds to recognise. I startet a request to Flexradio on Sunday and wait for replay. And I have ordered Ferrit for the cables. It was running with my ACOM 1010 around 500 Watt at loop and with out amplifier with 5 Watt this problem. Is yours now running? 73 Peter DD2MT0
