Yaesu FT450 was stepping up in bands, suddenly at 18.09 started blinking w/sharp demands for current then immediately off back on etc. Repeated off then back on with same result. Can't get out of the loop.

Hi there,There may be a fault with the power supply circuitry - do you have schematics and test equipment available to diagnose the fault yourself?
Customer: replied 7 months ago.
Don't have the schematics ... do have 12V from the pwr supply. Have any suggestions.
Expert:  Pete replied 7 months ago.
Let me see if another expert has any ideas on this one...

Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, proposed preliminary tries (if have not been done) would be to press the TUNE switch to turn off the Automatic Antenna Tuner and try again if the high current issue would persist.All others would require the use of a multi-meter and a dummy load + wattmeter.
