The following is a longshot.
One of my Tecsun PL-320 #radios seems to be in a half-dead state. The clock and other off-state functions will work when the receiver is off. But it won't turn on for actual #radio reception. When I press the power button, the screen goes blank for half a second, the backlight turns on, and then the screen switches back to the off-state clock display. I can set the clock and it is keeping time. However, occasionally, when I try to turn the radio on, the clock resets to zero hours and zero minutes.
I've been looking for some way to reset the radio to the factory defaults in hopes that the radio will function again. I've taken the battery out for the better part of the day but that didn't work. I put in a different BL-5C battery. That didn't work. As was suggested in one online post for the similar PL-330, I held down the "return" button, used to delete all memory settings. The device apparently did delete the presets, but still did not reset the radio.
I've found no reset button or receptacle on the unit. I pulled off the tuning and volume knobs to see if any reset button/hole was hiding behind them. Nope. There's also no such thing in the battery compartment, or behind the little stand on the rear of the unit. None of the so-called hidden functions on the PL-320 appear relevant. I pressed "VM" to get a display of the firmware version. That display appeared, but the radio still won't work.
I also can't tell if the radio will charge or not. The usual "CHA" indication on the display doesn't appear.
Given less than steady hands, I would rather not disassemble the radio but that would seem to be the next step. Before I take that drastic measure, does anyone have any ideas? I know the PL-320 is less common than the PL-330, but I believe they have much in common other than that the PL-320 doesn't have SSB.
Thanks for any insights you might have to offer.
