Question about Sangean ATS 808A AM/FM/SW Radio

1 Answer

Sangean ATS-803A - no audio

The front panel appears to work fine except for the audio controls (vol, balance, base, & treble), The clock works. No audio on the speaker or phone jack. One can tune on all bands and see the signal strength meter respond to stations you tune to. However the signal strength and stereo indicator does not respond on FM band.

Replaced with new batteries and reset the processor by dropping power did not help.

I am thinking it might be the FM MPX & preamp ICs. Any ideas?

If its not a micro-p glitch, sounds like the radio was subject to a spike or surge wile plugged into the AC adapter. If the "power" light stays on all the time, thats what happened. Believe me, I was Sangean America's tech from 1990-1995.

The fix is to replace a transistor, or fet in the main pwr supply. (Close to where the adaptor plugs in.)
I wish I could give more details, but its been 14 long, long years.

Sangean PR-D3L - How do I change between 12 and 24


Archer, I have read the entire PR-3DL manual and there appears no mention of a 12/24 hr setting, unlike certain other Sangean radios. The instructions for setting the alarm do not mention 'a.m.' or 'p.m.' .

Apparently, the clock is a 24:XX:XX display only.

Sangean ATS 803A


Don't be mis-led by the working display. I had the "no power" problem with a working display too. I measured the voltage of the two AA batteries. One was 1.33 volts and the other was only 0.76 volts. Replaced the weak AA and everything worked. I suspect the 'enable' circuitry fails around/below 2.1v.
