Re: Technika 206 DAB radio NO AUDIO

2 things i notice about dab,

1: they all look like shit - like some tacky 50's look.
2: there are a hell of a lot of fault reports online.

i would scope the input and output of the dac.

It may well come to that but currently don't own a scope so for now shall continue troubleshooting back to the dac where possible. Fun learning on the way!

If it is the dac it'll be going in the bin anyway as it doesnt look repairable.

Ok, so getting audio through the LM324 via the caps on the PCM1742 VoutL and VoutR traces.

Not quite sure how to progress with this now so have bought another identical working unit to swap the Radioscape DSP over to prove thats the fault which I highly suspected from the start.
Shall report back with my findings in a couple of days.

At least I'll have a working radio back in my workshop again, hopefully!

So swapped out the Radioscape RS220 with a known working one and still no change so the fault is definately on the power/amp board.

Also changed out the control/button keypad and the headphone jack pcb with no change.
