Re: Bitx40 with Raduino stopped working #bitx40help #bitx40

 

If your very sure which pins are what on the regulator, which should be fairly easy to determine, then cut the output. Now, the output should have a capacitor across it to be stable, but, for a quick measurement, you should show 5 v if working. Its on the other side of the regulator from the 12v input and has a 1uf cap to ground on it, which is on the board. I think it would work ok without the cap and give you 5v.?

Also check that your ground connection to the Raduino is correct.

If your GND to the Raduino is OK, but you're still getting only 0.04V out
of the regulator, then
- either the regulator output is somehow shorted. Inspect the Raduino
board, check for any shorts, check capacitor C3 (1 uF).
- or the regulator is defective (replace it)
