I found many boards with C1,2,3 in B40 with bad solder and no continuity. This was in earlier batches.

Start at C3 and work back towards C1 for RX. Check for coil continuity and scrape and resolder the wire if required. Raj At 22-12-2017, you wrote:
Ok guys...I've gone through the video. I've removed the squeal from my receiver. The first coil there was shorting... (the one where you put the capacitor on the underside) so the entire board was getting nothing. Unfortunately, the last coil in the bandpass filter is not working....c1 doesn't produce any sound. THAT is going to require me to take the thing apart....take it out of the lunchbox. BUT, according to the video, once I do that, the receiver will be working. That's a job for tomorrow night though. |
