Don’t Disturb the Dust!

Filed under: Electronics,ham radio — Cranky Sysadmin @ 11:39 am

My Heathkit® project took a turn for the worse yesterday. There was some occasional arcing in the audio section when I turned on the radio. The cause seemed to be the sediment on the board. Do you know that feeling you get when you’re about to do something bad? Yeah, I’ve discussed this before, and I ignored that feeling again. Instead of taking the safe and lazy route of tracing down where the arcing was coming from, I decided now was a good time to lift the audio board out and clean it up. As the dear reader might predict, the audio section is now non-functional. I’m pretty sure things are wired up correctly. My current suspicion after triple-checking the wiring is that I disturbed some marginal component enough to stop it from working. I’ll have to look at after I complete some other easy projects that have been languishing, like my solar charging station and short vertical antenna.
