TIL: I started building my QMX+ transceiver but kept struggling getting the solder to flow properly. Tried flux paste which didn’t help. Started thinking “did I forget how to solder???”. Then wondered if my Hakko wasn’t working right.
Did some digging and discovered it has a temperature adjust feature leading me to think I might have entered an adjustment inadvertently. More digging and I discovered a secret but trivial method to reset the Hakko soldering station.
Voila the solder flowed…
