the inexpensive soldering irons I have used successfully for years, no longer get hot enough to cause the solder to melt and flow.
Hello Tony,
I wonder if you have changed the type of solder?
I still use the "hazardous" lead/tin, the later lead-free is not nice to use.
Otherwise maybe someone could recommend a temperature-controlled iron?
I hope you find a solution, you are still providing good SDRs.
