John, I have worked for long time in an non iron metall laboratory. If copper is heated to glowing temperature, it will change it´s modification. What remains is some type of copper which will break later or earlier. Using a butane or propan torch you there is only a very small chance not to overheat the copper wire. In my QRPproject manuals, even in my translation of the Elecraft manuals, I warn to use this methode of burning away the enamel. 73 de Peter, DL2FI _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
