Oct 20, 2011 · If this is not possible then an good alternative is no.16 or no.18 enamel covered copper wire. If this is not available then standard no.18 speaker wire will suffice With one end of the wire connected to the disk, begin winding a consistent coil around the rod. The coils should sit next to each other and be bound tightly to the rod.

The larger radio is my Sangean ATS-803A shortwave receiver. The smaller radio in the foreground is a travel alarm/AM-FM radio from the late 1980s. I converted it to receive shortwave frequencies between 4 and 9 MHz and used it that way for a while. You can make a like conversion on an AM radio you own.
