Joni,

I used platinum/iridium alloy wire, but nichrome can be used too. The gauge isn't too critical, thicker is better mechanically, 16-22 gauge is quite suitable.

I just read your nichrome wire test http://www.vk2zay.net/article/73.

I'd like to know what gauge you used for the nichrome wire.

Thank You,

Joni
