I have been listening to solder smoke as soon as I found it on I tunes. I know I have been an appliance operator my ham life thus far but I looked at the video for the making of pizo electric crystals on the blog and with the ep 132 I was wondering If i can get a copy of he article from Italy to see the different mixes for different frequency responses sent to nccooling@live.com.
