When I got my Novice ticket back in 1957.....(wow!)<br />It was good only for 12 months.<br />You could not renew...nor re-apply for the Novice class. You either upgraded by testing before FCC examiner or you were out. Don't know when they expanded to two years, but for me it was one year.<br />George Allgood<br />W4GFA<br />Walhalla, SCmyp4k69@bellsouth.methttps://www.blogger.com/profile/13579573554454790600noreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-1345177476184468402011-04-15T12:47:05.180-04:002011-04-15T12:47:05.180-04:00Who's going to be the first to construct this ...Who's going to be the first to construct this using stone knives and bear skins.

You could get a little DC motor, pot, neon and mirror for much less than that at any decent surplus store or even Radio Shack. But that now-precious variable cap in the tuned circuit had better be in your junk box. Can a low-power transmitter induce the 80-100V it takes to fire a neon?Mike - KC7ITnoreply@blogger.com
