Larry, a fellow HAM in the Atlanta area makes a device called the PECKER.
it was a big hit years ago on the 3898 group and is still quite popular (
not to mention reasonable) it is available in either assembled or kit
format. Go to _www.mrpecker.com_ (http://www.mrpecker.com) . If it is for an
Icom, be sure to ask about the 100 mfd non polarized electrolytic
