[Amps] Pulser

[SavanaPics at aol.com]

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

Hi  Ed,

Thats what I do, tune up on CW and use the keyer.  High speed  dits do the 
trick.
