TRY BUILDING AN [EXTERNAL] ANTENNA "GIZMOE" CONNECTOR BOX: Most Shortwave Radios can benefit from one of these little External Antenna "GIZMOE" Connector Boxs http://groups.yahoo.com/group/Shortw...enna/message/7 GIZMOE BOX's Antenna Input Connector Plug or Two Terminals: [ Metal {Plastic} Utility Box ] - One for the Antenna Connection. - The 'other' for the Ground Connection. + Solid Heavy Duty Hardware for Grounding Point. A = Antenna Connection Point G = Ground Connection Point {& Plug/Terminal} * = Space {Blank Space Indicated} R = Radio/Receiver Connection {Plug/Terminal} NOTE: Diodes 1N914, 1N4148, ETC.

Can use a short piece of Coax Cable or a set of short wires between the Gizmoe Box and the Radio/Receiver with the proper Plug/Terminals on the end. Hope this helps ~ RHF I like the neon tube and bleed resistor idea. They cost next to nothing and really help. mike |
