[Repeater-Builder] Source of Coil Slugs
I'm trying to modify a commercial boat anchor from 42 - 50 Mc. up to the 6 meter ham band. Not even one coil in the RF preselector and 1st oscillator/multiplier chain will tune into the ham band, which is very unusual for this radio. There are just too many tuned circuits to consider removing coil windings or changing capacitors so I want to try using brass or aluminum coil slugs in place of the powdered iron ones now used. Does anyone know of a source for these slugs? I can mic. the slug diameter and guestimate the thread pitch if anyone has any suggestions. TIA for any/all help. Tom DGN

What model of radio are you working with here? -- Original Message -- Received: Tue, 15 Dec 2009 08:47:06 PM PST From: wb6dgn tallins...@yahoo.com To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Source of Coil Slugs I'm trying to modify a commercial boat anchor from 42 - 50 Mc. up to the 6 meter ham band.

Tom, If you identify the make and model of the radio, perhaps someone who has gone this route before can comment. Otherwise, carefully remove one of the slugs and take it to a good hardware store where you can use a thread gauge to identify the thread diameter and pitch. With luck, that store may have machine screws in brass and aluminum that can be trimmed to make the proper slugs. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of wb6dgn Sent: Tuesday, December 15, 2009 8:46 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Source of Coil Slugs I'm trying to modify a commercial boat anchor from 42 - 50 Mc. up to the 6 meter ham band.
