A SHORTWAVE RADIO FOR UNDER $5??? YOU GOTTA BE KIDDING!!!
-----------------------------------------------------------------------------
Yes, you can construct a decent shortwave receiver for a total expenditure of
less than $5.00, with a little luck and a halfway decently stocked "junk box"
of components. Here's how it can be done.

Refer to the enclosed files CONVERT.TXT and AMRADIO.TXT. They describe how
to build a shortwave converter, and then install it into just about any old
AM table radio or clock radio. Unlike the car radio installation, you will
need no external power supply or speaker, saving you more than half the
expense of components. The capacitors needed for the converter are common
types, and likely scavengeable from your own parts box or available for only
pennies each at a Ham show. Likewise, the miscellaneous parts, connectors,
IC socket, wire, etc. The NE602 IC would cost you about $2 at the same Ham
show, if you can find someone selling them (they are becoming more easily
available all the time). A green IF transformer for the converter could be
had for $0.50 - $1.00, or maybe you could (carefully) salvage one from an
old transistor radio PC board if you had specialized desoldering equipment
and a skilled hand. A 5.1 or 6.2v zener diode should be no problem, costing
you maybe another quarter if you needed to buy one. Frequency crystals can
be had for as little as $.25 - $.50 each, with some judicious shopping, and
only one is needed to start. If you need to buy EVERY component for the
converter at a Ham show, you could still squeeze under the $5 barrier.
Maybe.

If you can't make it to a Ham show, or can't find all you need there, well
then order it by mail from DC Electronics or some equally good supplier (see
READ.ME file), where you will have to pay an extra $3.50 or so shipping/
handling charge, bringing your total cost within spittin' distance of $10.
Sorry about that. That would mean you'd have to save an extra week's
allowance before you could enjoy shortwave.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
