(1) We wanted to stretch your battery budget: with the LED drawing
about 6 ma, how long will your battery last if you leave your receiver on
for a few days, just like we leave our computers and Ham or computer
accessories on all the time?
(2) We thought you'd have more fun planning and installing your own
lamp that glows in the dark!
(3) We could not decide which color you would like best!
THE RAMSEY ELECTRONICS CASE, KNOB & HARDWARE
OPTION
Your finished receiver can be installed in a variety of enclosures of your
own design and choosing. You might be planning to combine several
Ramsey circuit boards in a single enclosure. Use of the inexpensive
and attractive Ramsey case and knob kit will give your unit that finished
look and increase its resale value. These sturdy black instrument cases
are supplied with neatly-lettered front and rear panels, knobs, rubber
feet and mounting screws.
OTHER ENCLOSURE RECOMMENDATIONS
While we believe that the Ramsey enclosure and knob option is a fine
value for finishing off your Ramsey receiver or transmitter, we are happy
to give you a couple of additional suggestions. If your first goal is
economy and rugged portability, you will find that the circuit board can
be mounted nicely in a standard VHS videotape storage box, which also
gives room for a speaker, or earphone storage, and even a roll of
antenna wire. The controls are easily mounted at one end of such a box.
It may be necessary to cut away the molded posts which secure the
tape cassette itself. These storage boxes come in several styles, so pick
one that looks truly practical as a project enclosure.
To accomplish RF shielding, the most economical metal enclosure
nicely suited for Ramsey amateur kit boards is Radio Shack No. 270-
253A. This metal utility cabinet can accommodate both a receiver and
transmitter board, plus speaker, with room for various refinements you
might like to add.
