Build An Inexpensive Repeater
Controller
from a Basic Stamp 1 or 2
By Roger Cameron "NØYOX"
Basic Concept:
Everyone who builds a repeater needs some form
of a controller. There are many variations available. Costs range
from a few dollars for the very simple COR controllers to several hundred
for the real fancy ones. The project presented here will allow you to build
an inexpensive controller that will allow customized programming so you
can set up how you want the controller to function. How? Consider the Basic
Stamp. The Basic Stamp is a small microcontroller with on board memory
made by Parallax Inc., as well as some other manufacturers. Basic Stamp
version 1 has 8 I/O lines, and version 2 has 16 I/O's, I/O stands
for input / output. With a Stamp, your home PC, and just a few inexpensive
parts you can be on the air. The Stamp microcontroller runs a programming
language called PBasic which is similar to the Basic language. If you have
ever written in Basic you will find it very easy to program the Stamp in
PBasic. The manual and editing program are available free from the
Parallax web site, and the
programming cable is easy to build. If you have never worked with the
Basic Stamp before, you should consider buying the complete start-up kit
that Parallax offers. The kit includes a manual, a carrier board, editor
software, and cable to allow programming the Stamp from your PC.
Once the program is uploaded to the Stamp, it is a stand alone unit.
You can upload to the Stamp as many times as you like. Included here is
the programming code for the Stamp controllers. Features include
CW Id, Time out timer, Courtesy tone, and Repeater fan control. If you
