CB - Computer Interface System

Use your computer to control your CB!

Imagine the possibilities that would open up if you could interface a computer with the channel control circuit (PLL chip) and transmit control of a CB radio. Memory capability, full use of any expanded frequency available in the radio, creative transmit control, not to mention the educational value of seeing binary and decimal data conversions in real time. Such a system would give you the capabilities and features found only in much more expensive radios.

The system described here can be used with any standard PLL-controlled CB to achieve all of those advanced features, and more. The best thing is that the actual electronics are amazingly simple, and can be built by anyone with a bit of electronic project construction skill. I have personally used this system with a Uniden PC 66, Uniden PC68, Cobra 148GTL, GE 5813B, Uniden Grant XL, Cobra 21XLR, and a Galaxy DX959. It can be adapted to many, many more radios, as well!

Up for Auction...

This auction is for the schematics and software for a system that will allow you to use any computer that is equipped with a standard parallel printer port (LPT1, LPT2 or LPT3 addressed port), and is running Windows-95 (or higher), to control your CB. The auction includes the following:

• Interface software
  • Application files
  • Application help files
  • All currently-available radio data files
  • PLL data test utility
  • Full instructions for creating your own data files
• Schematics for two different versions of the interface electronics
  • 7407 IC version
    • IC version comes with complete PCB layout for use with software available from www.expresspcb.com
  • Discrete transistor version: Can be built for practically no cost out of junk box parts!!

Here are a few of the features offered by the software:

1. Any CB will have split-frequency operation
2. Any CB will have 10 memory combinations available:
   1. Each of the 10 combinations contains a RX-TX channel combo and a separate RX-TX frequency combo
3. Any CB can be locked in transmit mode for testing purposes
4. Program remembers all settings when exited properly

Shipping is your choice of email file delivery (FREE), or a CD-Rom. If you choose the CD, shipping is a flat $5.00 within the United States.

International CD shipping is available for a flat $15.00 fee.
