Newradio.zip contains Pascal source code for a PC program that
controls the HF transceiver documented in QEX magazine in the 
following articles:

 "The ATR-2000: A Homemade, High-Peformance HF Transceiver, Pt 1",
 March/April 2000 QEX

 "The ATR-2000: A Homemade, High-Peformance HF Transceiver, Pt 2",
 May/June 2000 QEX

 "The ATR-2000: A Homemade, High-Peformance HF Transceiver, Pt 3",
 March/April 2001 QEX

The source code is written for Borland Pascal for Windows version 
7.0 and object and executable files are also included. It uses the 
standard Borland Pascal units for Windows 3.1 for I/O and CRT control.
The program present a text-oriented display within a window and 
commands are entered via single or multiple keystrokes. It requires 
the wcom.pas serial driver for compilation. Wcom.pas is public-
domain software that is available over the Internet. The executable
has been tested on Windows 95 and Windows 98 by the author with his
implementation of the transceiver. The files contained in the zip 
file are:

 newxcvr.pas	Transceiver control program source code
 newradio.pas	Unit containing supporting code for newxcvr.pas
 ddsctl.pas	Unit containing code to control DDS chips in xcvr
 radioinf.pas	Unit defining constant used by newxcvr
 convinfo.pas	Unit containing constants defining frequency ranges
 newradio.tpw	Unit containing supporting code for newxcvr.pas
 ddsctl.tpw	Unit containing code to control DDS chips in xcvr
 radioinf.tpw	Unit defining constant used by newxcvr
 convinfo.tpw	Unit containing constants defining frequency ranges
 newxcvr.exe	Executable tested on Windows 98

This program communicates with firmware in two PIC microprocessors 
embedded in the transceiver over a RS-232 link. Source code for this
firmware is available on the ARRL Web site. The program also makes use 
of a rotary shaft encoder for tuning. This device is also accessed via the 
common RS-232 link and is polled for differential position information.
