- * TECHNICAL PROGRAMS FOR THE BROADCAST ENGINEER *

-
- DISCLAIMER: These programs are provided without charge to interested
- broadcasters and may be copied. USER IS SOLELY RESPONSIBLE FOR THE USE,
- APPLICATION, AND RESULTS OF THESE PROGRAMS.
-
- These are technical programs for an IBM or MS-DOS compatible computer.
- All programs are in BASIC. You must load a version of Microsoft BASIC
- (GWBASIC, BASIC, or BASICA) from your version of DOS. It would be best to
- copy basic onto this disk. (The batch file TECH.BAT calls for GWBASIC).
-
- There are two ways to start the programs. From the DOS prompt ">": (1) Start
- GWBASIC or BASICA (for an IBM) then RUN "TECHMENU" or (2) Enter "TECH" to
- automatically load GWBASIC and run the TECHMENU.BAS program. The TECH.BAT
- batch file will start GWBASIC. If your version of BASIC is called "BASIC" or
- "BASICA", change the name of "GWBASIC" in the TECH.BAT file. For HERCULES
- GRAPHICS start the program with "TECH-H" instead of "TECH".

-
- To install these programs on a hard disk drive, put Disk in drive A:
-
- Type: md c:\tech Creates subdirectory called TECH.
-
- copy a:\*.* c:\tech Copies all disk files to TECH directory.
-
- The files KRAP and KXXX are sample data text for the FM OPERATING PARAMETERS
- program.
-
- * * * IMPORTANT NOTES FOR VERTICAL FM PATTERN PROGRAM * * *
- A. Your computer must have a graphics adaptor card to view the screen
- graphics of the VERTICAL FM PATTERN program. (The printer will still print
- the graphics with or without the graphics adaptor card).
-
- B. BASIC DOES NOT SUPPORT HERCULES GRAPHICS. The VERTICAL PATTERN
- program is compatible with the Hercules or Hercules compatible video graphics
- card by loading a CGA emulation program. If you have Hercules Graphics, try
- starting the programs by entering "TECH-H" instead of "TECH".
-
-
- * * * NOTES ABOUT PRINTER COMMAND CODES * * *
- Some of the programs have printer routines which may not be compatible with
- your printer: FM OPERATING PARAMETERS, COAXIAL CABLE RATINGS, FM POWER CHART,
- STL CALCULATIONS, and VERTICAL FM PATTERN. There is a menu for 4 types of
- printers: (1) Brothers or Diablo, (2) IBM QuietWriter, (3) Epson, (4) Tandy
- Daisywheel [untested] and (5) HP-Laserjet. The printer command codes are for
- the Brother HR-35 (Diablo Code). It's easy to change the printer command
- codes for other printers. The codes are defined in a few statements of the
- program. If you change the printer commands in the statements -- the whole
- program will run with your printer. If you need to change the command codes
- - try changing the (1) Brother/Diablo codes. The program lines to change are:
-
- FM.BAS LINE 240
- COAXPWR.BAS LINES 270 & 280
- CHART.BAS LINE 1090
- STL.BAS LINE 4690
- VERT-PAT.BAS LINE 2380
-
- ASCII CODES FOR HR-35 PRINTER used in programs
-
- 10 Pitch: 27 31 13 (10 Characters per inch)
- 12 Pitch: 27 31 11 (12 Characters per inch)
- 15 Pitch: 27 31 09 (15 Characters per inch)
- 6 LPI: 27 30 09 (6 Lines per inch)
- 8 LPI: 27 30 07 (8 Lines per inch)
- Bold: 27 87 (Double strike for bold)
- Bold Clr: 27 38
- Carr Rtrn: 13
- Line Feed: 10
- Back 1/2: 27 68 (Backup a half line)
- Form Feed: 12
- Reset: 27 13 80 (Reset printer commands to initial setup of 10
- pitch, 6 LPI, main ribbon, etc.)
-
- NOTES: The above numbers are enclosed in CHR$(nn) statements in the
- programs. Example: CHR$(27) is ESCAPE.
-
- nn denotes a number which must be inserted.
-
- If you have questions about changing the printer codes, need help running any
- of the programs, or find errors in the programs, call me.
