- INTRODUCING THE RF SPECIALTIES
- TECHNICAL PROGRAMS DISK
- " R F S "
-
- This is version 1 of a new disk specifically designed for radio broadcast
- engineers. Bundled into one program are many different sub-programs
- of general use to the engineer. These will allow you to:
-
- * Calculate the E.R.P. of an FM station.
- * Display and print the vertical radiation pattern of an FM antenna.
- * Calculate the distance to the null of an FM antenna.
- * Calculate VSWR, or print a VSWR table.
- * Calculate path attenuation and fresnel zone clearance of a 950
- mHz S.T.L.
- * Calculate and print a report of intermodulation products between
- a table of frequencies.
- * Calculate the size of a parcel of land needed to hold a guyed tower
- of given dimensions, and place the tower within the plot.
- * Calculate the distance and bearing between two geographic coordin-
- ates, or calculate the destination coordinates when source
- coordinates and a distance and bearing are known.
- * Perform conversions from English to Metric units
-
- In addition, an Electronics Math program is included. It allows the user
- to work with:
-
- * Ohms Law calculations.
- * Series/parallel resistor, capacitor or inductor networks.
- * R/C or R/L time constants.
- * Series or Parallel L/C circuits, resonant or non-resonant.
- * Series resistor voltage dividers
- * Transformer voltage, current and impedance calculations.
- * Decibel conversions.
- * Frequency to wavelength conversions, in both English and Metric units.
-
- This program also includes information about the RF Specialties Group and
- its six offices around the country. The RF Specialties Group is placing this
- disk into the public domain for the benefit of all broadcast engineers.
- Each RF Specialties office stands ready to assist the broadcaster with his
- specific system design and equipment purchasing needs.
-
- Please feel free to copy this disk for your friends and associates. Or,
- any RF Specialties office will be glad to provide a copy for a nominal fee of
- $20. This charge covers the cost of copying and mailing the disk, and is not
- a charge for use of the software itself. The disk will then include a
- certificate good for $20 off any purchase of $150 or more from the RF
- Specialties office that supplied the disk. The names of people obtaining
- disks from RF Specialties will be kept on record and will be notified of
- future updates and enhancements that may be made available at a later date.
- If you have received this disk from a friend and wish to become a registered
- user, please send your name and address to:
-
- John Schneider
- RF Specialties of Washington, Inc.
- 11721 15th Avenue NE
- Seattle, WA 98125
-
- Your comments and suggestions, as well as information about any problems
- you observe, would be welcome. Please send them in writing to the
- above address.
-
- Minimum Requirements for this program: An IBM PC, XT or AT or compatible
- computer, with a minimum of 256 K of memory and one floppy disk drive, and
- MS-DOS 2.1 or a later version. No special graphics hardware is required,
- and all reports are designed to be printed on any standard parallel printer.
- While we have not tried other hardware and operating system configurations,
- the software should be directly executable on any 8086 or 8088 CPU
- machine running CP/M-86, MS-DOS, PC-DOS, TurboDos or Concurrent CP/M.
-
- There are two files on the disk. RFS.EXE is the RF Specialties program
- discussed above. WILLIAM.EXE is another public domain program that
- we hope you will enjoy. We acquired it from another source, and do not know
- who the author is.
-
- We hope you will enjoy the programs on this disk. And, the next time you
- are in the market for professional broadcast equipment or supplies, we
- hope you will remember the people that brought it to you: THE RF SPECIALTIES
- GROUP.
