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.
We hope you will enjoy the program 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.
