SWBC INTERVAL SIGNALS version 1.0
PUBLIC DOMAIN SOFTWARE - Copyright (c) 23 Jul 91, FineWare, Inc.

Welcome to SWBC Interval Signals v1.0. The system requirements
for operation of this program are an MS-DOS Computer with at least
256k of memory and a Color Graphics Adapter (CGA). The distribution
file INTSIG10.ZIP should contain the following:

IS.EXE - The SWBC Interval Signal v1.0 program
SIGxxx.SI1 - Interim interval signal data files (79).
SIGFIX.EXE - interval signal data file converter.
INTSIG.DOC - This Text

PURPOSE. There has been a minor uproar to the fact that the
World Radio TV Handbook (WRTH) has omitted the interval signal music
in its 1991 Edition. The data files in this package contain 79 inter-
val signals compiled from past editions of the WRTH as far back as
1979. Instead of providing raw printed music, however, the data files
are constructed such that they may be played through your PC's
speaker.

SETUP. First, it is suggested that the following commands are
included in the user's CONFIG.SYS file:

DEVICE=ANSI.SYS
FILES=20
BUFFERS=15

Second, if a hard disk is being used to run SWBC Interval Sig-
nals, make a subdirectory for the program to reside, and un-ZIP all of
the files contained within INTSIG10.ZIP there. Since there are a
lot of small data files, it is recommended that this program be setup
and run on a floppy disk. The small files, only totalling around
35.5k will only eat up nearly 85k of floppy disk space, whereas four
times this amount (323k) would be required on a standard hard disk.

Lastly, in order to run SWBC Interval Signals for the first time,
it is essential that the user convert the interim data files based
upon the PC's clock rate, using the SIGFIX utility. This is required
because the software provided uses a special algorythm previously de-
veloped in the Polyphonic Music Player v1.2 (written by Mike Talvola,
Agora Hills, CA) to send three-tone polyphonic music to the PC's
speaker. The SIGFIX utility adjusts the data files in pitch and tempo
to accomodate the differing speeds of the PC, XT, and AT-2/3/486 class
machines. SIGFIX is run as follows:

SIGFIX clock(MHZ)

i.e. for the standard 8MHZ PC/AT:

SIGFIX 8

SIGFIX will then read all of the *.SI1 data files, one by one, conver-
ting each while displaying the stations represented. To avoid confu-
sion, the new files are given the extension *.SIG. The allowable
range of clock speeds to use are between 4.77 (standard PC, PC/XT) and
35.8 (better than a 33MHz '386).

RUNNING. All that is required to run SWBC Interval Signals is to
type 'IS' at the DOS prompt. The program will read the titles of all
of the converted data files, and display them in a menu-like fashion.
Simply use the cursor keys to move the selection bar to the desired
interval signal to play, and hit ENTER to play it.

Do not be surprised if at first the pitch and tempo do not appear
to be correct. This is to be expected if using higher class 386 and
486 machines. If desired, the SIGFIX utility may be run again to fine
tune the sound, since PCs never run exactly at their specified clock
rates. If the selections sound too high and too fast, add one or two
MHz to the value used the first time SIGFIX was run, and run it again.
As well, if the the selections sound too low and too slow, subtract
one or two MHZ.

Once the proper pitch and tone is created, the *.SI1 files (not
the newly created *.SIG files), may be deleted. It is recommended,
however, that the *.SI1 files be kept somewhere for safe keeping, in
case you wish to install the program on another machine.
