HOW TO PLAY CALLGAME (CALLGAME.EXE)

   CALLGAME is played by two persons, both of whom must be 
capable of copying code at the speed selected. The player 
designated as "the Op" is on a DXpedition. The Op will use a 
key and some sort of tone-producing device to respond to the 
callers trying to work the DXpedition. If nothing else is 
available, a vocal imitation of Morse can be used. The 
second player, "the Controller", monitors the Op's keying 
and controls the action.
   Play starts when the Controller enters the command line 
that initiates the execution of CALLGAME. (See Section II of 
README.TXT for details.) CALLGAME first asks the Controller 
for audio frequency and code speed preferences, then spends 
about 10 seconds synchronizing itself with the computer's 
processor chip. At the end of this period, the computer 
sounds the first call and displays it on the monitor for the 
benefit of the Controller. The Op will be given ample time 
to copy the call and acknowledge it with the report 5NN. In 
other words, the call VP2E/KC7IG must receive the 
acknowledgment VP2E/KC7IG 5NN. If the Controller considers 
the exchange correct, depressing the space bar will trigger 
a return exchange from the computer of 5NN TU. The Op will 
have time to respond TU before the next call arrives.
   If the Op didn't copy the call, there are two choices. 
The first, and by far the better, is to confess the fact by 
sending VP2E/? or something of that kind. The Controller 
will immediately press one of the keys directly above the 
space bar to trigger a repeat of the missed call. If the Op 
chooses to do nothing, the computer sends the call a second 
time if the Controller does not respond within the time 
frame allowed; this slows things down and deprives the 
players of some of the excitement of the game.
   The Op is not given a third chance by the disgusted 
caller who promptly leaves the pileup for greener pastures 
elsewhere. Then, a new call will be heard, not necessarily 
at the same speed or frequency! To make things a little more 
interesting, the frequencies and speeds heard are selected 
by the computer in ranges that center on the preferences 
selected by the Controller.
   When the last call in the input file has been answered 
(or blown!), the computer congratulates the Op and reports 
the number of QSOs "in the log". The game will be terminated 
before the end of the input file has been reached if the 
Controller responds to a call by depressing the ESC key.
   When you are ready for a greater challenge than CALLGAME 
offers, let me recommend PED.EXE by Mas Kozu, JE3MAS. It 
goes far beyond CALLGAME and is so realistic that I find 
myself pleading with slow callers to hurry before my QSOs-
per-hour rate drops into the single digits! In the mean 
time, I hope you'll enjoy CALLGAME and the other XTRAPLUS 
programs. GL ES DX DE KC7IG.
