FUN AND GAMES WITH KENWOODS LATEST DUAL BANDERS

UNDOCUMENTED FEATURES ON THE TM-741A and TM-732A

by Fred Lloyd, AA7BQ

Over the weekend, I took some time to experiment with my Kenwood mobile
rigs and was quite surprised at what I found.

TM-741A

The 741 has three undocumented games built into it which are somewhat
amusing.  There is a "slot machine", a "space invaders" and a "musical
keyboard".

To activate, press and hold the F and MUTE keys while turning on the
power.  The display will come up showing  -1-   -2-   -3-
To activate game 1, press the Band 1 (leftmost) control,  for game 2,
press the Band 2 (middle) control, and for game 3, the Band 3 (rightmost)
control.

Game 1 - "Slot Machine"

To start the wheels rolling, hit the MUTE key.  The display shows
"0   0   0"    Then, press the Band 1, Band 2, and Band 3 keys in
order to stop each of the wheels in turn.  The radio emits a "phaser"
sound when the wheels stop.  I haven't hit the jackpot yet, so I don't
know how it acts when the three numbers match...  Use the VFO key to
cancel the game and return the radio to normal operaton.


Game 2 - "Space Invaders"

Activate game 2 as shown above.  The leftmost display will clear to
all zeros.  The center display is the "target".  The rightmost display
is some sort of shot counter.  Manipulate the lower button row to
play the game.  The rig plays a tune when the game is over.  Scores
advance (with the phaser sound) as the game progresses.  I don't know
much more about it and don't exactly know the object of the game but
I'm sure that someone will figure it out.  Again, the VFO key cancels
the game mode.

Game 3 - "Musical Keyboard"

Activate game 3 as shown above.  The display says "Enjoy Sound Play".
Each of the keyboard controls now plays a distinct tone.  The VFO key
cancels the mode.  There are apparently 15 different tones available.

-------
It's also worth mentioning that the radio receivers continue to operate
while game playing takes place.  Presumably, one could idle away the 
time playing games while sitting by the radio and listening for 
important calls...
