Protect your radio tower and solar charged battery power supply by sending the correct Morse code transmissions.

Tap out alphanumeric characters in Morse code to prevent your radio station from being destroyed by the Morse code meteor attack!

Meteors may be destroyed in any order.

All levels start with a fully charged battery.
Each DIT uses 1% battery power. Each DAH uses 3% battery power.

Your battery charges at a nominal rate of 1% every 5 seconds, and total charge increases by 1% for every correct Morse code transmission.

In addition, you have two solar panels that each contribute 1% to the battery charge rate. If your solar panels are destroyed, there are no replacements for that game.

When your battery runs low, an SOS prosign bonus appears. Destroy this entity to recharge your battery.

Options include:

SOUND = ON/OFF toggles sound effects.
MUSIC = ON/OFF toggles background music.
TONE = 400Hz-800Hz sets CW sidetone.
NOVICE/GENERAL/EXTRA changes the speed of attack.
KOCH = OFF presents characters in random order.
KOCH = ON uses an order adopted by the Koch method:
K,M,R,S,U,A,P,T,L,O,W,I,.,N,J,E,F,0,Y,V,G,5,/,Q,9,Z,H,3,8,B,?,4,2,7,C,1,D,6,X
HINTS = ON/OFF decides whether to show Morse code representations.
MODE = LEARNING/GAME selects a slower, evenly paced learning mode or a more challenging game mode.
TX Adjust (hold) provides for some TX timing change.

Solar panels break when hit by a meteor and will no longer contribute any charging power.
If your radio tower is destroyed or if a meteor should hit a broken solar panel, the game is over and you are QRT.
Hold the Code Label (top center) to change the font size on some elements.
Hold the Home button to exit the game and return to the start screen.

You may use a straight key connected via an easily repurposed USB mouse and On-The-Go (OTG) cable for a more realistic tactile TX experience while defending your radio station:

Alternatively, you may use a 3rd-party device such as
My-Key-Mouse USB.

Certain settings on your Android device will curtail the sensitivity and performance of this app and should be turned OFF during its use. Default settings are recommended.

Two examples are Tap Duration and Ignore Repeated Touches (Settings > Accessibility > Interaction and Dexterity > Tap Duration/Ignore Repeated Touches).
