Options Menu
In the Options menu all supported functions for a particular mode or functionality are collected - the
menu is adapted to each individual mode. The Options menu will therefore appear with different contents
depending on the mode or functionality selected.
Alphabet...
The Alphabet menu has options for transparent and normal output. The normal output includes fonts for
e.g. Latin, Greek, Cyrillic, Hebrew, Arabic alphabets.
The ASCII character sets for output in German, Bulgarian, US, Swedish, Danish-Norwegian, Chinese
or other alphabets may also be selected.
Skyper, an alphabet which is used in POCSAG mode in Germany, is also available.
The transparent alphabet includes output of non-printable characters of a data transmission, e.g. ITA-2
control characters like Letter Shift and Figure Shift, or undefined upper case characters. In normal alpha-
bets these characters are not output.
Bit Inversion Mask
One or several data bits may be inverted by using the Bit Inversion Mask item in the Options menu.
The Bit Inversion Mask can be entered in three different ways:
 In the top input box a decimal number between 0 and 31 may be entered
 In the center input box the same number may be entered in binary format with the least signifi-
cant bit to the right
 In the bottom check boxes a logical "1" is entered with the mouse by clicking in the check box
Bit Inversion is only implemented for ITA-2 (Baudot) based bit streams.
CRC Recognition
An automatic detection of the CRC can be switched on/off with Options | CRC Recognition. The detect-
ed CRC is displayed in the decoder status bar.
