Mode: Morse, Baudot and ASCII Host: At
“n”
0 to 250, signifying the length of time (in units of 100 mS) to delay before sending text.
ATXRTTY allows Morse, Baudot or ASCII characters to be transmitted automatically whenever they’re typed and
the TNC is in the Converse mode. When all the characters in the buffer have been sent, the DSP reverts to receive.
The number
n represents the length of time from the last character typed to the dropping of PTT. This feature makes
the repeated use of the commands
RCVE
and
XMIT
unnecessary.

“
n ” 0 to 6 specifies a code from the list below. (RX = Receive; TX = Transmit)
CODE
Meaning Morse Baudot AMTOR PACKET
0 International RX/TX RX/TX RX/TX
1 US teleprinter RX/TX RX/TX
2 Cyrillic RX RX/TX RX/TX
3 Transliterated Cyrillic RX RX RX
4 Katakana RX/TX
5 Transliterated Katakana RX
6 European RX RX
Not all the codes in the list above can be transmitted.
Note: FCC Part 97.69 and 97.131 calls for the use of ( CODE 0 ) “International Telegraph Alphabet
Number 2” five unit teleprinter code. The Baudot characters “$”, “#” and “&” are not permitted for use by US Amateurs.
CODE 0 : International
In Morse, this means the International Morse Code. For Baudot and AMTOR, this means the ITA #2 teleprinter
code, which is internationally recommended for Baudot and ’TOR communications and shown below:
lowercase set UPPERCASE SET
1 2 3 4 5 6 7 8 9 0 - = ? ? ? ? ? ? ? ? ( ) ? +

The following special Morse characters are available as receive only and are used in non-English Morse alphabets.

In response to requests from European customers, the “national” ITA#2 characters unassigned in the US have been
made available for both transmission and reception. FIGS-F, FIGS-G and FIGS-H have been assigned characters
according to standard use and are shown below. Note that some national alphabets use these characters for accented
letters not appearing in English.
