PK-232 MBX Operating Manual - N3UJJ

PK-232 OPERATING MANUAL COMMAND SUMMARY
CODE 1:
US Teleprinter
In Morse, this has no effect; the unit will use the International Morse Code and
NOT the American Morse code. In Baudot and AMTOR, the US teleprinter character
set shown below is used. Users of CODE I should be aware of the following:
The US teleprinter code (CODE 1) makes the “1”, “$”, “,” and “#” characters
available in Baudot and AMTOR. The WRU character, “=” and the "+" characters are
lost when CODE is set to 1. Since there is no “+” character in the CODE I
character set there should be no way to turn over the AMTOR link and change from
ISS to the IRS. To avoid this problem, the PK-232 sends a FIGS-Z when the "+"
key is pressed in AMTOR and responds to the reception of the "FIGS-Z" '?"
sequence so the direction of traffic can be reversed.

Please Note that for U.S. Amateurs, the F.C.C. regulations require Baudot and
AMTOR transmissions follow CCIR Recommendations which require the ITA#2 (CODE 0)
be used. Technically, it is illegal to use CODE 1 on the U.S. Amateur bands.
MARS operators and Amateurs outside the U.S. may find CODE 1 useful.
CODE 2:
Cyrillic
This code causes a translation to an artificially extended ASCII, so that all
received characters are converted to single ASCII characters. The character set
used prior to July 1991 was arbitrary, but we have now changed the character set
to one which we believe to be used presently in the USSR.
The extensions used in Morse reception are shown below:
