PK-232 MBX Operating Manual - N3UJJ

PK-232 OPERATING MANUAL COMMAND SUMMARY
In Baudot and AMTOR, Russian transmitters use a third register to transmit
Cyrillic characters in addition to the LTRS and FIGS. They use LTRS to transmit
the Roman alphabet. As LTRS and FIGS characters are used to access the first and
second registers, they use the BLK or NUL character '00, to access the third
register. The PK-232 displays third-register characters as lower-case alphabetic
characters, and all FIGS characters in CODE 0 with the following exceptions:
Character Code 2 English Pronunciation
FIGS-F $7C | E
FIGS-G $7B { SH
FIGS-H $7D { SHCH
FIGS-I $60 ‘ YU
3rd-Q $71 q YA
If several words end in "DJ", "OW" or "OGO" the transmission is probably Russian.
There is no separate Baudot combination for the CH character. The Russians use a
"4" because the Cyrillic character for CH resembles a "4".
It is safe to leave CODE set to 2 if you are not sure which alphabet the
transmitting station is using. You will be able to see the message in either
alphabet with minimal garbling, and you can then set CODE to either 0 or 3.
Another interesting side effect of being able to send and receive in CODE 2 is
that it is now possible to send and receive both upper and lower case text in
Baudot and AMTOR modes. To do this, both station must have CODE 2 enabled and of
course both must be running 1991 or later firmware in their PK-232's. Other
users will see only upper case characters and not be aware that anything unusual
is happening, as the feature merely inserts NULL characters at strategic times.
An Timewave PK-232 using CODE 2 in QSO with a unit in CODE 0 (or any other
equipment) will exchange data in upper case only, with no adverse effects.
This feature may be advantageous to users of the AMTOR MailDrop who want their
messages to be forwarded to the packet network. The ability to send and receive
upper and lower case characters in AMTOR should improve message readability when
it is translated to Packet and vice versa.
CODE 3: Transliterated Cyrillic
This code is similar to CODE 2, except that some characters are transliterated
into English phonetic equivalents for easier reading.
