After typing FEC, your PK-900 displays the system status:
MODE: AMTOR FEC IDLE
RADIO 1: TX on
As you send your traffic the Status will change back and forth from
IDLE to TFC. Whenever you stop typing, the IDLE status is displayed.
7.4 AMTOR Operating Tips
The following "Special Function Characters" and immediate commands are
included for AMTOR operating convenience.
Immediate Commands from the Command Mode:
"ARQ <SELCALL>" Starts Mode A selective call and forces Converse
"FEC" Starts Mode B transmission and forces Converse
"SELFEC <SELCALL>" Starts Selective Mode B transmission
"R" Stops sending immediately, forces AMTOR Standby
"AM" Stops transmission, forces AMTOR Standby
"AL" Forces re-synchronization in ALIST (AMTOR Mode A
Listen)
"L" Forces LETTERS case in receive
"N" Forces FIGURES case in receive
Special Function Characters embedded in transmitted text:
<CTRL-B> Sends your AAB string as a HERE-IS message
<CTRL-D> Stops sending when the transmit buffer is empty
<CTRL-E> Sends a "Who Are You" request to the other station
<CTRL-F> Sends call sign in Morse and shuts off transmitter
<CTRL-N> Sends FIGURES character
<CTRL-O> Sends LETTERS character
<CTRL-T> Sends the TIME if the DAYTIME clock has been set
7.4.1 ARQ Break-In (ACHG Command)
In Mode A (ARQ), when you're the "Information Receiving Station," you
can use the "ACHG" command to interrupt the distant station's comments.
As the "Information Receiving Station," you normally rely on the
distant station to send the "+?" to "change-over" at the end of his
comments. ACHG is a command that forces both systems to reverse the
"Information Receiving" and "Information Sending" status of the link.
o Use the ACHG command only when really needed to interrupt the
distant station.
7.4.2 Entering Your Auto-AnswerBack (AAB)
AMTOR allows you to request the identity of the station you are
conversing with by sending your PK-900 a <CTRL-E>. This causes the
PK-900 to send a FIGS-D (WRU) request to the other station. Many
remote Bulletin Board Stations rely on the WRU for identification.
For this reason, you should set your own Auto-AnswerBack (AAB) message
to "DE YOUR-CALL, MYSELCAL, MYIDENT". Your PK-900 will automatically
