the keyboard. It is very important that you include in your CQ the fact that you are asking for a G-
TOR contact. For instance, you might send:
CQ CQ CQ DE W0XI W0XI W0XI - GTOR
CQ CQ CQ DE W0XI W0XI W0XI - GTOR
CQ CQ CQ DE W0XI W0XI W0XI - GTOR
PSE ARQ IN GTOR MODE ONLY KKK
Be sure you include your callsign (as set by MYGTCALL) in the transmission. After you have typed
your entire CQ message, type [CtrI-C][E]. This will return your KAM Plus to G-TOR Standby mode
after all of the message has been transmitted. Your KAM Plus is then ready to respond if someone
calls you in G-TOR.
Tuning G-TOR
G-TOR signals are similar to AMTOR or PACTOR signals in that MARK and SPACE tones are used.
Hence the bargraph indicator will be lit at both ends when properly tuned. When you are linked to
another G-TOR station, the HF CON LED will be lit. The HF STA LED is used in G-TOR to indicate
the G-TOR speed. When the STA LED is off, the G-TOR rate is 100 baud, when FLASHING 200
baud, and when the STA light is lit constantly, 300 baud.
Monitoring G-TOR
In the G-TOR Standby mode, your KAM will monitor G-TOR CQ calls or other G-TOR FEC broad-
casts, which use the AMTOR FEC mode. In order to monitor two stations that are linked to each
other, you must use the GMON.EXE or GOFF.EXE program (for PC compatible computers) which we
have provided on the enclosed diskette. Real-time monitoring of linked G-TOR stations will require
a fairly fast computer (286/16 or better). This monitoring uses the GSCAN function of your KAM
firmware and processes the data in your computer. For slower computers, you may use the GSCAN
function and capture the raw data to a disk file. This allows you to use the GOFF program to view
the data, although it will not be real-time.
Entering G-TOR Standby mode
To enter G-TOR Standby mode simply type GTOR and press return from the command prompt
(cmd:). Your KAM Plus will then respond to any attempt from another station to link to you in G-
TOR. You must have ARQBBS OFF if you wish to talk to other stations from your keyboard. If
ARQBBS is ON, a station who links to you will be connected to your KAM Plus PBBS.
Calling another station on G-TOR
To call another station using G-TOR, at the command prompt (cmd:) enter the GTOR command
and the callsign of the station you wish to link to. For instance:
cmd:GTOR WK5M
Your KAM Plus will begin transmitting a link establishment frame and, if the other station is on the
air and in G-TOR Standby Mode, that station will respond to your link request and you will see the
message <LINKED to WK5M> on your screen. You can then start typing your message to the
other station. Since you started the link, your station will be the "Information Sending Station"
(ISS). After you have entered all that you want to say, use the [CtrI-C][E] directive to allow the
other station to send data to you. This causes the KAM Plus to send the G-TOR changeover se-
quence and you become the "Information Receiving Station" (IRS). While the other station is send-
ing data to you, you may force a changeover (seize the link) by typing the [
Ctrl-C][T] directive.
You then become the ISS again.
