MARK and SPACE commands in the KAM’98 to match those tones. For in-
stance, the default MARK and SPACE in theYaesu FT-1000 are 2110 Hz for
MARK and 2310 Hz for SPACE.
Caution:
When you are linked to another station and you want to break the link,
you should use the <Ctrl+C> A directive. This directive will attempt to send the
proper QRT sequence to the other station, but if the KAM’98 receives an invalid
response sequence (unrecognized CS code), it will immediately return to GTOR
Standby and discard any pending data. If you attempt to break the link with the
<Ctrl+C> X directive, the KAM’98 will attempt the QRT sequence, but will only
return to packet mode after receiving the proper acknowledgement (CS code) or
after GTERRS attempts to break the link.
This could take a long time.
When you attempt to link to a nearby station, it is possible that the transceivers
(yours and the other station’s) may not switch fast enough to permit a link to oc-
cur. In this case, we suggest that both stations set the TXDTOR command to a
higher value (try 7, 8, or 9). This has been proven to allow links on very short
paths with very slow radios.
If you use an external power amplifier with your HF transceiver, you may set a
time delay to key your transmitter before the audio is sent to your radio by using
the PREKEY command. This command will allow your amplifier to turn on be-
fore full transmitter power is applied. You may also set the POSTKEY command
to stop the transmit audio before releasing the PTT line to your transceiver. (note
that PREKEY adds delay time before data begins.)
+ NOTE: Do not change TXDTOR, PREKEY, or POSTKEY values while you are
linked. This is only possible with Host mode programs, but changing these values
while linked will cause the link to fail.
Binary Files and G-TOR
The G-TOR mode provides complete data transparency, allowing binary file
transfers between G-TOR stations. The ability to send and receive binary files in
this mode will depend on the termal program you are using. Since G-TOR pro-
vides complete error detection and correction, binary files should sent in a raw
data mode—that is, no error correction protocol (such as X-modem) needs to be
used from your terminal program.
