4 Following the instructions provided with your MCP or
RTTY equipment, enter the key sequence at your
RTTY keyboard to select the transmit mode.
The “ON AIR” indicator lights.
•You may instead press [SEND] to manually
select transmit.
5 Adjust the CAR control so that the meter reads in the
ALC zone but doesn’t exceed the upper ALC zone
limit.
6 Begin sending data from the keyboard.
7 When finished transmitting, enter the key sequence
from the RTTY keyboard to return to receive mode.
The “ON AIR” indicator goes out.
If you are manually switching between transmit
and receive, press [SEND] to return to receive.
Use Menu No. 21 (PKT.OUT) to select the
appropriate AF output level. The AF gain control
cannot be used for this adjustment.
Traditionally, the lower sideband is used for FSK
operation. Pressing [FSK/R] reverses the transceiver
to the upper sideband.
RTTY FREQUENCIES
ERROR-CHECKING MODES (AMTOR/ PACKET/
PACTOR/ G-TOR/ CLOVER
Due to their error-handling capability and speed of
transmission, these modes are more efficient than
earlier forms of digital communication by machine. In
the case of G-TOR
TM
, it was developed specifically to
handle the adverse conditions of communicating across
the solar system with spacecraft during their missions.
6 COMMUNICATING
On most HF bands, audio frequency shift keying
(AFSK) is used. This method of modulation uses audio
tones therefore either the LSB or USB mode should be
selected. Traditionally, LSB is used similar to RTTY with
the exception of AMTOR which is normally operated
using USB.
In some countries, the licensing authorities permit F2
operation on some frequencies in the 10 meter band.
For this type of operation, select the FM mode.
Note:
When using the SSB mode for digital operation, use a fast
AGC setting and switch OFF your Speech Processor. Also, take
advantage of the different filter bandwidths available via Menu No. 19
(PKT.FIL). Remember to set Menu No. 19 to OFF for voice operation
since the filters available are too narrow for voice.
1 Select the operating frequency.
2 Press [LSB/USB] to select upper or lower sideband
mode.
For F2 operation, select the FM mode by
pressing [FM/AM]. Switching Menu No. 59
(FM.BOOST) to ON may lower error rates for FM
operation. The Menu No. 19 (PKT.FIL) filters for
digital operation cannot be used when the FM
mode is selected.
3 Select the ALC meter function by pressing [METER].
4 Following the instructions provided with your TNC or
MCP, enter the calibrate mode so you can generate
a mark condition.
The “ON AIR” indicator lights.
5 Select the correct setting for Menu No. 20 (PKT.IN)
so that the meter reads in the ALC zone but doesn’t
exceed the upper ALC zone limit.
6 Exit the calibrate mode.
The “ON AIR” indicator goes out.
7 Send commands and data.
The transceiver will briefly transmit each time it
sends your commands and data, or when it
acknowledges transmissions from other stations.
Use Menu No. 21 (PKT.OUT) to select the
appropriate AF output level. The AF gain control
cannot be used for this adjustment.
