SKY CMD – 2
PREPARATION FLOW
The following steps should guide you to a good start of
Sky Command operation. First connect the Transporter to
the HF transceiver.
1
<On the Commander and Transporter> Select the
same VHF and UHF frequencies.
When using the TH-D72 to communicate with the
Commander and Transporter, set the TH-D72 as
described below.
<Commander>
Band A: VHF frequency
Band B: UHF frequency
Full Duplex: ON
Tone: ON (Band B)
<Transporter>
Band A: UHF frequency
Band B: VHF frequency
Full Duplex: ON
CTCSS: ON (Band A)
Note:
Configure the squelch to an appropriate level for both the VHF
and UHF band on the Commander and Transporter. If the squelch
is not set to an appropriate level, the transceivers may enter a BUSY
state due to noise signals and be unable to transmit.
2
<On the Commander> Access Menu 500 to program a
callsign (9 digits max.) for the Commander.
• You may enter your exact callsign; ex. W6DJY.
3
<On the Commander> Access Menu 501 to program a
callsign (9 digits max.) for the Transporter.
• This callsign must be different from the one for the
Commander. So you may add SSID characters; ex.
W6DJY-1.
4
<On the Transporter> Access Menu 500 to program
the same callsign as you entered in step 2.
5
<On the Transporter> Access Menu 501 to program
the same callsign as you entered in step 3. The same
callsign as you entered in step 2.
6
<On the Commander and Transporter> Access Menu
502 and select the tone frequency.
• Select the same tone frequency on both transceivers.
7
<On the Commander> Access Menu 503 and select
“Commander”.
• “Push [ 0 ] key to Start Commander!!” appears.
8
<On the Transporter> Access Menu 503 and select
“Transporter”.
Now the Commander and Transporter are in Sky Command
mode. For operations in this mode, see “CONTROL
OPERATION”. First switch ON the HF transceiver and press
[SYNC] on the Commander. To exit the Sky Command
mode, access Menu 503 and select “Off”.
Note:
◆
Unless you program callsigns, you cannot select “Commander” or
“Transporter” using Menu 503.
◆
On the HF transceiver, select 9600 bps and 1 stop bit (default)
using the Menu Set-up function.
◆
Adjust the audio level on both the Transporter and HF transceiver
while listening to audio output from the Commander. An
appropriate position of the AF control on the HF transceiver might
be in the range, 8:30 to 9:00.
◆
To distinguish your various stations or nodes, you can have up
to 15 Secondary Station IDentifiers (SSIDs); ex. W6DJY-1 to
W6DJY-15. You always have to put a dash between your callsign
and SSID number.
◆
Your station’s transmit signal can be received when the receive
frequency is 3 times the transmit frequency.
Example: Transmit frequency is 146.600 MHz and receive
frequency is 438.000 MHz.
ATTENTION:
Use only after verifying that there is no reception
disruption during communications.
