each position of the highlight you may
rotate the MULTI control to step the
stored setting through its range of
choices. You will find the MULTI
control less sensitive in this mode than
with other uses, so tum it until you have
seen its range of choices.
3.4. TRANSMITTER SETTINGS
3.4.1. Transmitter On/Off
А responsible amateur radio operator
takes steps, per FCC regulations, to
prevent accidental ог unauthorized
transmission when he is not in the shack.
To disable or enable JUPITER's
transmitter, push MNU and select the
TRANSMITTER item by turning the
main tuning knob to highlight it. Rotate
the MULTI control to select ON or OFF
as required. Push MNU again to return to
the previous screen.
3.4.2, Transmitter Meter
JUPITER's meter display always
indicates signal strength in the receive
state, but you may choose to display
either output power or standing wave
ratio while transmitting. Tum on the
MNU screen and set the highlight on TX
METER. Turning the MULTI control
will select either PWR or SWR.
3.4.3. Output Power
This controls JUPITER's transmitter
output power. Push the PWR button and
use the MULTI control to adjust forward
output power from approximately 5 to
100 watts. The control is nearly linear in
indicated percentage versus actual RF
power.
3.5. CW SETTINGS
3.5.1. Tx Enable Keying Loop
The TX EN and TX OUT connectors оп
JUPITER's rear panel will form a keying
loop to operate a QSK (full break-in
3-2
CW) linear amplifier with proper T/R
sequencing. See 3.15 below for
information on connecting an amplifier.
3.5.2. CW QSK Delay
Теп-Тес transceivers have always
offered the full break-in operation that
many (but not all) CW operators prefer.
For reasons of particular preferences and
possible limitations of external
equipment, JUPITER's transmit-to-
receive switching time is another СУМ
set-and-forget item on the Menu screen.
Select CW QSK DELAY from the Menu
and adjust the timing with the MULTI
control The range of adjustment is
from nearly instantaneous to 2.6
seconds.
3.5.3. CW Keyer
This function сап accept direct
connection of keyer paddles to
JUPITER'S built-in keyer via the front
panel KEY jack. JUPITER’s default
setting is to accept a 1/4" mono key plug
from a straight key, bug, or external
keyer. To enable the internal keyer, for
use with your paddle, select CW KEYER
on the MNU and use the MULTI knob to
turn on the keyer.
The keyer will default to OFF when
power is removed. This prevents
inadvertent transmission if a 2-circuit
plug is in the KEY jack as power is
applied to the transceiver. Figure 3 in
chapter 1 shows proper wiring of keyer
paddles and a 1/4-inch stereo plug for
use with the internal keyer.
3.5.4. Keyer Speed
The KEYER SPD button enables control
of JUPITER's internal keyer speed.
Activate the button by pressing ALT +
RF, and set the speed with the MULTI
control. The range is from 1 to 63 WPM.
3.5.5. CW Weighting
This control adjusts the ratio of dit-to-
space timing to suit operator preference
