The green RX LED is lit
JUPITER's receiver is operational.
1.4.5. TX LED
The red TX LED is lit when JUPITER is
transmitting.
1.4.6. AUTOMATIC LEVEL CONTROL
LED
The red ALC LED lights when transmit
power peaks reach the proper level. Use
it for adjustment of MIC gain. The LED
will flash when JUPITER is transmitting
at proper ALC level for CW or SSB.

1.5. REAR PANEL
CONNECTIONS
There are several rear panel connections
on JUPITER, to interface other station
equipment with the transceiver.
15,1. 50-ОНМ АМТЕММА
This 50-239 jack connects to a suitable
(SWR < 2:1) 50-ohm coax-fed antenna.
1.5.2. GROUND
А wing nut connector provides Ше
means to connect JUPITER to your
station ground. A good ground system is
essential for optimum operation of any
transmitter. The best solution is to
connect all the station equipment chassis
together using a heavy flat ground braid.
Use another length of braid to connect to
a ground rod. Keep all connections as
short as possible. If you are not using a
linear amplifier a less ideal ground will
suffice. A short ground connection to
the copper cold water plumbing pipe is
usually acceptable.
Antenna type and proximity to the
station are also factors іп choosing
ground methods. With good resonant
antennas located away from the station,
the AC ground in your house wiring may
be adequate.

1.5.3. DC POWER
This is a 2-pin MOLEX™ connector for
connection of a suitable 13.8 VDC power
supply with 20-ampere capacity. See
paragraph 1.1 for details.
Please observe correct polarity when
using this jack or damage will result.
1.5.4, FUSE
A 25-ampere blade fuse protects JUPITER’s
transceiver wiring if an internal fault should
occur. JUPITER’s packing kit includes a
spare fuse (#27074). These fuses are
commonly available at automotive supply
stores.
1.5.5. ACCESSORY JACK
The ACCi jack is for interfacing equipment
requiring audio in/out connections, like a
TNC or phone patch. These connections
also provide for digital mode operation. For
information on using JUPITER in digital
modes, see section 2.6.4. Figure 1-4 shows
wiring information. Use the supplied cable
(#46176) or an equivalent to connect
accessories.
