Quick Start Guide for the NCC-2
Receive Antenna Phasing Controller

DXE-NCC-2-Quick Start -INS Rev 0b
PLEASE
- Read this guide completely before applying power or transmitting RF.
You can cause serious damage to the NCC-2 and your receive antenna system by making incorrect
connections to this unit. This type of damage is NOT covered by warranty.
If after reading this guide and the complete NCC-2 manual you still have any questions about the
hook up of the NCC-2 for your system, please call DX Engineering for technical assistance.
Make these connections first then perform the Transmit Safety Test
described on page 2 of this guide.
Make connections to the
NCC-2
as follows:
Connect a standard shielded audio style cable between the
RADIO PTT
Phono
connector and a transceiver keying output that provides a ‘ground on transmit’
connection. Some modern transceivers have a rear panel amplifier control jack typically
labeled as "TX", "AMP", "Send” or "TX GND" that pulls low when the transceiver is
keyed. (Check the user manual for your radio).
Note:
Kenwood transceivers have a 7-pin
DIN labeled “REMOTE”. Use the
DXE-KWD-RTR
cable.
ACC PTT
connector on the
NCC-2
is a keying pass-through used for keying another
accessory such as an amplifier or sequencer.
Do not
use this connector for a transceiver keying
line. See warning on second page of this guide.
Connect the NCC-2
RADIO
jack to a transceiver antenna jack with a standard coaxial cable.
When using two receiving antennas, connect the first one to the
CH A RX ANT IN
BNC or F
Connector.
When phasing a receive only antenna with a transmit antenna, connect the included BNC patch
cable between
MAIN ANT OUT
and
CH A RX ANT IN
.
Connect the second receiving antenna (or local noise source antenna) to the
CH RX B ANT IN
BNC or F Connector.
Connect a well filtered, fused power source of +13.8 to +21 Vdc 2A minimum
to the
MAIN PWR
jack
to the NCC-2 using the supplied 2.1 mm plug. Input DC
line should be fused at 3 amps to protect circuitry. Power will be fed through the
bias tee circuitry to A and B Ports if individually enabled.
See the manual for jumper settings
.
Proceed to the
Transmit Safety Test
on page 2.
--------------------------------
NEVER
connect the
MAIN ANT OUT
connector of the NCC-2 to a transceiver RF output!
