I - For best results, select a linear or switching power supply that is well regulated and
free of internally generated radio frequency
noise. “Birdies” generated by a poorly
filtered supply can often appear as signals in the SmartSDR Panadapter display.
The Anderson Powerp
ole™ connector
contains 45 Amp pins to minimize voltage drop
during transmit. The
RED
connection should be connected to the positive (+) lead of the
power source. The
BLACK
connection should be connected to the negative (-) lead of the
power source.
I - If you choose to use your own Powerpole cabling, be sure to properly size the wire
and the Powerpole connector to minimize voltage drop during transmit. Excessive
voltage drop can cause lower transmit power output levels.
7.1.1
Fused Internally at 30 Amps
The power input has a protective 30 Amp a
utomotive “blade type”
fuse inside the radio
case. In the event you ever need to replace the internal fuse, remove the top cover and
locate the fuse in the rear corner of the PA board just inside the case adjacent to the
Anderson Powerpole connector.
!
–
NEVER USE A FUSE WITH A CURRENT RATING HIGHER THAN 30 AMPS! FAILURE TO
PROPERLY USE THIS SAFETY DEVICE COULD RESULT IN DAMAGE TO YOUR RADIO,
POWER SUPPLY, OR CREATE A FIRE RISK.
7.2
TRANSCEIVER ANTENNA PORTS [1,2]
Transceiver antenna ports are SO-239 50 ohm connectors. Refer to SmartSDR
documentation for explanation on how to select which port is active.
! - WARNING: THE FLEX-6400/FLEX-6600 ARE CAPABLE OF GENERATING RF POWER
LEVELS OF 100 WATTS. HIGH RF LEVELS WILL CAUSE SEVERE RF BURNS. NEVER TOUCH
THE TRANSCEIVER ANTENNA PORT, AN EXPOSED COAXIAL CABLE END, OR A
CONNECTED ANTENNA WHILE THE RADIO IS IN THE TRANSMIT MODE.
!
–
NEVER CONNECT OR DISCONNECT ANTENNAS WHILE IN TRANSMIT MODE. THIS
MAY CAUSE ELECTRICAL SHOCK OR RF BURNS TO YOUR SKIN AND DAMAGE TO THE
UNIT.
!
–
THIS UNIT GENERATES RADIO FREQUENCY (RF) ENERGY. USE CAUTION AND
OBSERVE PROPER SAFETY PRACTICES REGARDING YOUR SYSTEM CONFIGURATION.
WHEN ATTACHED TO AN ANTENNA, THIS RADIO IS CAPABLE OF GENERATING RF
ELECTROMAGNETIC FIELDS WHICH REQUIRE EVALUATION ACCORDING TO YOUR
NATIONAL LAW TO PROVIDE ANY NECESSARY ISOLATION OR PROTECTION REQUIRED,
WITH RESPECT TO HUMAN EXPOSURE!
