Receive Eight Circle Troubleshooting
There are several possible causes for a malfunction of a DX Engineering Receive Eight Circle
System. Testing the system is not difficult and can be completed in an hour or so. Separate circuits
for directional switching, Active Vertical Antenna power, and antenna phasing can each be affected
by a variety of cabling, connection and or component problems. If you are troubleshooting a new
system or using a replacement
DXE-RCA8B-1
Receive Eight Circle Array Controller unit, check
that the wiring from the Control Console to the Array Controller is correct and no damage has been
done to the lines.
Here are the most common causes of Receive Eight Circle malfunction, especially in a system that
was previously functioning properly:
START
80% of all Receive Eight Circle malfunctions are caused by
A, B
or
C
A
Broken/Shorted
Conductors
Animals, Chewed,
Punctured, Stretched,
or Broken
Green Connector may have
broken wire or is tightened
against insulation - not bare wire
B
Center Conductors
Slipped
Check all F connector
center conductor
wires. They may have
pulled inward.
C
Shorted/Open
conductors due to
water
Check feedlines and
control cable.
D
Zapped by lightning
pulse or RF overload
Make sure units are at least 1/2-
wavelength, on the lowest frequency,
away from any transmit antenna.
May want to use an optional
DXE-TVSU-1 Time Variable
Sequencer for AVA-2 units.
E
Damaged due to
lightning
Rare, but it can happen.
F
Damaged by animals
or insects
Animals have been known to relieve
themselves on the units and the urine
will corrode and damage electronics
Insects getting inside units and
shorting out electronics
