installed F connector should have the center conductor protruding 1/4 inch beyond the shell when
viewed from the side. Check all F connectors!
C) Shorted or opened conductors caused by water migration into a control line or a feedline.
Over 80% of all Receive Eight Circle malfunctions have been caused by the above system problems. A
thorough inspection and subsequent testing of each control cable, RF cable, and their respective
connections, will uncover the cause of most Receive Eight Circle troubles. Here are a few other causes
for Receive Eight Circle malfunction:
1) One or more burned out Active Vertical Antenna units model AVA2 or AVA1, due to
lightning pulse or high power RF overload. One-half wavelength on the lowest frequency is
the minimum distance between the Active antennas and any transmit antennas. If that
distance is less and high power is used, then the Time Variable Sequence Unit, (TVSU) must
be used to interrupt power to the AVA2 units.
2) Damaged Receive Eight Circle unit due to lightning. This has been reported only a couple of
times and is not very likely.
3) Active units that were damaged by animals. Once we received actives damaged by an animal
that relieved themselves on the antennas and AVA units, as if they were “trees”.
The above items are the most common failure points in the system needed to be checked.
If necessary, the following further troubleshooting procedure may assist in finding the malfunction.
Receive Eight Circle Control Troubleshooting Procedure
1) Test the modified
DXE-CC-8A
Control Console unit, which should be connected only to the control
lines of the Receive Eight Circle System. When the modified DXE-
CC-8A
is connected to the control
cable, do all of the selected switch position LEDs light normally?
