System unit. Use a steady, non-fading ground wave signal from a low or medium power daytime AM
Broadcast station that is over 10 miles away, on a frequency high in the band, or another constant signal
source near 160 or 80 meters, well away from the array, to test that each Active Vertical receives the
same signal level. Do not use sky wave or night signals for these signal level tests.
9) Test reception of each Active Vertical Antenna by connecting each antenna feedline, one at a time, to an
activated port on the Receive Eight Circle System. This assumes that a good port has been identified
and is functioning properly. Normal reception must be confirmed from each antenna. If any antenna is
not providing the proper RF signal level, move the AVA unit to a known good feedline position to rule
out the possibility that a bad feedline is attenuating the RF. If one or more Active Receive Verticals
produce a low or no signal, then the AVA unit at the base of that antenna may not be receiving power.
Retest for DC power at the antenna end of that feedline. If + 10 to 18 Vdc is found, then the Active unit
may need to be serviced or replaced. New
AVA2 units are available separately by calling DX
Engineering.
10) If all Active Verticals tested provide the same signal level, then change switching voltages to activate
the other ports, one at a time, and test each Receive Eight Circle System unit port, using one of the good
antennas, testing for the same level of reception. If one or more ports is dead or has diminished
reception, there may be a problem in a delay line or in the Receive Eight Circle System unit.
11) Using tested or replaced delay lines and connectors, if one or more ports is dead or has diminished
reception, the Receive Eight Circle System unit may require service or replacement.
At this point, the problem in your system should have been identified. If you need additional assistance from
DX Engineering, feel free to call or write. Detailed discussions of system function, connections, and
troubleshooting is best handled by telephone, Monday through Friday, 8:30 am to 4:30 pm Eastern Time, at
