Note: The counter will not count below zero. The antenna will continual
moving but the counter will stay at zero if the antenna is not at it lowest
location.
Notice the direction of the antenna when pressing the UP button. If the antenna
is going the wrong way the polarity can be changed in the menu or the motor
wires can be swapped. See instructions under Polarity for details. Note: The
power supply wire for the controller can not be swap to change the polarity.
Only the motor control wires going to the antenna.
4. Place the Transceiver into a carrier mode. CW, RTTY, FM or FSK
5. Set Transceiver's power to 10 watts.
6. Set Transceiver to 10 meters.
7. Apply RF and release. The antenna controller should have displayed the
transceiver's frequency. The letter R will indicate RF is being detected. The
VSWR is indicated by the S. If the frequency is a little off it can be adjusted
under menu setting AJUST.
Programming:
The way the controller operates is it reads the frequency then moves the antenna
to the closest programmed setting that has been stored for that frequency. To
make the controller more accurate to move the antenna to the best resonate
location it may be necessary to program more than one setting within a band.
The controller will allow 8 different setting for each band.
Programming the Antenna.
1. Press the down Button to move the antenna all the way down. If the down
button moves the antenna the wrong way, the motor control wires can be
swapped or the polarity can be changed in the controller's menu POL. See
instruction under Polarity to change the polarity to the antenna's motor.
With the antenna all the way down the controller should be displaying 0 for
Pulse, 0 for Current and transceiver's frequency. If the counter is not at 0 refer
to CLRP to clear the counter. It is easier to tune the highest frequency first
since the antenna is already at its lowest setting. The transceiver will need to be
in FM, RTTY or FSK during this process. Power level about 10 watts of RF.
2. Set the transceiver to the desired frequency for the antenna to be tuned.
3. Move the antenna up to tuned (resonant) position. This should be where the
antenna is at its lowest VSWR. Normally this is done by pressing the MIC KEY
to create RF and move the antenna until you reach the lowest VSWR. Refer to
the Antenna's manual for question about tuning the antenna.
