4. After the antenna is tuned to the correct position. Verify the display is

showing the Transceiver's frequency and the P is showing the turns of the

antenna.

5. Press the SETUP button until the word STORE appears.

6. Momentary press the ENTER button. The display will read the Band and

memory location 1 in the bottom right of the display. Since this is the first stored

location for this band the location will be stored in memory 1.

7. Momentary press ENTER. The location of the antenna has been stored under

memory 1 for that band. The controller will store up to 8 positions for each

band. Normally 6, 10, 12, 15, 17 Meters will only need one setting for each

band to cover the whole band.

8. Repeat step 2 thru 7 to store a location for each band.

Some bands like 80 meters the antenna has to be moved to different spots to

keep the VSWR low within that Band. In this case it is best to program more

than one setting for 80 meters.

Example:

a. Set the transceivers Frequency close to the top of 80 meters. Move the

antenna to resonant (lowest VSWR).

b. Press the SETUP button until STORE appears.

c. Momentary press ENTER. 80 1 will appear.

d. Momentary press ENTER. This stored the position in memory 1 for 80

meters.

e. Watching the VSWR and applying RF. Start turning the transceiver's

Frequency down until the VSWR gets too high. (2.5).

f. While applying RF move the antenna UP until the VSWR drops below 1.5:1.

g. Press the SETUP button until STORE appears.

h. Momentary press the ENTER button. 80 1 will appear.

i. Momentary press the SKIP button 80 2 will appear.

j. Momentary press the ENTER button. This location is now stored under

memory 2 for the 80 meter band.

Repeat e thru f to store more locations under memory 3 thru 8 for the 80 meter

band if needed.

OPERATIONS:

Manual Mode:

Set the Transceiver to the desired Frequency.

Using CW, FM, RTTY, FSK or a steady tone thru the mic apply RF until the

display reads the transceiver's frequency.

If the antenna is not set for the correct band or the VSWR is too high momentary

press the TUNE button. With no RF applied the controller will move the antenna

to the programmed setting closest to the displayed frequency.

IF the VSWR is still too high press the TUNE button while applying RF. The

controller will adjust the antenna until the VSWR gets below 1.5:1. If the

VSWR does not get below 1.5:1 within a few seconds it will time out and stop.
