During the tuning procedure, apply only enough RF power from the exciter to get a meaningful reading on REF meter Ml in its most sensitive position.
The number following the “S” tells how many wires are at the connection. Try not to disturb this nut when you perform the following steps. Tighten the setscrew onto the inductor shaft. It is impor- tant that you tune up an exciter on a “dummy load” before you use it with your Antenna Tuner. Meter Ranges Forward 2 ranges Low — watts.
Also indicates standing wave ratio. Start the free end of the tension rod into hole BL in the rear inductor end plate. Check the capacitors on the back of SW3 to make sure that none of the capacitor leads touch one another, and that none of them are shorted to other switch lugs. The coaxial switch will select any of four outputs to antenna feedlines or dummy loads.
Mark each capacitor rear plate assembly for identification in one of the next two steps. The illustrations in the Manual are called Picto- rials and Details. If the SWR is greater than 3. Place a shaft coupler onto the flatted end of the detent shaft. Do not include any wooden cabinets or color televi- sion picture tubes, as these are easily damaged in shipment.
Turn these nuts onto the rods until they are snug against the ceramic insulators and flat fiber washers.

Occasionally, a “precision” or “power” resis- tor may have the value stamped on it. Then push the folded end through the center of the dual core assembly and wind one turn onto the cores. If you are not using an amplifier, connect the coaxial cable from the exciter’s RF output con- nector directly to input connector ]6 on the rear panel of the Antenna Tuner. SWR indications on the reflected meter provide direct readings from 1: Do not overtighten the nuts and break the insulator.

On each of the four. F ceramic capacitor to SW3 lug 4 S-l. Place a flat washer, the male ceramic element, and a fiber washer on the stud. Tighten these nuts until they are snug, Refer to Pictorial Illustration Booklet, Page 9 for the following steps. Secure the strap at AN with a nut. Set one of these springs aside until it is called for during the assembly of the transmitter matching capacitor. Grasp the shaft coupler and turn the shaft to the second of the four switch positions.
Turn the detent shaft fully counterclockwise as viewed from the front panelif this has not already been done. Such an antenna will have low imped- ance and will reduce mannual changes of high RF voltages appearing on the Antenna Tuner or associated equipment.
With the exciter in either the tune or CW mode, advance the exciter’s carrier level or power output control for an on-scale reading on REF meter Ml. Tighten the setscrew only enough to hold the coupler in place. Place one of the Be careful not to over- tighten the hardware or you could damage the meter.
When you tune your exciter, be sure to observe the duty cycle limitations, if any, 3. Then tightly twist the wire ends and add a small amount of solder to hold the fine strands together. Position the capacitor assembly as shown in the Hewthkit. This completes the assembly of the matching capacitor.
Just start the nut onto the end of the screw; it will be tightened later. M Position the rotor and stator assemblies as shown in the Pictorial, Then push the rotor shaft through the bushing in the capacitor front plate as far as it will go. Then lower the spring over the end of the rotor shaft. Use the Parts Order Form furnished with the kit.
When the shorting bar is connected between connectors J 3 and J4, con- nectors J4 and J5 are usable for balanced or unba- lanced feed line antennas.
Use control hardware and position the control as shown in the Janual. Push the spring down and insert the tab of the spring into hole AP in the capacitor rear plate. Solder the lead to the eyelet. Squeeze out an amount of grease equal to a medium-sized pea; then use a toothpick and apply the grease to the rotor shaft at the three locations shown in the Pictorial.
Be sure in each step that the proper part has been wired into the circuit, as shown in the Pictorials.

Tighten the nut snugly. Discard the excess cable. Connect the end of the black wire to solder lug K NS.
When SW2 is at the REF out position, the power reflected through the transmission line from the an- tenna, dummy load, etc. If necessary, cut off any excess tape length. Then push the end of the sensor cable into grommet A and pull the cable through to take up all the slack.
Reinstall the nut on the feedthrough and tighten it finger tight.
