ATP-100 Instruction Manual

Caution: Be very careful to avoid applying full drive power to the PA

without having the load control open far enough. When power

amplifiers are undercoupled, tank voltages can be extremely high.

This may cause tank components, such as the bandswitch or

tuning capacitor, to arc and fail. It also stresses the tube and other

components with needlessly high voltages. The Ameritron ATP-

components.

Adjust the two front panel controls to a 10 o'clock position. With the amplifier

in stand-by, push the Carrier Tune button and adjust the transceiver's power

control to the rated drive power of the amplifier. Place the amplifier into operate

mode and depress the pulse tune button on the Ameritron ATP-100 Tuning

Pulser. Tune the amplifier for peak output power.

Note: Due to the response time of most non-peak-reading RF watt meters, the

meter will read a low average power, but the amplifier will be tuned for

full peak power.

While momentarily pressing the carrier tune button, the RF watt meter should

read full power of the amplifier. The amplifier is now tuned for full power.

For best linearity, it is best to reduce the transceiver's power slightly after tuning

the amplifier.
