Contact author: Bill

Want to increase the TX power of your IC-7000?

DO THIS AT YOUR OWN RISK!!!!!!!

Build an adjustment jig plug by taking a 2-conductor 3.5 (d) mm (1⁄8″) plug and short the
tip to the barrel.

Enter the adjustment mode

Turn the transceiver’s power OFF.

Connect the JIG plug to the [REMOTE] jack on the rear panel.

While pushing and holding [P.AMP/ATT] and [TUNE/CALL], turn the transceiver power ON.

Enter TX adjustment mode. : Push [F-2 (TX)]

CAUTION: Connect a dummy load to the antenna connectors during the transmitter
adjustment.

Pushing [F-2 (TX)] until you see on the display PO MAX (HF)

Adjust the power using the dial (VFO)

Press F4 (SET) to accept.

The same can be done for

PO MAX (50 M)
