determined by the offset frequency.
➀
Push [VFO] to select VFO mode.
➁

Auto low power
When transmitting for 6 continuous min. at high power, the
IC-T7H automatically selects low power. This function cannot
be turned OFF and activates when the power supply is at ap-
prox. 11 V or more. To return to high power on transmit, select
receive, then switch back to transmit.
