This article describes measurement of an Icom IC-7000 current consumption during SSB telephony transmission.
The capture is of an IC7000 running 100W PEP with compression off. I have read copy as loudly and consistently as I could with barely a breath, so it is an overestimate of current consumption. There was small ALC deflection, but not so much as to effectively provide compression. Compression will draw higher current, depending on the level of compression. Note too, that like many Icom radios, the IC7000 draws a relatively high current key down with no audio (4.5A here).
