FT-817 Interactive Frequency Reader - current consumption

Measured on the FT-817ND 12Vdc input, the I.F.R. draws:

• nominally about 16 mA
• about 110 mA when communicating over the CAT interface

These measurements were taken without LCD backlight.

Since the circuit uses a 78L05 regulator, rated at 100mA continous, I would power the LCD backlight directly from the 12Vdc line, or a dedicated battery.
