Dissipated heat: The dissipated heat in standby RX mode is typically 45 W depending on
attached ancillary equipment.
In transmit mode, use the consumption fi gures for the appropriate mode,
multiplied by 0.66.
E.g. 0.66 x 175 W = 115.5 W dissipated heat for a 150 W system in SSB
speech mode.
For a fi gure in kilocalories (kcal), multiply dissipation effect by on-time in
hours and then by 0.860.
For the 150W system, e.g. 115.5 W x 2 h + 45 W x 22 h (TX 2 hours + RX
22 hours a day) = 1221 Wh. 1221 Wh x 0.860 ~ 1050 kcal a day.
