The internal temperature is measured in the beginning of every transmission and at once when
modem cools down. The carrier power increases with falling temperature so that at 88°C carrier
power goes to 10W, at 83°C to 20W, at 78°C to 25W and at 73°C the modem operates again
at the full 35W carrier power.
3.3 Protection of current
In case of a bad antenna impedance matching the current consumption of the Power Amplifier
may be too high. For this reason the maximum current is limited to 12 A. If the current tends to
increase over 12 A, the automatic power control decreases the power level until the current drops
under 11.5 A. LCD indicates the actual power level of the transmitter. A new transmission starts
always with the nominal power level. The power control scheme is applied only when the nominal
power level is 35 W.
