2 INSTALLATION MECHANICAL HF SSB TRANSMITTER T2130 RETUNE PROCEDURE This is the tune procedure normally used. The conditions for a retune procedure are the following: - A frequency within the same 200 kHz band has been tuned previously to an SWR
2 INSTALLATION MECHANICAL HF SSB TRANSMITTER T2130 Each of the watched parameters results in a number of steps. The steps are simply added to the step found when the Automatic Power Setting was performed. act_step = APS_step + n1 + n2 + n3 Where: act_step = actual step for the attenuator APS_step = the step found at the Automatic Power Setting n1 = deviation step related to SWR n2 = deviation step related to Temperature n3 = deviation step related to Battery Voltage The subsections below describe each of the parameters watched. SWR WATCHING When the T2130 is transmitting, the SWR is continuously watched. This means in terms that the TXprocessor (3) measures the Rho approx. 2500 times per second. Note: Rho and SWR are two expressions describing the same physics. SWR - 1 1 + Rho Rho = ------------ SWR = ------------ SWR + 1 1 - Rho The measured Rho is compared to two limits. If SWR > 2.0 (Rho > 0.333) then a calculation takes place. The result of the calculation gives a number of 0.3 dB steps with which the RF-signal has to be reduced. The number of steps n1 is given by: (Rho - 0.333) * 18 n1 = ------------------------ (n1 cannot be negative). 0.3 If SWR > 5.0 then the error message ‘Bad SWR’ is generated. The operator is informed when the key is released. TEMPERATURE WATCHING The temperature at the power transistors in the Power Amplifier (1) is measured 4 times per second. The measured temperature is compared to two limits. If the temperature is above 98o Celcius a calculation takes place. The result of the calculation gives a number of 0.3 dB steps with which the RF-signal has to be reduced. The number of steps n2 is given by: Measured temperature - 98°C n2 = ----------------------------------------- (n2 cannot be negative) 2 This means that a temperature increase of 20°C to 118°C reduces the RF power approx. 3 dB. If the temperature is above 118° Celcius the Power Amplifier (1) is blocked and the RF-power is reduced further approx. 60 dB. An error message is generated and when the key is released the operator is informed. When the temperature has fallen to 100° Celcius the Power Amplifier (1) is opened again. 9315 PAGE 2-33
