Before realignment, the cause of the fault must be determined and corrected. In-Line Wattmeter (accurate at 170 MHz) The small size of the FT-411 makes it difficult for Dummy Load (50-ohm, non-reactive at 170 the average operator to service. For this reason,...
Set up the test equipment as shown above for receiver alignment. RF Signal Oscillosc ope Generator With the transceiver and signal generator both tuned to the center of coverage 1 45 or 146 Millivoltmeter MHz), inject a 1 kHz tone with ±3.5 kHz devi ation at 40 dBu to the antenna jack.
