7 Circuit Description Receive Signal Path Incoming RF signal is from the antenna jack is deliv- ered to the Main Unit and passed through the low- pass filter network consisting capacitors C1213, C1236.
8 Circuit Description TX APC Circuit A portion of the power amplifier module output is rectified by D1022 ( 1SS321 ), then delivered to APC Q1038 ( LM2904PWR ), as a DC voltage which is pro- portional to the output level of the power amplifier module.
9 Alignment Introduction The FT -1807M is carefully aligned at the factory for the specified performance across the amateur band. Realignment should therefore not be necessary ex- cept in the event of a component failure.
10 Alignment Preparation & Precautions A 50-Ohm RF load and in-line wattmeter must be connected to the antenna jack in all procedures that call for transmission; alignment is not possible with an antenna. After completing one step, read the next step to see if the same test equipment is required.
11 Squelch Threshold Level Inject a 435.100 MHz signal at a level of –14 dBµ (with 1 kHz modulation @±3.5 kHz deviation) from the RF signal generator . Rotate the SQL knob to the 10-o’clock position. Rotate the DIAL knob to set the alignment param- eter to “ 435.
12 CTCSS TX Deviation Rotate the DIAL knob to set the alignment param- eter to “ 435.000 103 435.000 103 435.000 103 435.000 103 435.000 103 .” Press the [ D/MR ( MW )] key to enable adjustment of the “CTCSS TX Deviation.
