Step | Condition | Adjustment | Procedure |
---|---|---|---|
1 | Mode: RX AM Band: Mid. Channel: 19 | L8 | Set RF SSG on 27.185MHz, 1kHz 30% AM-mod. Adjust L8 for maximum reading on oscilloscope. |
2 | Same as STEP 1 | L7 L9 L11 L12 L13 L52 L3 L4 L5 | Adjust level of RF SSG to obtain 2V on AF VTVM then adjust coils for maximum reading on meter. |
3 | Same as STEP 1 | L8 | Adjust to obtain minimum difference between Ch. 40 and Ch. 1 |
4 | Same as STEP 1 | VR1 | Set the level of RF SSG to 100mV. Adjust VR1 for "5-9" reading on tranceiver meter. |
5 | Same as STEP 1 | VR4 | Set SQ on max. Adjust level of RF SSG to 1000mV, adjust VR4 so that the radio signal will apper on tranceiver. Set SQ on minimum. |
6 | Same as STEP 1 Mode: USB | L14 L15 | Set RF SSG on 27.186MHz. Adjust coils to obtain maximum reading on oscilloscope. |
7 | Same as STEP 1 | VR2 | Set level of RF SSG to 100uV. Adjust VR2 to obtain "S9" on transmitter meter. |
8 | Same as STEP 1 SQ: Max. | VR3 | Set level of RF SSG to 1000mV. Adjust VR3 so that the audio signal will apper on tranceiver |
9 | Same as STEP 1 NB/ANL: ON MID, Ch.18, USB | L1 L2 | Set RF SSG on 27.185MHz, 0% Mod., 10uV Level. Connect oscilloscope on D2 and adjust the coils to obtain maximum deviation. |
10 | Same as STEP 1 | L6 | Set RF SSG on 27.185MHz with 1 kHz deviation, 1000mV Level. Adjust L6 to obtain maximum. |
