1) Receive “R”
2) Connect Counter (AC-coupled) to Emitter of Q14. Best use analog scope with Y-
output
3) Mode “USB” adjust C61 to 10,69850 MHZ (X1)
4) Mode “LSB” adjust C66 to 10,70150 MHz (X2)
5) There may be some interaction so repeat 3 and 4 if necessary
6) Mode “CW” frequency should remain at 10,70150 MHz (“RX”)
7) Transmit “T”
8) Mode “CW” frequency should move to nearly 10,70000 MHz (not more than +/-
500Hz)
9) Mode “FM” frequency should move to nearly 10,70000 MHz (not more than +/-
500Hz)
10) Note: At “FM” and receive “R” there is no output of BFO
11) Mode USB: Set R41 for just a little bit above S=0 (S-Meter just moves) on S-Meter
12) Tune in weak signal at 145,000MHz just enough to move S-Meter to S=5
13) Tune L1, L6, L8, L9, L10 for maximum
14) Tune in signal 50Mikrovolt 145,000MHz: Set R40 for S=9
15) Remove steps 11 and 14 if necessary
16) Mode “FM”
17) Adjust R1 on Main board near FM-Unit to S=9
18) Mode “USB”
19) Transmit “T”
20) Mode “USB” with PA operating (jumper P11/J11); adjust R66 for best carrier
suppression
21) Receive “R”
22) Connect AF signal (2kHz, 10mVpp) to MIC-Input
23) Set “MIC GAIN” to center position
24) Mode “USB”
25) Transmit “T”
26) Adjust output power with R69 to app.8 to 10W
27)
Receive “R”
