4.2 Alignment Procedures
Some coils should be pre-formed before starting alignment to align easily. Also all the coils must be
checked whether they are in the right form, not distorted abruptly.
check the proper operation of the IC. If the current consumption is over 200mA, either IC, MOSFET
might seem to be damaged or there might be short circuit in the hardware. IF

Set the tuner to the highest channel of UHF band, frequency = 858MHz and then adjust L33 to
have Vt = 22.5 ± 0.3V.
Adjust L5 for VSWR.
For RF curve & tilt adjust L15 first, and depending on the result, adjust L16 & L18. For high-end
fine-tuning, adjust L14 a little bit. If the pre-formation of L16, L18 is O.K, we need to touch only
L15 & L14.
Sweep the whole band or selected channels, and do a fine tune once again if necessary.
Set the tuner to the highest channel of VHF High band, frequency = 442MHz and then adjust L32
to have Vt = 22.5 ± 0.3V.
Adjust L7 for VSWR.
For RF curve & tilt adjust L21 first, and depending on the result, adjust L22 & L24 a little bit.
Sweep the whole band or selected channels, and do a fine tune once again if necessary.
Set the tuner to the highest channel of VHF Low band, frequency = 157MHz and then adjust L31
to have Vt = 25.2 ± 0.3V.
Adjust L9 for VSWR.
For RF curve & tilt adjust L27(Main) & L28 a little bit.
Sweep the whole band or selected channels, and do a fine tune once again if necessary.
