Adjust LOW power setting
The way to adjust low power is to regulate VR401. This trimmer can be found under the speaker (regulates power between 2 and 30 watts).

Adjust HI power setting
To regulate the power of the HI position is to adjust VR601. You can find this trimmer on the back left side (remove top and locate the alu cover).
Please be carefully when you dismount and locate the trimmer.

Adjust TX-Power/SWR ratio
At the same place you can find VR603 and that is the SWR protection control. Be carefull when adjusting this trimmer, because it protects your transceiver against bad SWR, but can be usefull when power drops to much on relative good SWR.

Adjust AGC
To adjust the AGC time constant of the transceiver locate VR402 that can be found on the left side at the center when removing the top.

Note:
Please be carefully with these adjustments! All modifications you make is totaly at your own risk.
If you have any other mods for this good transceiver then please contact me.
