| 1) Unscrew the bottom cover 2) Locate RV2 pot and turn to increase both modulation and TX power swing. 3) Find coil RFC5, and spread moderately to gain some TX power. 4) Locate L201, a sealed coil and core. Since the core cannot be adjusted, force 2 loops of the coil over the core to increase TX power. 5) Find L202 and compress this coil as much as possible to gain TX power. 6) Locate L203 and spread coil dramatically and bend into a semi-circular arc to increase its length. This will increase TX power. |
