| Power Tweek Modulation 1) Locate the middle leg of TR24. Cut the track going to this leg and bridge a 1.5k resister between them. 2) Change R126 to a 4.7k resister. 3) Change R124 to a 4.7k resister. 4) Re-tune L37 and L38 for maximum RF forward power. You can also remove R131 for increased modulation on AM, but it'll "garble" on SSB. VR1 RX Meter VR2 SSB Meter VR3 Squelch VR6 TX Meter VR7 Modulation Meter VR10 RF Power VR11 ALC Unlocking the Clarifier 1) Remove D52 and R44. 2) Remove R174 and place a jumper in its spot. 3) Follow the Red wire from the clarifier control to where it attaches to the PC board and unsolder it from the board. 4) Resolder the Red wire to the PC board ground. 5) Follow the Orange wire from the clarifier control to where it attaches to the PC board and unsolder it from the board. 6) Resolder this Orange wire to pin 3 of the MB3756 regulator. You should see about 5 khz of slide. (1 khz up and 4 khz down) 10 Khz Jump This mod is kinda tricky! It will not jump on all channels. The easiest way to give you both up and down jumps is with a SPDT Toggle switch. 1) Cut trace to pin 16 on the PLL. 2) Jump a 4.7k resister accross the cut you made. 3) Solder a jumper from center of switch to pin 9 on PLL. (8 volts) 4) One side of the switch goes to the cut side of pin 16 on PLL. 5) The other side of the switch goes to pin 18 on PLL. |
