| Power Tweek and Modulation 1) Change final RF transistor to a 2SC1969. 2) Solder a jumper across D10. 3) Change C91 to a 33 uf 16 volt polarized electrolytic capacitor. 4) Re-tune L8, L9, L10, L13. If you only have access to a Radio Shack and want to still increase your power and modulation with minimum of parts, try this: 1) Cut D9. 2) Change R108 to a .47 ohm resister. 3) Change R76 to a 1k ohm resister. 4) Change R43 to a 2.7 ohm resister. 5) Parallel a 100pf capacitor across C62. 6) Re-tune coils L8, L9, L10, L13 for maxiumum RF forward output. |
