If I remeber correctly this is the same board as the Midland 77-882, I wouldn't waste the 1307....

But if you must, remove Q15 and RV2, R59 should be 1K, R58 should be 27-33K, and C81 should be a .022uf. you can try changing C94 to a 470uf or 680uf cap. These radios don't have a mic preamp circuit like most other radios so you need to turn the microphone up a bit more.

When tuning the output use a dummy load, modulate the carrier and tune for max RMS output. With a 1306 it is normal to have 4 watts swinging to 6 or 7 RMS and about 13 watts peak. I'm not sure what a 1307 will do.
