From Ashhar's post 18062:"The capacitor between pins 1 and 8 of the LM386 can be removed if you prefer headphones to speakers."
Check the LM386 datasheet if you want further info on this. Though I'd think if it were just an issue with audio gain, that could be cured by twiddling the volume control. ?Perhaps you need an RF gain pot going into that first RX amp at Q1.
