have you aligned the transmitter stages for max modulated output?
L47, L48, L46, L45, and L38. in that order.
do not touch L36. it is the TVI trap.

set VR10 for about two watts first. then, while saying "AHHHH" into the microphone in a steady normal voice, adjust these tuning coils for maximum output using a plastic tuning tool.
never use a metal tool to tune the coils.
then set VR10 for the deadkey you want.
If its a 148gtl, VR7 is your modulation control which should be set after you tune the transmitter.
