Galaxy Saturn problem

Hello again, started messing with this radio again, changed the voltage regulator and now the display comes on and it recieves bit only with the echo switch on, transmit just squeals through the speaker, flip the echo off and the display goes off and RX goes away
 
A look at the schematic reveals that the echo and the transmit input from the mike are not connected. Likewise the echo switch has no connection whatever to the counter display. The only way that switch can make a difference to the those functions is for something to connect them together.

Something that's not on the radio's schematic diagram.
