All the receiver components easily removed have been removed
One helical filter has been left on the input to the Transmit amplifier chain
It has been fitted with a masthead preamp interface (5 pin XLR, supplied) which provides 28V (pin1) earth on receive (pin2) erath(pin3) 12v on receive(pin 5) all controlled by a PIC sequencer
No longer needed as I have two more powerful LDMOS 432MHz amplifiers
