For Sale, another Nokia Dolphin 432MHz Ampl

Post by G4FRE » Fri Aug 02, 2024 12:49 pm

Finally started to have a cleanout pre Bagington!

I have for sale a Nokia Dolpin 432MHz amplifier converted as per M0DTS instsructions

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

£60, collected at Bagington
