TRX Board

This is a board from Dian Kurniawan (YD1OSC). BritX All Band HF Exciter with Audio BPF and 1 Watt TX preamplifier.  It is a design based on BITEX from Ashar Farhan.

I have take away the tx amplifier, I use my own design on the FrontEnd 02 board. Also take away the rx amplifier before mixer, then it works in/out to RF mixer.

Next mod is for CW I won’t sidton on audio if keying, so 12VTX to audio amplifier LM386 is taken from 12V to make it possible

I will son describe how I put all this together to a transceiver 1,8 – 52 MHz.
