RX pre-amp details
The pre-amp is build around the AD8055AN Voltage Feedback Amplifier. W1FV is the father of this design. His design notes are writen down in a email on the topband reflector.
In Eagle we have made a pcb and its just a copy our the orginal design. The only difference is the connection to the ground rod an antenna where we moved them to the output/bottom side.
We add a option for a led as surgest by K1XX in case of trouble shooting.
