HF TRANSCEIVER
This page will describe the construction of a multi band SSB transceiver.
Because I do 99% of my operating on my four favourite bands, I decided to build
a four band rig with provision for adding a fifth band later. The design can be
used on any band from 160M to 10M. Mine covers 80M, 40M, 17M, 10M.
SIMPLIFIED BLOCK DIAGRAM
This is definitely not a project for the beginner. I will only provide a
circuit diagram and a brief description of each part of the transceiver. The
construction details and choice of construction method, PCB, ugly construction,
Stripboard, etc, are left to the individual constructor.
