This analyser is a high quality low cost DIY project which covers from 1.3 - 57MHz (160 - 6 metres). It is available in kit form only, and uses readily available through hole components. No surface mount components are used :-). It comes with full free backup. Below, you will find very extensive diagnostic data and if you really get into trouble while assembling and testing the analyser, email me, and together we will get it going.
To keep costs down, the overall controller is a pre-loaded 16F873A microprocessor. However, if you wish to play with the code and add other features, an optional Picaxe 28X2 can be substituted as controller, provided the crystal is also changed from 20MHz to 16Mhz. Note however that the Picaxe and crystal are NOT part of the kit, and must be supplied by the builder.
It features very high quality epoxy glass pcbs with plated through holes, an ultra rugged front panel finished with epoxy paint, and can be easily upgraded to cover the new 630 metre band (472-479KHz) by adding an extra coil. Only basic tools, and a good quality 40-50watt soldering iron are required for assembly.

Two photos showing the front and back of the main PCB when the Connector PCB has been attached with solder.
Using the Main PCB to drill the box lid.......... Note the careful centralising of the PCB, both horizontally and vertically, achieved by using the ridges provided just inside the edge of the box lid.
Using the Front Panel to Mark out the LCD Hole and 2 switch holes in the box lid.........Use the hole previously drilled in the lid top for the rotary switch shaft to accurately position the front panel.
Attaching The LCD to the main PCB..........This is the simplest way, but plugs and sockets are another method which can be used by constructors. Note the clip-on spacer on the front of the LCD, which ensures the LCD sits flat against the rear of the box lid. Also note the elephant hide insulation behind the LCD, ensuring that no contact can be made with the main pcb rear.
