ASSEMBLY INSTRUCTIONS

The following assembly steps are given in accord with the LEARN-AS- YOU-BUILD philosophy for Ramsey Kits. To the extent that is reasonably possible, parts are installed in the order of signal flow as depicted on the schematic diagram, with some discussion of the components whenever useful.

Because the AA7 is of great interest to people who simply enjoy shortwave listening and VHF monitoring, experienced ham operators should understand that our instructions are addressed to people for whom this may be their very first electronic kit project.

First Assembly Steps

Perform all assembly on a suitable surface which will not be damaged by hot solder. A cardboard box, cut so that it is flat tends to work well if you do not have such a surface conveniently available. Always use caution operating and storing a hot soldering iron. We like to live under a nifty motto here at Ramsey that we think you will agree with (or will come to agree with!). “A hot soldering iron looks just the same as a cold soldering iron.” Trust me... it’s true.

Since you may appreciate some "warm-up" soldering practice as well as a chance to put some "landmarks" on the AA7 PC-board, we first will install some "hardware" components, to make the up-down, left-right orientation of the PC board as clear as possible.

In ALL of the following instruction steps, our word "INSTALL" means to do the following:

•Insert the part, oriented correctly, into its correct holes in the PC-board.

•If helpful, gently BEND the part's wire leads or tabs to hold it into place, with the body of the part snugly against the top side ("component side") of the PC-board. The top side is the side that does not contain metal traces, but does have an outline of each part printed on it.
