The NorCal S9 signal generator is a crystal-controlled oscillator which produces
switchable output levels at selectable frequencies. All of the board-mounted
components are included in the kit, all you need to add is a 9V battery.
Rubber feet are supplied for enclosure-free operation, or you can easily fit
it into an Altoids tin.
The S9 level is useful for testing and calibrating receiver S-meters while S1
level can be used for receiver alignment and sensitivity checks. The oscillator
works with most fundamental mode crystals, so you can substitute your favorite
frequencies up to 1 5m. The output harmonics also can be used to reach into the
higher bands.
The majority of the components are surface mount technology (SMT), but are easily
mounted due to wide component spacing. If this is your first SMT kit, be sure to
read the assembly tips section which will guide you to a successful assembly.
