Default Re: Basic stereo FM signal generator

I dare say that by injecting two different frequency audio tones it would be quite easy to check whether the stereo decoder was doing it's job, and also you could check the stereo broadcast beacon was working in the presence of a pilot tone. The unit I have has a digital readout of the transmit frequency, and is frequency selectable so is quite a useful bit of gear. I have a decent signal generator but no way of producing a stereo broadcast for alignment. Wrapping the gadget in some tin foil may be a cheap and cheerful way to attenuate the signal, which I think is pretty low anyway on mine.
