Suggestions for a good digital signal/function generator?
#31

Ron,

I do my alignments a bit differently than others by using inductive coupling to the radios, so how I reduce the output level when I find it's too high is that I increase the distance between the inductive coupler elements. I have the output of my generator fed to a scramble wound coil. I connect a jumper wire to the specified injection point, then drape the wire thru', over or beside the coil depending on how much signal I need. By doing that I can reduce the input signals to zero, even though the generator might not be able to.

I am sure that anyone could build a shielded coupler if it was necessary. I haven't yet needed it.

Caveat :: I mostly work on AA5, AA6 or lower end multiband receivers (like your HQ .... I had one ... loved it!)

cheers
