Hi there,

Anyone have one of these? Ive just bought one with no manual. What aux
antenna
should I be using and where should the aux antenna be located in relation
to my
main antenna.
Secondly, what is the procedure for tuning the gain,phase1 and phase2
controls.
Mnay thanks, John G0WPA


A Scanning Electron Microscope to eliminate QRM ???

Seriously, this must be something like the MFJ 1026, no?

I suspect it is.
With the common canceller:
The thing to keep in mind is that what you are doing is creating a null in
the antenna pattern. Therefore, your "sense" antenna must pick up enough of
the unwanted signal to do this given the gain and noise limitations of the
box. Also, one null is a minimum. There could be more since you have an
indeterminate phased array. Also, if you are trying to receive from the
same direction as the unwanted signal, you could have trouble as well.
