Hello all,
In a recent rush to eliminate urban noise I bought an QRM eliminator.
The working principle is to null out signals by shifting the phases of
two antennas (one main/tx and one rx). I can see the effect sometimes,
but it is not the holy grail for all types of QRM. I still don't get rid
of the PSU/LED/plasmaish noise here, sometimes the S/N is a bit better
but maybe thats my inner impression to justify buying this thing.
Now, I do wonder how this differs from diversity receive, effectively
versus local QRM.
Note I have a 10m vertical as the 2nd ant, while the main ant is horizontal.
Any thoughts or hints ?
tnx 73 Gernot DF5RF
