Re: [IRCA] Quantum phaser vs MFJ 1026

["W. Curt Deegan" <WWWR@xxxxxxxxxxxxx>]

I don't have the MFJ unit for comparison but I have been using the Quantum 
Phaser for a while now and do not see the signal degradation you seem 
to.  I can steer my antennas from one signal direction to another without 
any apparent signal loss, choosing which of multiple signals I want to 
hear.  Nulling one signal does not null others, with care the nulling is 
quite precise.

It may be a matter of antennas, no way for me to know, but I can say the 
Quantum Phaser definitely works for me, and I know others have spoken 
highly of the unit.

Craig, you posted earlier about the +/- switch causing loss of your "B" 
antenna.  If that hasn't been fixed then I would suspect any problems you 
are having are because of whatever is causing that.  That certainly is not 
how my phaser works.

I would suggest contacting Gerry Thomas at Radio Plus+ Electronics about 
these issues.  He is a MW DXer with a lot of experience, the designer of 
the Quantum Phaser and very helpful.
