Fantastic MW DXing tool  Time owned: more than 12 months
I've used Gerry Thomas's excellent Quantum Phaser for many years. I like it so much I've even bought a few as gifts for other radio friends... and they immediately loved it too!

It does exactly what it is supposed to do -- help null unwanted signals, peak others, search for other signals underneath stronger signals, etc..

Of course it does not do so automatically, it requires user control, but in this regard it is much easier to use and tune than the MFJ 1025/1026 phasing unit.

Finding and maintaining a good, deep null is fairly simple, and reliably so, time and time again.

It is made with care and quality parts by Gerry Thomas, who designed it after many experiments with other types of phasing circuits. He also utilizes some design particulars from well-known DXer Mark Connelly, by permission of course.

It's light weight, about the size of a paperback novel, and should fit on any radio table without any issues.

You will need to have two good antennas to use the phaser -- one for the main antenna signal and the other as a noise antenna. They should both 'hear' the same signal with the same strength, in order to truly null that station or remove noise.

I have used numerous different antenna combinations -- two randomwire/longwires, longwire and air core loop; a longwire and ferrite/active loop (Thomas's own Quantum Loop V.2); two loops; two verticals, a vertical and a longwire, you get the idea -- and in every case the unit works as it should, easy and quick.

For $135, this is one hell of a tool for the DXer and you really can't go wrong when you deal with Gerry Thomas -- you know right away he's just as much into radio as you are, and he is very good about answering emails and questions in a very timely manner. I've had a few questions over the years and he has never been anything but helpful and courteous.

Really... you can't go wrong.

Product is in production.
