of the MFJ-1026 Phaser
You just have
to have one

numerous favourable reviews of the above unit, I was very
keen to lay my hands on one and when fellow NZ DXer Steven Greenyer
purchased one, I rang him to see what his opinion was.
Steven was very pleased with the possibilities the unit offered
and his recommendation was enough for me
US DXer Mark Connelly, had used one extensively and suggested
several modifications so after some another 'phone call to Steven
and some initial fiddling with the componentry, I set it up at
home and was pleased with some of the results I could obtain using
relatively short wires, i.e. one 25 metre horizontal and a 6.5
I could phase out semi-local 4XO 1206 just 100km away to reveal
Fiji and make a significant hole in local Radio Waitaki 1395 allowing
clear reception of NZers on 1386 and 1404 - with the phaser
off they were both splashed into oblivion!
I was very keen to get to my Beverage site at Waianakarua
and see how it performed with longer wires and the opportunity
came over our Labour Weekend holiday.
When I arrived and set up the gear, I was almost in too much of
a hurry to connect up the phaser but quickly realised that I had
all the cables etc to hook it up - that turned out to be
a great idea!
Now, I bought this thing to phase out pests and even after Steven
told me it was great for enhancing signals by adding the signals
from the two aerials required (in this case two 310 metre Beverages,
aimed at Florida, one terminated and one unterminated), I didn't
know how good I it was for enhancing signals until I tuned in
KCJJ 1630 and decided to use the phaser to try and remove the
CW from the Ohura aero beacon on the same frequency.
As soon as I switched the phaser on, and before I thought about
phasing out the beacon, I gained an immediate lift in signal and
the fact that both wires were directional towards the USA, meant
that I didn't need to phase the beacon as the resultant aerial
bearing was in the right direction for the desired station, and
about 60 degrees off the pest.
So once KCJJ was firmly in the bag, it was time to experiment!
Over and over again I was amazed at how I could deal to a pest
and clean up co and side-band channels.
I was initially sceptical at how well it would work on skywave
signals as past experience with the R-L-C type of phasers had
shown they worked well on groundwave but not too hot on the former
because of signal variation
To sum up just how well it worked on skywave: not only was I able
to get significant nulls on almost every NZer tried, I was able
to phase out KCCN 1420 in Hawaii and hear a mainland US station
running sports talk!
If you're a serious MW DXer, have access to long wires
or Beverages and have contemplated buying something to give you
an edge (maybe even a new receiver), you have just got to have
one of these!
NOTE: the modifications are necessary though anyone with some
experience with a soldering iron would find it relatively easy.
Also, there are two models, the MFJ-1025 and 1026, difference
being that the 1026 comes with an active whip input which is probably
not necessary, my recommendation would be to save yourself a few
dollars and get the MFJ-1025. The latter is also easier to modify
than the 1026 as it has standard discrete components rather than
the surface-mounted variety used in it's "big brother".
Lastly, a big "thank you" to Mark Connelly for making the modifications
public and encouraging MW DXers to get into this unit. Anyone
wanting details of these mods could contact me or check out Mark's
data at this web site.
