I used to use at first the MFJ-1026 Noise Canceller/Phaser box in a reverse configuration to bring the RX only antennas in from the Beverage bank. With the RF sense switch there were problems with the leading edge on higher speed CW being cut. This was solved by using the forced 12 available from a small relay box in line with the amp keying line, as my Icom does not provide 12 VDC out on key down only 8VDC at a few mills. About a year later I purchased the RTR-1 by DXE and this is really the way to go. As Tom, W8JI pointed out on an earlier article on his website, there are several improvements that can be made to the MFJ unit to reduce the noise figure on the RX port but I just use them now to phase Beverages primarily for noise cancellation from unwanted directions. This may help in some circumstances but the tuning in the MFJ is very critical and not something you can do well during the heat of a contest during peaking mode. So I just set things up in advance for one path and two Beverages such as Europe but that to can change radically the longest distance signals which can shift here from 20 to 90 degrees at times depending on what is happening at the north pole.
