MFJ-1025 All mode QRM eliminator

 

 You can place a null up to 60dB deep on any type of noise and interference arriving from many single direction and wave angle. Wipe out interference and noise before it gets into your receiver!

 It works on all modes -- SSB, AM, CW, FM and data, frequencies from 1.5 to 30 MHz
You can instantly change from nulling to peaking a signal at a push of a button and improve weak signal reception!

Wipe out ... lightning crashes from distant thunderstorms, severe power line noise from arcing transformers and insulators, lamp dimmers, touch controlled lamps, electric drills, motors, industry process, TV birdies...

Strong local ham overloading your sensitive receiver? Cant copy your QSO? cast a deep null on him and literally take him out -- Interference much stronger than the desired signal can be completely removed without affecting the desired signal

You can dig out a weak station hidden under a powerful one on the same frequency!
Null out your local AM broadcast station. Underneath, you might find an exotic distant station on an island you've never heard of.

Prevent overload by cancelling noise before it gets into your sensitive receiver.

The MFJ-1025 and your antenna can electrically "rotate the array" while the antennas remain physically stationary ... adjust both direction and wave angle of null or peak.... change from nulling to peaking with the push of a button... ignore mutual coupling effects as phase and level are adjusted.


Use the MFJ-1025 as an adjustable phasing network. You can combine two antennas to give you various directional patterns and improve receiving signal levels.


Examples... two verticals become steerable array... your beverage antenna and your transmitting antenna can enhance weak signals...two parallel staggered. Beverage antennas can improve front-to-back ratio or steer nulls. 

To null, adjust amplitude and phase controls for minimum S-Meter reading or lowest noise. To Peak, push reverse button. use built-in active antenna or an external one. Has near constant amplitude phase control.
RF sense T/R switch bypasses your transceiver when you transmit. Adjustable delay time.
