I'm playing around with my MFJ 1025 (with some inexperience in these
With working principle in mind, I've found it not so useful..
I live in an urban environment where , with my half sloper (and ,with less
amount , with my k9ay) , noise floor into my radio is S 8-9 all day long.
MFJ device is working, in fact I'm able to null every heard signal to 30-40
dB down but...not the noise !!!
Unfortunately, I'm not able to identify noise, as it is an undefined noise
floor, same type of noise you hear S 1-2 into your receivers.mine is S9
..the difference is when you have to listen to a DX with S3 , you can
understand me .
I've built a 4 inputs antenna switch in order to select wich one to connect
to MFJ main and to MFJ aux, so in example I can receive with k9ay and sense
noise with sloper , or receive with magnetic loop and sense with k9ay or
other..all possible combinations.
Results are always poor, I have not a dimmer , a power line, a motor a lamp
(and so on) to null out, I have instead a noise floor to lower down 20 or 30
Probably MFJ is not the right device or I am wrong in using it..
So definitively I ask you a personal idea about argument and some useful
hints about how to fight problem.
