MFJ-1026 deluxe noise canceling signal enhancer [RADIO]
See also:
Using a GRAHN antenna, (a VENHORST wire antenna for noise reference), the iCOM R8600 radio and optional bhi DSP audio noise canceling, trying to see what's the best way to cancel noise -- on the antenna entry point of the radio or at the speaker output end.
In this case the MFJ-1026 seems ineffective. The DSP at the audio output end works well and easy.
I have also tried two GRAHN antennas on the MFJ-1026, one for MAIN and one for AUX but that was also not noticeably effective yet.
I will also try the little whip antenna that MFJ supplied with the box. Further tweaking may turn out to be helpful on some other frequencies / signals.
Before installing the MFJ i used the little TECSUN H-501x to scan the room for any devices producing radio noise. It turned out that the two Apple Homepods sit in a dense cloud of radio noise, the Macbook Pro also radiates noise, EVE smart plugs controlling lights also produce radio noise, two little label printers s well and the HP printer/scanner too. So I moved those to the other end of the toom or to another room.
So far the MFJ-1026 does not do any harm and it looks good on the desk so as a box with buttons it is very pleasing in itself.
Glue Drool
The MFJ-1026 arrived with some odd tiny 'spider hair' inside over part of the circuit board. I checked with the dealer and they explained it's web threads left there by the glue gun that was used to fixate some parts on the board.
