    DSPKR 10 watt DSP noise cancelling speaker:

    "Beforehand I couldn't listen to lower band HF radio due to plasma TV from two next door neighbours. That changed when I bought your product and now I can use my radio again, especially in the evening and when tv's are on."
    Ian McCallum

    "Unit works great, gets interference out very well. Would not be able operate my amateur radio at home location, I use a Kenwood TS450 HF Tansceiver"
    David Digweed VE3FOI

    DESKTOP 10 watt DSP noise cancelling base station speaker:

    “I have sometimes been a little sceptical about DSP noise cancellation, but this really does reduce noise very effectively without any annoying and distracting DSP artefacts...”
    RadCom Jan ‘14 review

    “Transformed the output sound of my TS-930S providing as clear audio to match current rigs.”
    Geoff Blore

    NEIM1031MKII DSP noise cancelling in-line module:

    "I found it to be very effective in noisy conditions on air. An excellent product"
    Dave Clench

    "The 1031 meant the difference between hearing HF signals and not hearing them. It has improved my HF operting no end and is excellent value for money"
    Stephen Slater G0PQB

    "Made it able to hear other ham radio users on HF and VHF that I would not have been able to hear without, this means I can have more contacts for my log book, also make using the radio more pleasureable to listen for longer periods"
    G Fullbrook
