"Beforehand I couldn't listen to lower band HF radio due to plasma TV from two next door neighboours. That changed when I bought your product and now now I can use my radio again, especially in the evening and when tv's are on."
"Filters the noise and allows me to concentrate on what I want to listen to. Thank you."
"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"

"bhi have a proven pedigree in noise reduction and the DSPKR builds on this to deliver a particularly compact and powerful unit that works well in both mobile and base station applications. The very simple single button operation worked well and the facility to store your favourite setting helped make operation of the DSPKR a real breeze. Noise reduction performance was excellent with useful improvements available over a wide range of listening conditions. The noise reduction settings were particularly well chosen and all were usable under the appropriate conditions"

I noticed your advertisement in the October edition of Radio User magazine. After carrying out some research via you tube, I purchased from you the DSPKR, which arrived the day after ordering. ( ordered 04/10/2016). I carried out a test on Shanwick, 5650 KHz, and Volmet military, 5450 KHz, which from my location are radio 2 to 3 stations in terms of audio quality. The DSPKR increased the audio quality to radio 4 to 5 which in all honesty I was very pleased and surprised at. Random signals within the 6 MHz band with audio quality around radio 1-2 suddenly became readable with ease. I am delighted with the product and on that I congratulate your firm. The DSPKR has transformed my short wave listening hobby to a higher level. I use the DSPKR in conjunction with a Tecsun S2000 and a random length long wire antenna with a balun. I would highly recommend this product and personally consider it an essential piece of DX kit. Research source, YouTube, enter DSPKR, three short videos by Tony M0RIF, UK. Chris Williams UK
