Elecraft K4D vs. BHI Dual In-Line Noise Reduction

[@thuff3207]

I have not thought of using my BHI system on my K4. Thank you for showing this to the world.

I find just using the NR and RF gain control on the K4D does a really good job of eliminating background noise

would be nice to get this BHI Performance inside K4

spectral subtraction is supposedly coming some day after the remote thing is out when ever that happens. In the meantime that BHI box is impressive.

I use a ClearSpeech or BHI speaker or external filter on every radio I own that does SSB & AM including my ICOM 7610,ICOM 9100,ICOM 7000,& ICOM 703+. I HATE noise & I do what's possible so I don't hear any or as little as possible. I'm a believer in their products.
