An SWLing Post<\/em> reader recently contacted me with the following question:<\/p>\n

“What devices work well to cancel out local RFI? I’ve been told that both the Timewave ANC-4<\/a> and a number of BHI products<\/a> are all worth considering.”<\/p><\/blockquote>\n

Unfortunately (or fortunately, for me) I’ve no experience with outboard DSP or noise cancelling devices because I live in such an RFI-free area.<\/p>\n

I know this reader already has a Wellbrook Loop, but he’s looking for a way to even increase noise mitigation further at his home listening post.<\/p>\n

Post<\/em> Readers: Can you help guide him? \u00a0Please comment with your experience. Is a product like the Timewave or BHI the next logical step? If not, what is?<\/p>\n","protected":false},"excerpt":{"rendered":"
