FTdx10 & IC-7300: Noise Blankers (Video #14 in this series)

My good friend Joel, KC4WZB, loaned me his brand new Yaesu FTdx10. When I say loaned, I mean he picked it up at Ham Radio Outlet and brought it straight to me, so I could unbox it and shoot a series of videos, exploring the capabilities of this latest offering from Yaesu. This is the fourteenth video in a series of videos I will be producing to show the capabilities of the Yaesu FTdx10. In this video we look at the noise blanker for both the FTdx10 and the ICOM IC-7300. A Noise Blanker is not the same as a Noise Reducer (aka Digital Noise Reduction). A Noise Blanker is designed to lock onto noise that manifests as repetitive pulses, such as power line noise or the noise generated by the motor in an automobile. The Noise Blanker detects the noise amplitude and timing, and counters it with an equal amplitude copy of the noise at 180 degrees out of phase. This effectively cancels, or blanks out the noise through a process known as destructive interference. It’s the same concept used in noise-cancelling headphones, though the Noise Blankers in amateur radios predate noise-cancelling headphones by decades. Note that most of the operating techniques I show and teach on my channel can be applied to other transceivers, even other brands of transceivers. Some knobs or buttons might be labeled differently but the function is the same. I have no allegiance to Yaesu. No manufacturer makes a perfect radio. They all have strengths and they all have weaknesses. I like to point those out. Yaesu thinks that I am targeting them, but I am not. In fact, they generally have the fewest weaknesses. It’s just that I want my viewers to know the good, the bad, and the ugly, so they can make informed purchase decisions. I am able to be objective because I have no allegiance to a particular manufacturer. My work is supported by private donations, via www.PATREON.com/N4HNH.

Without their support, I cannot bring my viewers uncensored content. Most videos are visible to Patreon team members long before they are released for public viewing. Some videos are never released for public viewing. S7 (Executive) and S9 (VIP) members who subscribe yearly have access to the menu optimizations guides I’ve written for the FT-891, FT-991A, FTdx5000MP, FTdx101D/MP, FTdx10, and FT-710 AESS. S7 (Executive) members who subscribe annually can request one menu optimizations guide. Annual S9 (VIP) members can request multiple guides, plus my FT8 configuration guide for either the FTdx10 or the FT-710 AESS. The guides are copyrighted.
