Today I made real video of Noise blanker performance and how FT-DX10 and RGO ONE fight against strong pulse spikes. Side by side comparison. Tried best values for NB parameters for both radios. Signal mix is routed via coaxial switch
Noise blanker (NB) operating and installation guide
New firmware version 2.40A – Noise blanker functions added
This software version implements new optional NB module features.NB noise blanker/noise receiver optional board gives ability to remove pulse noisesfrom man-made home/industrial appliances, electrical power lines etc.QRN and other atmospheric noises with long pulse duration might not be suppressed effectively.

RGO ONE fights strong pulse spikes – youtube DEMO
RGO ONE Noise Blanker (noise receiver) demonstration. Input noise pulse spikes are simulated by Siglent arbitrary waveform generator. Frequency 14MHzPulse signal duration 80 periods (sinusoids)Silence duration 100 mili secondsInput amplitude 0dbm (>600mV) In other words injecting at receiver input very
