Hat tip to Thom's SWLing Post:
NR-1 is a revolutionary Noise Blanker which is the product of two-years of development and extensive testing by Kostas sv3ora.
NR-1 works directly at the antenna. This has significant advantages over the classic noise blankers which work at the intermediate stages of the receivers. It does not require a second “noise” antenna for its operation.
Furthermore, it is not based on cutting-off of amplifiers, unlike common noise blankers do.
Because of these, the NR-1 is superior, compared tocommon internal Noise blankers of radios....

Kostas (SV3ORA) has a PDF manual, demo videos, etc. here:
* Remove that annoying noise before it reaches your transceiver.
* This is NOT a QRM-eliminator/X-phaser, it does not use a separate antenna and it removes noise from any direction simultaneously.
