They worked ok if there were not other transmission with in the band with of there sniffers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I also use to use transceivers I had and a stepped attenuator to try and reduce the signal.  It didn&#8217;t really work too well if its super strong.  I tip I found was try and and direction find the harmonic of the signal as it way more reduced.  I could write and article to this.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another solution I had was a 2Mhz oscillator with mixer. Basically you use what ever receiver you have and tune 2MHz down or up to heterodyne the designer signal. the oscillator buffer would have a gain control.  this worker quite well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can buy direction finding radio or it  was expensive commercial stuff.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Being a ham we would  modify and receiver, A Tandy scanners was ideal with the bigger tuning range. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More to follow<\/p>\n\n\n\n<div class=\"wp-block-jetpack-tiled-gallery aligncenter
