After adjusting a noise blanker on another radio, I decided to test K3's blanker. The captured screen from my Agilent oscilloscope shows the K3 blanker turned off (the captured waveform in the background) and with the blanker turned on (the active waveform) the pulse was reduced. The Agilent DSOX3024 has a built in wave generator configured to generate a pulse. The generator parameters are shown below. The oscilloscope's Ch 1 was connected to the K3's line out and ch 2 was connected to the wave generator using a BNC "T". The other end of the BNC was connected to the RX in port on the K3.
The pulse was adjusted for the worst case noise and the best setting for the K3's noise blanker under these conditions were t2-3. Don't quote me on this. I'm sure that other settings will work better for your conditions. http://elecraft.365791.n2.nabble.com/file/n6774838/blanker1.bmp ----- Jack WA9FVP Willco Electronics -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Noise-Blanker-tp6774838p6774838.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
