Title: The AirSpyHF+ Discovery, Crossed Parallel Loop Antenna, and WWVB
Post by: ChrisSmolinski on August 23, 2019, 1504 UTC
I ran a fun test this morning, circa 1430 UTC. I connected the AirSpyHF+ Discovery to my 2m by 2m Crossed Parallel Loop Antenna, reference this post https://www.hfunderground.com/board/index.php?topic=38963.0

Note that the antenna no longer has a preamp and is now passive, and is on a rotor.

The combo does a great job of receiving WWVB and is quite directional.  I am about 1,600 miles from WWVB.

Inserting a 400 kHz low pass filter helps things a little, presumably that allows the Discovery to run at a higher gain?

Great video thanks -- I am happy to have the Discovery like others who have received it recently.   Hope to do some testing with it...
