Stereo Headphones Required!

An example of diversity reception with a Ten Tec Orion transceiver. Using two antennas for receive, the Orion allows you to listen to both antennas at once and split the audio into left and right stereo. 

In this example, the left ear is hearing a 180 foot horizontal antenna. The right ear is listening to a 1/4 wave vertical antenna. You will be listening to the 40 meter Ham band in both the cw segment and the single side band (voice) portion of the band. You will hear me tune around the band for about 10 minutes of each segment.

Pay particular attention to how the signal fades from left to right ear (especially on weaker signals.) The fading from left to right is a result of the slow change in polarization of the incoming signal from horizontal to vertical. 

Single antenna receivers suffer fading effects since it will only hear one polarization at a time which causes complete loss of copy in some cases until the signal reverts back to either horizontal or vertical (however the single antenna is oriented.)

Enjoy! -W3ATT
