The Ten-Tec Orion is well suited for diversity reception with its dual receivers flexibly assignable
to two tuning encoders and three antenna inputs.  My main intention for diversity reception was
to listen on 160M/80M in two directions simultaneously with different Beverage antennas feeding 
each receiver.

I've been pleasantly surprised with the results from early experiments and wanted to share some brief 
soundclips here.  These are mp3 encoded at a fairly low bitrate to quicken downloads.  The antenna source
for the left (main rx) and right (sub rx) channels are indicated for each clip.

In the two clips with ssb pileups, G3WXX and Ten-Tec Net, notice the pronounced stereo effect and how distinct 
signals remain in the pileup.  The Orion's AGC does a fine job of not "homogenizing" multiple signals, unlike 
many other modern transceivers (esp. FT-1000MP).  

If you have difficulty clicking the links below and playing the audio in your browswer, please right click
the link and choose "save as" to download the clip and play locally.  These clips must naturally be heard 
with stereo headphones (recommended) or speakers connected to the computer soundcard.

in this recording, I switch back and forth between stereo diversity and mono reception (Yagi) to allow you 
to hear the difference - who said a Beverage antenna was only good for the low bands?!

And one non-diversity recording
For about 30 minutes before sunrise on 5 February 2005, there was a rare and extraordinary opening on 160M from
Albany NY to Japan.  During this time, I worked 7 JA stations.  In the preceding 5 years, I only had 3 JA contacts
total on topband.  I later discovered that my logging program (N1MM Logger) had actually recorded short bits of these 
qso's, although in mono, not stereo.  Unfortunately I lacked the foresight at the time to make a stereo recording of
the entire time period since I WAS using diversity reception with NW Beverage and Inverted L.  However, I thought I'd 
share a (mono) excerpt of what the JA signals sounded like on this end.  It is uncommon to even detect JA sigs down in 
the noise on topband from Albany, but to experience signals of this readability was a truly rare occurrence.
