Many of you already know this,
I've been setting up the Orion in diversity reception for the past several
weeks,
Setting all the lights on under VFO A ( or B ) TX, RX and Sub RX
With a vertical to ANT 1 to the Main RX and a dipole to ANT 2 to the Sub RX,
Using headphones splitting the left ear to Main Rx and right ear to Sub RX,
Setting BW and PBT Track ON, Set AGC to PROG on both and set both setting
alike in the AGC, The AGC has to be set up as discussed, but for both
receivers.
All this sets up the diversity reception with nearly identical conditions,
It has helped me very much in weak signal copy.
Using this method, I've been able to make contacts that otherwise would
have been inaudible even with the Orion's Main receiver power.
The phase shifting between the two antennas is pretty rapid like a pulsing.
Copy is much improved because the audio is maintained in one ear or the
other and the brain keeps the continuity so copy is much better.
Hope this spurs some people to try it.
