Hello LF
Is there a s/ware package available to enable space diversity reception
using a stereo sound card, RH channel for one rx audio input and the LH
for the other rx input.
for instance a vertical ant and a loop ant input. Preferably visual
indication for each antenna and the option to select one or the other or
both.
I am building a square vertical loop ant each side about 20 metres  to
observe the difference on RX between a vertical and a loop. Going on
observations from signals used by others using a loop on TX, the results
are not as good as the vertical, but it would be interesting to check on
receive I have tried a 40 metre loop resonant on 160 metres and although
it is quieter than my quarter wave vertical the pick up performance is
not as good as the vertical, long range weak signals could not be heard.

For dx the low angle full size vertical is better than the small mostly
high angle loop.
The same probably applies to 73 and 136 khz.
