K3 2nd external RX antenna. Today's VK7DIK 80m index is 3...against 1 yesterday..

When using the K3  KVX3  RX ANT IN  and RX ANT OUT for the 50MHz preamp.  The lowband receive K9AY loop antenne had to be disconnected.  But i think there is a  work around for this problem. I now use the AUX connector to the K9AY for the 2nd receiver. When the SUB is switched in. The audio Left channel is the main and right is the sub. The AF SUB Volume control is balance control for diversity receiving over 2 different antennas.  The SUB can be switched to AUX or MAIN ANT. So if the sub receiver is locked to the main and the ANT is switched to AUX i can use the K9AY connected to AUX. For WSPR i need to set the recorder mixer ruler to the right to have only the loop audio or to left to have the main antenna signal. Or i the middle for a mix. Would be nice if the line in left/right audio balance was also controlled by the SUB -AF knob but it seems it is not. I did set the mixer line-in ruler to the right and than switch of the Loop and i see a level drop.  I did not see this level

low bands

T61AA at 160m  WSPR  did not yet copy me but  A45SWL did copy about same distance but little more south path. 6 times Steve  A45SWL  did decode my 5W until now only 1 decode by VK7DIK 80M  22:16UTC  very late again must have been daylight in Tasmania then. Propagation is deep deep down all bands.
