136kHz RX activity

In the last few weeks I've received 136kHz signals from several different countries and stations:

DK7FC/P     CW/QRSS
DF6NM     QRSS
G8IMR      WSPR
M0BMU    WSPR
PA0A    WSPR
SM6BHZ     WSPR

Certainly my receiving system is now up with the best since adding the tuned preamp. My main drawback is the TX/RX loop's directionality which reduces signal levels in a N-S direction. We just need a lot more stations active on the band, especially on WSPR.
