Running a ZachTek WSPRTransmitter 80t010 0.2mW into a MyAntennas EFHW 8010 antenna, tossed out my attic window and tied to a tree as a test drive. Over 24hr, I got 353 unique spots on all 7 bands. SNR down to -29 and drift typically 0. Distant from NH, USA as 16862km in southern AUS. Pretty good rig and antenna combination!
