The ZEVS carrier seems to be still on.

Wow Edgar, that's impressive! SNR about 25 dB in 0.16 mHz, presumably on an E-field antenna? You might add another data point to Fig 2 in http://ee.stanford.edu/~acfs/82Hz.pdf , showing an antipodal focussing effect. Can you possibly calibrate the signal level? It may be interesting to observe a possible day/night change.

Best 73

Hi Markus,
