The amazing part is how the signals from the equipment in the back ground are separated from the signal of interest? With EbNaut? Regards, Edgar Moonah, Tasmania.
Hi Stefan, A small T Top antenna, 5 m long, 800 mm wide top (PVC tubes), ~ 3 m to ~ 3.5 m above the ground. There are 8 x 2 m radials on top of the ground, tied together at a 700 mm long ground stake
Hi Stefan, OK, first step is to see what signals can be received overnight from JXN and HWU. Images can only be uploaded once per day. Regards, Edgar Moonah, Tasmania.
Hi, Further conformation of reception of Kola Peninsula Transmit Facility signal at Moonah, Tasmania, over 15285 km. The following image is from DL0AO in Germany with sections of two images captured
Yes, Easily done with receiving antennas. The KPTF antenna here is 3.5 m high. 82 Hz wave length is 300 / 0.000082 = 3658536 m. Antenna height = 3.5 m = 1 / 1045296 of a wave length. Regards, Edgar M

Hi Stefan, Based on the past two days signal from JXN, would it improve the chance of detecting the carrier if the "FFT window time (length)" matched the time when the signal is at maximum? The FFT l
A successful transmission, on 17470.1 Hz, of a two character EbNaut message was completed on the 10 th September 2018. The transmitter was at JN49ik, Germany and receiver at QE37pd Tasmania a path of
Hi Roman, Luis, and Tim, Thank you for your interest in the EbNaut experiments. My contribution is small compared with Wolf, Paul, Stefan DK7FC and Markus Vester DF6NM. The first two gentlemen for pr
Hi Paul, Does the EbNaut receiving program look for a phase difference between the current symbol and the message start symbol, or look for the phase difference between adjacent symbols? Regards, Edg
