Hi Paul, Probably you are the only one who is able to pick up the message that i will try to send soon. I'm not sure if your RX is running, i just give it a try. There has always been the question if

Hello Paul, VLF, Thanks for the results. The message '73' is correct! Well, i was unable to hold the antenna current constant on both frequencies, see attachment. Let's say the average current on 651
...i stopped the transmission and will restart with 30 seconds symbol length at 20:30 UTC. All other parameters are unchanged. I can also run plain carriers later, if of interest. But EbNaut messages

I ran my homebrew propagation model on the great circle from DK7FC in direction of Todmorden. Here's the received signal for the two frequencies, http://abelian.org/vlf/tmp/171017c.gif given 200mA cu
Here's the nighttime signal along the 88 degree bearing to Amberg, http://abelian.org/vlf/tmp/171017d.gif Quite the opposite to what signal reports suggest? The daytime signal on 88 deg isn't signifi
