Hi LF
As my PA is still down at home I can not leave it running at night due to the fan noise. So transmissions
are stopped at bed time here
Last night I used my 90m vertical antenna tuned for LF and connected to Perseus SDR for RX
The noise level is high but the teleswitch carriers are also high above the ground noise. So, not bad S/N
and much better than in MF
I have a big QRM from the elevators motors. They use 3 phase 380V frequency variators and the band
is whiped out with noise when elevators are in use. There are two in the building tower, but fortunately
not much traffic during late night hours
So, finally got 12 decodes of DC0DX. Signal report from -29 to best -20dB
I used EA5DOM/3 for this Rx setup. The software is last version of WSJTX
Locator is IM98WN. The other grabber and monitor Rx is at IM98XN using MiniWhip
This result is very encouraging. Great opportunities for trying QSO. No more “aligator mode” here

BTW: Seems that VLF signals are also quite strong. But elevators QRM may be a problem for long integration
