I can try, but the pc that is doing the rx and the spectrograms already uses almost all of the cpu. Unfortunately i had to switch the clock to 800MHz, because of some problem with cooling. Maybe i will switch to doing the calculations and storage on another machine, but i will have to think of some reliable way to get the data there, that would survive a wifi dropout. > And what about Marcin?

Marcin SQ2BXI lives in the city too, also in a 4-story building, and also has a noisy location. We already had a wideband grabber there, and the S/N wasn't great. But it's a good idea to have a grabber there anyway, the more the better. I also want to try another location about 40km from Warsaw with two crossed loops (e-field won't work there because it's in the forest). Maybe that will be better. VY 73 Jacek / SQ5BPF
