Yea, the propagation point is fair enough, but that's why there's a backup frequency
Shanwick asked the pilot if he could copy him and the reply was "Yes sir", but that was maybe 30 seconds - one minute before I was able to start recording.
Yep, it's an RTL2382U/R820T-based dongle, but the converter's a commercially available one - the NooElec "Ham it Up", and the combination of these is providing me with generally better results than my Eton E5 does - it's not as portable as the E5 though! A mate has the same setup (which is where I first saw it) and says his outperforms his Sony ICF7600 receiver. Cheap SDR it may be, but it's quite impressive. I just wish I could afford something like a WinRadio or Perseus
