Hello LF'ers, I would like to know if the experts here think I need an antenna attenuator on 136kHz? I am using in this capture a little IDC receiver: http://icas.to/lineup/idc-136-kit-eng.htm but see the same with a Softrock LF. I am unsure if the antenna is overloading the RX, it's a big file at around 14 megs, but I guess most people, unlike me in the sticks, have broadband :) Thanks. http://www.gatesgarth.com/Untitled26.mp4 -- Best regards, Chris mailto:dead.fets@gmail.com
