Hi Warren, LF/MF,

My LF/MF grabber is back since last night 22 UTC. Unfortunately thebrightnes settings were not optimal in the TA60 window so i had nochance to get a trace from you. This night it should work well. I hopefor some test signals to receive. Everyone is invited :-)

The LF RX now uses a 3rd order band pass filter (> 20 dB attenuation ofDCF39 and >60 dB for DLF (153 kHz)) and a SBL3 DBM. The 12 kHz IF outputstage is a LT1028. The front end is still the BF862 active antenna in38m AGL, but in a urban environment.
