Well, as for 599 +20 -signals I can only say that the whole LW and MW BC-bands were in the passband and same waterfall with you. I run the dongle in 2.4 Msym/s mode so can "see" 2.4 MHz in one screen. The only filtering I use is a simple 50 ohm LPF PI-filter with f -3dB at 15 MHz (The chip does DC-14.4 MHz). I tried this mostly for fun, but the cheap setup delivers more than I expected. BR P-H Quoting DK7FC <73dk7fc@googlemail.com>: > Uuh, thanks Paul-Henrik.
