I have just received my RX-888 and am using it on my wife's I7 laptop since my I5 cannot handle more that 4Mhz of bandwidth.
Here is a 16 MHz bandwidth snapshot form the AM broadcast band to 20 meters. The strong signal around 5 Mhz (actually 4.95) is a RTTY signal. The other strong signals are SW Broadcasts.
I just started to play with and and find it helpful to see such a wide spectrum.
Is there a way of controlling the gain because it is overloading with this wideband antenna? If not the next step is to insert my BCB filter.
