Box above it is an AOR SR2000 Frequency Monitor. Guess what, it also has a type of spectrum analizer. Its display is currently not on the spectrum display but it can display a 10mhz spectrum section in a waterfall type display. Coverage is 25mhz-3ghz. To hear anything you have to connect a external speaker or hook it up to another AOR wideband reciever, but it's generally used to monitor and find radio transmissions by using the waterfall display.
Those white receivers look nice! What brand are they?
