Icom IC-R3 Wideband Receiver w/LCD Screen

What a cool idea this is! The new ICOM R3 offers incredible wideband coverage from 0.495-815.995 MHz and 902-2450.095 MHz in AM, FM wide, FM narrow and TV. Yes, the R3 has a built in 2 inch TFT color TV screen. (We sell the North American version that is NTSC format (not PAL)). You will be able to receive regular TV, but that is only the beginning. Imagine tuning to the VHF ham radio "fast scan" frequencies and seeing live ham transmissions. In fact with this coverage, you may be able to see all kinds of video links depending on your location! With an optional camera-transmitter you can even monitor video in your own house. The display can also be used as a spectrum bandscope (up to 500 kHz) and to display the various operational menus. There is also a second mono LCD display that can be used for conventional frequency display purposes when battery life is a concern.

The R3 is loaded with features. You get a huge 450 alphanumeric memory system (50 channels in 8 banks plus 50 scan edge memories), 4-step attenuator, video and audio outputs, auto power off, a 4 position joy stick and BNC type antenna. A tone squelch system is built in to provide quiet stand-by. Many frequency and memory scan modes are supported. The tone squelch includes two functions. The Pocket beep function alerts you with a beep when a specified station's signal is received. The tone scan function is used for the receiving signal such as for a repeater. This radio comes with battery, BC-153A wall charger, belt clip and BNC antenna.
