ICOM IC-703
Product Code: SSB IC-703
Call for Pricing IC-706 LEGACY, NOW IN A QRP VERSION
Maximum portable convenience
 The IC-703 is designed for outdoor, portable operation. The optional battery pack, BP-228 provides 5W output power* and 7 hours* operating time. All the necessary equipment including
an antenna, can be packed in the optional multi-bag LC-156.
* 2W in AM mode.
* Tx:Rx:Stand-by=0.5:0.5:9 in SSB mode.
Built-in automatic antenna tuner
The built-in antenna tuner covers from 1.8MHz to 54MHz. Ideal for moving about during portable operation. Latch relays used in the antenna tuner greatly reduce the power consumption.
DSP capabilities
The built-in DSP unit provides noise reduction and auto notch functions.
* UT-106 DSP unit required for some versions.
