The Icom IC-2820H 2M/440 dual bander has all the features you would expect and some you would not! You get:  separate front panel, wideband receive, 3 power settings, built-in CTCSS decode/encode, selectable amber/green display, PC compatibility and 522 memory channels. V/V and U/U receive is available. The rear panel has two SO-239 antenna jacks to support diversity reception (two antennas required). The diversity function compares the receiving signal strength from two different antennas, ANT1 and ANT2, and automatically selects the strongest signal. This feature is useful when you are listening in a moving vehicle or the transmitting station itself is moving. The band scope function lets you watch conditions near the receiving frequency. Diversity receiving, for improved signal stability is available in 127 MHz, 136 MHz, 146 MHz, 375 MHz, 440 MHz and 500 MHz bands only (two antennas required).

The IC-2820H is D-STAR upgradable with the optional UT-123. Power output is 50/15/5 watts on 2 meters and 50/15/5 watts on 440 MHz. It is 9600 BPS packet ready too (6 pin DIN). This radio comes with full function backlit HM-133 remote DTMF hand mic, mounting bracket, power cord and spare fuses. Please note that the mic plugs into the body (not the head). Main unit size:  5.9 x 1.65 x 7.4 inches 3.3 lbs (150x40x188mm 1.5 kg). Controller size:  5.9 x 2.6 x 1.25 inches 7.4 ounces (150x58x32mm 210g). This model requires 13.8 VDC at 12 amps. This radio is supplied with both the OPC-1663 (11 foot) and OPC-1712 (3.9 inch) head separation cables. This radio is reviewed in the November, 2007 issue of QST.
