Alinco DR-620T Dual Band Radio

The Alinco DR-620T is a twin band mobile transceiver operating on the 2 meter and 70 cm bands. It has transmit coverage from 144 to 147.995 and 430-449.995 MHz. Receive coverage is 108 to 173.995 and 335 to 480 MHz. This includes the VHF air band in AM mode and the FM broadcast band 87.5 to 108 MHz in Wide FM mode. 200 alphanumeric memories are available. Power output on VHF is 50/10/5 watts and UHF is 35/10/5 watts. Dual band receiver with V/V and U/U capability (cross-band repeat is not supported). The large, easy-to-read three color (amber/yellow/orange) LCD shows status icons and alphanumeric tags. Other features include: auto power off, time out timer, tone burst, scan, channel lock-out, dimmer, VFO auto program, theft alarm function, narrow FM, power supply voltage display and remotable head. A fan on the rear panel insures cool operation during transmit. The front panel is remotable via the optional EDS-9 separation kit. The advanced 10F3 digital mode with speech compression technology is available via the optional EJ-47U board

The supplied EMS-57 Electret Condenser DTMF Hand Mic supports parameter setting and direct frequency entry. The radio also comes with DC cable, mobile mounting bracket with hardware, anti-theft (ACC on/off) function cable and anti-theft sticker.
