2820H VHF/UHF Dual Band Field Programmable Mobile Radio

 

With optional UT-123 Board

Quality analog fundamentals, futuristic digital capability now!

 

Note: You will need an antenna that's made for the frequency that you need to transmit on. Also, your antenna mount cable will need to be terminated with a PL-259 (UHF Male) type connector for this Radio.

Wideband receiver with simultaneous receive capability

The IC-2820H receives 118–549.995 and 810-999.990MHz with dualwatch receiver capability that allows you to receive two bands simultaneously (including within a single band). Almost all VHF & UHF communications are available to you!

---

Diversity receive capability

If you have two antennas, diversity receive capability is useful for mobile operation where the received signal strength changes continuously. Within a single band, the radio compares signal strength from each antenna and chooses the better signal to maintain good sound and receive quality.

---

50W output power on both VHF and UHF bands

A MOSFET power amplifier provides a powerful 50W on both the VHF and UHF bands, making this compact rig’s signal travel for miles! Output power is selectable in 3 steps.

---

User-friendly operation

The large 93×28(3²¹/₃₂ ×1³/₃₂ in) mm full dot-matrix display presents an easy-to-read graphical interface, viewable over a wide angle. Push the “Function” button to call up the assigned functions menu on the display. In addition, tuning knobs and buttons for each band are arranged side-by-side, providing intuitive operation.

---

Separate controller from main unit

The controller is separated from the main unit for flexible installation. The controller has magnets on the rear panel, allowing y o attach the controller to the main unit or other metal objects. This makes clean and neat installation easy! A 3.4m separation cable, OPC-1663, and a short cable (10cm), OPC-1712, are included.

---

522 memory channels

The IC-2820H has a total of 522 memory channels, 500 regular channels, 2 call channels and 20 scan edge channels. Each memory channel stores tone frequency, skip information and so on. The Dynamic Memory Scan (DMS) system divides these memories into 26 groups, A to Z, and provides easy channel selection. Of course, bank scanning is also possible.

---

Band scope function

The band scope function lets you watch conditions near the receiving frequency and visually assists in finding other stations.

D-STAR digital voice + GPS receiver (With optional UT-123)

D-STAR DV mode + GPS receiver

The optional UT-123 provides D-STAR DV mode operation plus GPS receiver capability. Your location information can be sent simultaneously with the digital voice transmission.

---

Location information exchange

The IC-2820H sends your location information either when the mic PTT switch is pushed, or at a preset interval (5 seconds-30 minutes). When available from a calling station, the IC-2820H displays the distance and direction to the station.

---

GPS alarm

The GPS alarm alerts you by beeping when a preprogrammed point is within 500m or 1km range from your location or any one of preprogrammed points is within a preset square range.

---

GPS location tracking

When connected to a PC via the optional RS-232C cable, OPC-1529R, your own or the received location information can be plotted by mapping software on a PC.

---

One touch reply function

The one-touch reply function makes it easy to respond to a calling station instantly. In addition, up to 20 received callsigns are automatically stored as received call records.

---

Built-in voice recorder and auto reply function

The built-in voice recorder records an incoming call for up to 30-seconds (approx.), (or 15 sec. × 2 tracks, 10 sec. × 3 tracks). The 10 sec. transmit memory allows you to record your callsign or other message, and also automatically answers when you receive a message.

---

Low-speed data communication

When connected to a PC via the optional data cable, OPC-1529R, data communication is available simultaneously with a digital voice transmission.

---

DX communication over the D-STAR system

D-STAR repeaters for 144 and 440MHz are now available, allowing cross-band (144/440/1200
MHz) operation and long distance communication via the Internet over the D-STAR system.
