Tune in the world where ever you go. The ICOM R20-06 has extremely wide coverage from 150 kHz to 3304.999 MHz (less 824-849 & 869-894 MHz cellular). Modes of reception include: FM, WFM AM, (SSB) USB, LSB, CW. This radio has two VFOs with dual watch capability. A built-in 32 MB IC audio recorder can record 1, 2 or 4 hours of reception (playback quality will be less on 2 or 4 hour settings). A total of 1250 memories are featured: 1000 regular, 25 scan edge and 200 auto-write scan. And this is Icom's fastest scanning radio at 100 channels per second in VFO mode. There are three types of priority watch: Memory Channel Watch, Memory Scan Watch and VFO Scan Watch. The R20 offers six forms of scanning. Scan resume can even be adjusted for 2 to 20 seconds or unlimited. CTCSS/DTCS/DTMF decode is built-in. The large two line dot-matrix LCD can be programmed for 8 character channel names.

You can see your signals with the built-in band scope. The sweep range can be selected from ±14 kHz to ±1400 kHz. Other advanced features include: Voice Scan Control (opens squelch only when a modulated signal is detected), Auto Squelch, Attenuator, key lock, RF Gain, Noise Blanker, ANL and AF filter. A built-in ferrite bar antenna improves medium wave reception. Weather channels and weather alert (USA version only) are featured. CI-V PC control compatibility is supported with optional CT-17. Simple PC programming and cloning is available via the optional CS-R20 software CD (with USB cable).

The special Set Mode Menu allows you to tailor many operational parameters to your personal taste including: Priority Watch, Key-touch beep, beep level, power save, NB/ANL/AF filter functions, AM antenna selection, scope audio, dial speed, etc.
