Introduction:

• 130*40mm Large DOT Matrix (264*64 dots) LCD display ensure excellent visibility-Night or Day. The newly designed 360 degree suction cup mounting bracket allows for superior suction and durability in the roughest environments. The bracket also allows you to remove the display for use or storage when required.
• 1000 programmable memory channels with CTCSS and DSC encode/decode DTMF encoding/decoding, priority channel scanning, and twin band simultaneous reception. It's bandwidth selectable, allowing you to select wide or narrow bandwidth at the press of a button. Bands can be freely set on the same channel for VHF TX-UHF RX or UHF TX-VHF RX. It's power selectable as well, with allowing you to select the output power to high medium or low.
• There's more 8 colors LCD backlights for selection, you will be safer because you can freely adjust the brightness of the backlight and button light, as well as automatic backlight setting. The stereo speakers built in the panel helps the automatically identify the signal. The speaker sounds simultaneously when received single signal and it sounds respectively when received dual signal.
• The optional GPS/APRS, Bluetooth BTG-6600A1, it can be wirelessly connected to your cell phone by Bluetooth, then the data of APRS will display on your phone, including the MAP, Call Sigh, Date Time and Distance, etc. Note:(This Item Not Include BTG-6600A1)

• Large, Fantastic and Easy-to-Read Liquid Crystal Display (LCD)
• Control Head Separation with Ease
• Built-in Three Speakers
• Cross-Band Repeater(X-Repeater) Capability
• 1000CH Huge Memory Channel Management Capability
• 50W Powerful and Reliable Output Power
• Built-in stereo decoder for FM Broadcast: Listen to FM Broadcast in Stereo with dual speakers on the rear of the control head
• DTMF Microphone Included
• High-speed Band Scope
• Wideband Receive, Continuous reception for short-wave, FM/AM broadcasts, aircraft, and public service channels ect.
• 8 colors LCD backlights for selection, you will be safer because you can freely adjust the brightness of the backlight and button light, as well as automatic backlight setting.
• Timer function: clock with event timer function to count up or down function etc.
• VR-6600PRO has the DOUBLE RF MOSFET MODULE, and it can provide very smooth power from the V band to U band.
• The hands-free function is realized with the mini-microphone built in the panel.
• Clear Voice: The stereo speakers built in the panel helps the automatically identify the signal. The speaker sounds simultaneously when received single signal and it sounds respectively when received dual signal.
• The newly designed 360 degree suction cup mounting bracket allows for superior suction and durability in the roughest environments. The bracket also allows you to remove the display for use or storage when required. All without the use of permanent mounting screws.
• The installed dual speaker enables you to freely choose the microphone connectors whether on the mainframe or panel.
• The mainframe is solid and break-resistant. Passive cooling adopted, the longevity of mainframe will not be affected by the dust absorbed on it.
• A Mini-Din Date connector is uniquely installed in the mainframe.
• Three speaker systems (two in panel and one in mainframe) allow you to have more options.
• Frequency: 136-174&220MHz 1W (USA only) &400-480MHz
• Output Power: 50 Watts (220 MHz 1 Watts)
• Wideband Receive
• NOAA Weather Channel
