The 779  Weighs in at a hefty 14.2 oz (402g)
Chassis Size is  4.5" (W) x 1.4" (H) x 3.1 (D)"  (114 x 35 x 79 mm)

 
 
Frequency Range
 
144-148   420-450MHz
 
 
Enclosure and Mount
 
The main chassis weighs in at 14.2 oz with the entire chassis serving as a heat sink. There is no fan, but I found that the heat generated by this 20w radio is sufficiently dissipated as long as there is ventilation around the chassis.
 
The included bracket and hardware allows you to mount the radio in any position in the vehicle.
   
The front panel includes an RJ45 style microphone/programming jack, 6 illuminated control buttons and a volume control knob.
  Transmitter
 
I used my 13.8VDC power supply to power the 779 here on the bench. On the high power channels the transmitter put out 18.6W with low power coming in at 4.8w into a calibrated Bird Wattmeter.
 

High 18.6 Mid 9.7 Low 4.8

Receiver
 
The receiver's frequency range is 144-148  420-450MHz. With good sensitivity and plenty of loud/clear audio.
 
 
Microphone & DTMF Gain Controlling
 
The microphone keypad is illuminated for easy viewing. Along with the 16 button keypad are two buttons on the top for up/down channel selection.
 
Audio reports were excellent checking into the local GMRS net. The DTMF tones are distinct and loud. There is no audio gain control so I needed to speak about one inch from the microphone.
 
 
Channel Scanning
 
The radio's Scan function has a scan rate of approximately 10 channels per second.  Along with the traditional scan, there is also a Priority Scan option allowing you to select 1 or 2 channels as priority. he scan mode does not automatically restart at PowerOn, but two quick keypad presses and the start resumes.
 
 
Display
 
The 1.44" (3.7cm) high resolution OLED displays the channel name up to 8 characters on the upper half of the display while the secondary channel is below. The display clarity is excellent.
   
Programming / Cable
 
Software is easy to follow and the parameters that can be altered are the CTCSS/DCS tones an d the power levels on the upper channels as well as deleting and reentering new channel data.
 
The optional programming cable is a straight through USB to RJ45 that plugs into the microphone jack.
 
 
Build a K1 Programming Cable Adapter
 
If you like building projects, Michael (W7ML/WRBU527), has instructions on how to build your own K1 to RJ45 Cable Adapter. (Project Link).
 
 
Mobile Power Cable

The 4.5' (140cm) power cable attached to the back of the radio is terminated with a standard accessory plug. Direct connection to the battery is not required as the radio only draws 4A on high power transmit.


Base Station Operation
 
When running this radio as a base station, a power source of at least 6A continuous would be adequate.. A 10A supply would be more than sufficient. Here are a few power supply Examples that may assist.
 
 
Latest Update - April  2021
 
The original firmware did not allow changing CTCSS tones from the front panel. This has been corrected in the latest release of the firmware. Upgrade_w/Video
 
 
In Summary
 
AnyTone has put together a nice dual band mobile with the basic features needed for easy operation. The programming is simple and easy to understand, the display is clear, and has plenty power for around town use.
