In this video I try to describe only what this radio has in addition to the ATS120. The second half of the video shows how the radio actually works.

Pro's:
+ new improved original firmware (harduino.ru) with activated license key
+ large speaker
+ automatic internal SW/FM antenna switch
+ mobile radio form factor
+ 3000mAh LiPo internal battery
+ aluminum alloy box
+ large tuning knob
+ new 4 types of graphic S-meters (BAR, ANALOG, Audio-SPECTRUM, Audio-WATERFALL)
+ digital decoders for FT-8, FT-4, RTTY, CW, HELL (more will be added in the future)
+ functional RDS when receiving FM
+ indicator of the quality of radio wave propagation
+ receiver's system time synchronization via WiFi or RDS

Con's:
- additional LNA (preamplifier) is missing
- high pitch sound when the audio is muted when AGC is on
- reception of strong interference (QRM) from the screen when the internal antenna is connected directly to the BNC socket(telescopic whip)
