Zastone ZT-2R is a Yaesu VX-2R clone made by Shenzhen Zastone Technology Co., Ltd.

It is a very cheap AM NFM WFM wide band 0.5-999MHz receiver.
All accessories, service manuals, programming software and firmwares are 100% compatible!
Manual is written in the typical Yaesu style, and uses the word ‘VX-2R’ on a few occasions.

I ordered five times ZT-2R (one for me, 4 pcs for friends) and every time quality was perfect.

Frequency Ranges:
0.5-1.8 MHz (BC Band)
1.8-30 MHz (SW Band)
30-76 (59) MHz (50 MHz HAM)
76 (59)-108 MHz (FM)
108-137 MHz (Air Band)
137-174 MHz (144 MHz HAM)
174-222 MHz (VHF TV)
222-420 MHz (ACT1)
420-470 MHz (430 MHz HAM)
470-800 (729) MHz (UHF TV)
(757-774) MHz (UHF TV)
800-999 MHz (ACT2; USA Cellular Blocked)

TX Frequency Ranges:
144-146 MHz
430-440 MHz

Scanning Modes for All Occasions
50 Programmable scan edges
Preferential channels scan list
Over 1300 Memory Channels
Dual Band TX & RX
Ultra Compact, Perfect for EDC

Programming:
If you don’t like manual programming, all Yaesu cables and software will work.
VX-2 Commander is a best tool

Price is around $90, but it's currently out of stock.
Check AliExpress.com for current offers
I ordered it in official Zastone store

For more info check genuine Yaesu VX-2R reviews, discussions and user manual

Scanning speed: 11 steps per second
ZT-2R is a cheapest alternative to wideband scanners and transceivers like Kenwood TH-F7E, Kenwood F6A, Yaesu VX-3R, VX-6R, VX-7R, VX-8

Transmission range can be changed by software:
1. 144 - 146 MHz; 430 - 440 MHz = HAM bands only.
2. 140 - 174 MHz; 420 - 470 MHz = MARS/CAP mod. (Zastone default)
3. 120 - 221 MHz; 300 - 550 MHz = Freeband mod (checked and it really works on two Zastone ZT-2R)

Power supply voltage: 5,5 – 7,0V
Recommended power supply voltage: 6,1V
Voltage 9V will damage transceiver!

I want to share some of my files.
It is hosted on our HAM community site, because there I can easily update them
Wide frequency base CSV files (LPD, PMR, FRS/GMRS and more)
My currently used memory channels firmware

Programming Cable or this one from 409shop.com

Earpiece:


Genuine Yaesu VX-2R PCB, bottom side:


Repair and modifications:
1. Rubber covers for charger input and headset made ​​of hard rubber. You need to trim "rubber pin" a bit and rubber covers will fit much easily into their holes.
2 . I have one station without thermal paste between the output transistor and the chassis. Check or replace the thermal paste if you want to work on external power supply with x2 output power.
3 . Power button not works after some time:
Same, as issue 1. Power button is made of hard rubber. But in this case rubber pusher is shifted from button on pcb.
You can fix it with tweezers - pull the rubber to fit pusher and button on pcb.
4 . Flashing frequency on the screen means VCO failure (voltage-controlled oscillator)
During this issue reception does not work. This problem can only occur if ZT-2R used in the cold environments and can be fixed by replacing Q1069.
5 . Deafness on the first band (affects only 500 - 2000 kHz) can be fixed by replacing zero-ohm jumper by 120uH Ferrite Core Inductor (L1012 on PCB)
Marked with arrow:


You can buy additional cheap batteries:
FUJIFILM FinePix NP60 Battery - fits perfectly

Sounds to me like an out-right advertisement. I wonder if he's getting rep payment?
