I asked an acquaintance to buy radios for work, before that I took UV-5R, but then I decided to take him more effectively, thanks to the coupon, the difference was not so great. That's what came of it ...
Made a purchase, asked the seller to pack it well, to which the seller pleased me, said that the radios would be sent from a warehouse in Moscow.
Gave the tracking number IML express and after 4 days, I already got them.
Characteristics from the seller's page:
Baofeng walkie talkies are shipped in such boxes
Inside is a walkie-talkie
Antenna labeled Baofeng U.V Antenna FM / 136-174 / 400-520MHZ
Docking Station and Charger
And also a lace on a hand and a clothespeg for fastening on a belt or trousers.
The battery has an input for charging 4.0 * 1.7 mm
I rang it, apparently there are no charging controllers inside.
Since The tester squeaked both at the inlet and at the outlet and at the charging socket.
I noticed garbage on the display in one of the radios under the glass, there is nothing to do, it is necessary to open it ...
The radio understands easily:
Remove the battery, antenna and power (volume) knob.
Twist the two screws (asterisk)
Unscrew the tweezers rings on the antenna connector and on the volume control.
We hooked and carefully pulled out the stuffing from the case, the speaker was soldered to the board, so we pull it without fanaticism so as not to tear the wires.
I turn over and see the inscription on the 5R ver 26 board, it's funny, but exactly the same boards are in Baofeng UV-5R, it was decided to open it to the end ...
We unscrew the remaining screws and screws, remove the display, unscrew the remaining screws.
We unsolder the central contact of the antenna jack and at the same time raise the board.
Overturn the board ...
There is nothing new here, except that there are fewer parts than before in UV-5R.
KDHM8F2K6 8 Bit Microcontroller
AT1846S Single-Chip Transceiver (transceiver chip for three bands, but alas, 200-260 MHz bands are not added to the radio)
Putting it in reverse order ...
The most important thing is to get the contacts into the connector, otherwise the power from the battery will not go to the board.
Also, when you turn on the radio, if you hold down and hold the number 3 on the keyboard, the firmware version BFS001 will appear on the display as in the UV-5R.
Battery capacity also does not meet the stated characteristics:
Differences from the UV-5R perhaps only in the case, the buttons that are made by a separate board (made in the form of films as the keyboard) and the number of elements on the board.
Unfortunately, I don’t have any instruments for measuring signals, but judging by the board, it is already possible to conclude that there are no 8Ws in it, which means that this is some new clone UV-5R in the new package.
UPD: Made a test of communication with a friend, a distance of 1.2km at the intersection of 12 houses.
The radio Wouxun KG-UVD1P was at a height of 2 floors
The radio Baofeng BF-UVB3 Plus was at the height of 6 floors.
Both walkie-talkies are 5W.
Best of all reception on Baofeng BF-UVB3 Plus was at a frequency of 433.000.
The transmission from Baofeng BF-UVB3 Plus was not heard on the Wouxun kg-uvd1p.
