#270 Retevis RB22 DMR Ham Radio Tear Down
Retevis has a new product RB22 Professional Semi-keyboard UHF DMR Radio:
https://www.retevis.com/rb22-professional-semi-keyboard-uhf-dmrl-radio-4000ch
Overview:
1. 1.77-inch color screen with semi-keyboard and removable antenna.
The large screen allows users to quickly view information and improve user satisfaction. This was the first amateur computer with a half-keyboard design. Although it was a half-keyboard, the combination of knobs could achieve the effect of a full keyboard.
2. Up to 4000 channels and 250 zones.
The 16 channels in one zone are standard factory frequency, and users can program channels and zones according to their own needs.
3. Recording.
Up to 200 hours of recorded calls can help you remember every important call.
4. It can meet the needs of hams as well as commercial use.
The RB22 meets hams' expectations for radio, while features such as a fall warning, remote stun and kill, etc, give commercial users another new option.
5. DTMF signaling.
Users can set and program the DTMF signaling via PC software to disable or enable some advanced function of the radio.

In part 1of this video we tackle a few tantalum capacitors that has gone dead short. We also have to replace a faulty
LM340T-12 regulator after checking the voltage rails. Just how many problems does this "Working EBay Find" have?
I am at a stand still till I do more research...
