Repair of the first unit is reasonable if you do the work yourself as the radio uses a common Mitsubishi mosfet which can be purchased at a reasonable cost (under $100).
The third unit is functional but seldom used. This is likely a fault in the oscillator crystal.
The second unit worked for a couple years then began to drift off frequency. As stated before, protection of the finals seems inadequate. This was due to an intermittent short in the antenna feed-line that was not apparent, making it not as much the fault of the radio but more the operator. One of the radios stopped transmitting correctly as the final amplification stage went out. Update: I've had three of these radios in the past three years. Tone squelch is useless on the primary radio in channel memory or VFO operation. Reception of a signal with a squelch tone on the primary does not break squelch, therefore, nothing is heard from the speaker. When option 3 is used, the tone squelch seems to work fine on the secondary radio (that which is controlled by the right display), however, the primary radio (on the left) it fails to function.
There is no option for tone encoded squelch without tone on transmit. Option 2 allows tone on transmit, and 3 is tone on transmit as well as tone squelch. In the menu, you can select under option 31 "Tone M" one of four options: 1) OFF 2) ENC 3) ENC.DEC 4) DCS. Tone encoded squelch does not seem to work on the primary side (left side) radio, however, works fine on the right side. If there is a spike in voltage during transmit then the final (MosFET) will fail. The PA stage gets very hot during transmit. This radio uses the same final amplifier transistor as does the Yaesu FT-8900R. The replacement part costs around $30 - $40 and can be replaced, with care, and good desoldering and soldering technique. Antenna failure during rain resulting in high SWR caused the Amplification MOSFET to fail in the radio. Protection of the final stage amplification transistor is present in this radio, but inadequate. The audio amplification is excessive for the internal speaker. I recommend using an external speaker unless you plan to keep the volume turned down relatively low. The speaker could not handle normal volume use. This is sold separately even though it is a counterfeit that TYT proudly stamps their name on.Īfter using this radio for several months in a vehicle, the loud speaker inside the radio burned out. The package did not include the TYT programming cable for connecting to a PC. Most radios have just the single inline fuse in the positive wire. Two on the positive red wire and one on the negative black wire. I guess you could run it from the cab straight through the firewall to under the hood, right past your battery and down the street to your neighbor's car battery. With all the copper we've shipped over to China in scrap, I guess they've decided to share some of it back. I have used a Baofeng programming cable with good results.

The programming software does work, but is crap quality. The cable that comes with it is a hacked bootleg knockoff that the Chinese cloned from the well known FDDI chip. You can program this rig from a computer using the special USB cable. Sensitivity on the receiver is very good. It also will receive from additional frequencies outside of the listed transmit range. The left side has all four bands while the right is 2m and 70cm only. The speaker is in the main body and not the detachable control head. The Yaesu requires modification for extended coverage while the Tytera does it out of the box. Although it lacks some of the refinement of the Yaesu, the Tytera model does allow you to receive AM modulation.
