I wish all my readers good health and good health! Today Master Sergei and I will be repairing the Jet mini radio, whose call button is broken. Such walkie-talkies are very convenient on hikes, so as not to get lost in the forest, during the construction of multi-story buildings, for guarding large warehouses, and so on. Jet mini has 8 tuning channels and provides half-duplex communication - this is when the walkie-talkie can either receive a signal or transmit it at one point in time. The mode is changed by pressing the PTT or button.

Let's get to know Jet mini better

The radio has 8 communication channels at frequencies from 446.00625 MHz to 446.09375 MHz, output power 0.5 W. The operating time from about 500 mAh is 20 hours, and the reliable reception/transmission distance is up to 3 km in the field. In urban environments, the communication range can be reduced to 500 m.

Disassembling the Jet mini radio

So, if the signal transmission button on your Jet mini radio does not work, that is, the red LED does not light up when you press it, as was the case with Sergei, then most likely there is a problem with the button or the board. Let's disassemble the Jet mini radio.

First you need to remove the battery and use an awl to remove the five rubber plugs on the back of the radio. Under the plugs there are screws that must be unscrewed. A latch awaits us at the top of the end of the antenna; we move it away and unlatch it.

Jet mini radio repair

After disassembly, we see a simple Jet mini radio device with a monoboard. The bottom button on the radio board turns the built-in one on and off and is rarely used. The top button on the radio board is responsible for turning on the signal transmission mode and is used very often, so the degree of wear is always higher than that of the bottom. It was the top button that became unusable. This occurs due to oxidation, debris or carbon deposits on the membrane contacts.

It is best to replace the faulty button, since many different types are sold in radio stores. But if there is nothing to replace the button, as happened in our case, cleaning the contacts with a contact cleaner spray or an eraser and alcohol helps a lot. The advantage of the spray is that it can penetrate non-removable buttons. For greater reliability, we desoldered and swapped the buttons.

Also one of the diseases is the keyboard of the Jet mini radio. Dust and moisture get on it and, as often happens in TV remote controls, the buttons begin to work poorly. When disassembling, it is best to clean them from dust with a brush and from oxides with a soft eraser and alcohol while the radio is disassembled.

After the maintenance of the Jet mini radio has been completed, we put everything back together and install the battery or three AA batteries.

Other problems with the Jet mini radio

The instructions for the radio have several examples and possible reasons faults:

1. There is no power - you need to check that the batteries are connected correctly and the voltage on them.
2. Poor signal reception - increase the volume or move closer to the signal source.
3. The reception/transmission channel does not change - the buttons do not work and need to be cleaned or the batteries are low.
4. Limited range - go out into the open to improve the radio wave propagation channel, and also check the battery charge.
5. The sound is distorted and hard to hear - the communication range is too long or the battery is low. You also need to check the antennas to see if they have fallen off.

Later, Sergei tested the radios in real conditions in a damp forest. The radios provided stable communication at a distance of 1200 m (!) in a straight line according to GPS readings. I’ll wrap it up here and wish you quick and easy repairs.

Master Sergei and Master Soldering worked hard for you.

I will agree with the above. From the fields from the hill to the center of the urban village from a distance of about 3 km, the signal passes with interference, in most transmissions the speech is unintelligible. Inside the same village, at a distance of about 1.5 km, you can’t hear each other at all. The batteries were fully charged. I expected more.
We use it for fishing - there are no complaints, but the distance between the radios does not exceed 500 meters. Soon I’ll take a Yaesu VX-6R or similar - I’ll check the quality of communication through it on Jets.

Advantages:

Long work from a set of batteries. One day I lost one of my radios. A day later, with the help of a second one, I found it in the grass, taking into account that it had rained at night.

Flaws:

Insufficient range of high-quality voice transmission.

Period of use:

more than a year

Brief description

Jet! Live is a compact PMR (Personal Mobile Radio) radio station that provides communication at a distance of up to 3 kilometers. The radio station has automatic noise reduction, scanning and channel monitoring modes, as well as a battery saving mode.

Design and controls

Sporty design, ergonomic body, compact dimensions– Jet does it all! Live is the ideal radio station for tourists and road trip lovers. Thanks to rubber inserts on the sides, the walkie-talkie does not slip in your hand, and the PTT (push-to-talk) button is located so that it can be pressed comfortably no matter which hand you hold the walkie-talkie in - your right or your left.

Next to the built-in antenna there is a headset jack and charger. The front panel has buttons for turning on the radio, menu, ringtone, channel scanning and monitoring, volume up and down. There is also a button to turn on the keypad lock mode, which will help you avoid accidental key presses.

The backlit LCD display is small and practical, angled and therefore clearly visible even in bright sunlight. In addition to the active channel number, volume level and transmit/receive icons, it also displays a battery charge indicator and icons for active scanning or channel monitoring modes. After the end of the transmission, when the PTT (push-to-talk) button is released, the radio station sends a short beep to confirm the end of the connection. This signal indicates that another radio station may be transmitting a response message. There is also a special button for calling a radio station - you can “call” your partner before you start talking.

Channel scanning and monitoring

By default Jet! Live operates in automatic noise reduction mode, filtering out static noise (such as air conditioning or highway rumble). You can disable this feature by switching to monitoring mode, which allows you to hear even very weak signals, which can be useful in difficult terrain. True, in this case you will also hear noise. It is worth paying attention to the channel scanning mode. In it, the radio station searches for an active signal sequentially on all frequencies available to it - you can listen to several channels at the same time or switch the transmission to the one on which at the moment there is a conversation going on.

Economical energy consumption

A nice feature of the Jet radio! Live is an energy saving mode. If you don't use the walkie talkie for 4 seconds, it goes into low power mode. This mode does not affect the transmitting ability of the radio in any way, but significantly increases the time battery life– from 12 to 20 hours. When you resume using the radio, it returns to full power mode.
