JUCJET 5R Mini Support: App Setup, Bands, Software & Licence

The JUCJET 5R Mini is a pocket-size dual band handheld for licensed amateur operators: 5 W or 2 W on the 2 m and 70 cm amateur bands, 999 memory channels, two PTT keys with dual watch on a 1.44-inch colour display, programming from a phone app over Bluetooth, and a 1600 mAh battery with its own USB-C port. It is not a licence-free PMR446 or FRS walkie talkie. This page covers quick start, licence rules, bands, programming, realistic range, the questions we are asked most often and the accessories that fit. Different model? See the Support overview or the Download Centre.

Amateur radio – licence required. Transmitting on the 2 m and 70 cm amateur bands requires a valid amateur radio licence under the rules of the country where you use the radio. Air band and broadcast reception is listen-only. Want a set that works out of the box with no licence at all? See our licence-free PMR446 sets.

Quick start

  1. Charge first. The 7.4 V 1600 mAh battery charges through the USB-C port on the battery itself, from a wall adapter, power bank or car socket (wall adapter not included). The light is red while charging and green when full; charge between 5 °C and 40 °C with the radio switched off for a complete charge.
  2. Fit the antenna. Screw it on hand-tight only and never transmit without an antenna fitted.
  3. Set a frequency or copy one. Press MENU + 4 to switch on Wireless CPS, then pair the phone app over Bluetooth and set your channels there. Frequency Search reads a nearby radio’s frequency and tone so you can save it as a channel in seconds.
  4. Choose the power level. Output is 5 W high / 2 W low. Use the lowest level that does the job and never more than your licence and local rules allow.
  5. Listen and talk. PTT-A transmits on the upper channel and PTT-B on the lower one, so you can answer on either channel without switching first. The US version also receives 10 NOAA weather channels; these broadcasts exist only in North America. Press and hold PTT, wait half a second, then speak; release to listen.
  6. Everything else is in the printed user manual in the box. A PDF is not in the Download Centre yet – email ka@jucjet.com with “5R Mini manual” in the subject line and we will help.

Licence & legal use

  • The 5R Mini transmits only on the 2 m and 70 cm amateur bands. Transmitting requires an amateur radio licence (and, where applicable, a callsign) under the rules of the country where you operate. Check your national regulator before you key up.
  • Your version decides the transmit bands. The US version transmits on 144–148 and 420–450 MHz; the EU/UK version on 144–146 and 430–440 MHz. The version you receive matches the market you order from.
  • The air band is receive-only. Rules on monitoring aviation traffic differ by country, so check yours.
  • Programming 446 MHz frequencies does not make it a PMR446 radio. PMR446 is a separate licence-free service for type-approved equipment limited to 0.5 W ERP. For shops, events or a family holiday, use a licence-free PMR446 set instead.

Output power 5 W high / 2 W low Use what your licence allows

Amateur band edges and permitted power differ from country to country, so the ranges above are the radio’s capability, not a statement of what your licence permits. CTCSS/DCS is selective squelch, not encryption: it does not make a channel private or increase range.

Programming & software

  • Four ways to program: the phone app over Bluetooth (MENU + 4), PC software (CPS or CHIRP; programming cable not included – ask us which cable fits before you buy), Frequency Search, or the keypad. The PC software is not in the Download Centre yet – request the current file by email.
  • Do not install software made for another model on the 5R Mini.
  • Manual: the printed manual is in the box; a PDF is not in the Download Centre yet (see Quick start).

Range: what to expect

There is no verified, model-specific field-test distance to quote on this page. On 2 m and 70 cm the longest contacts come with an open, unobstructed line of sight; buildings, trees and hills shorten range, and a local repeater extends it. Antenna choice and position usually matter more than switching to a higher power level.

FAQ

Do I need a licence for the 5R Mini?
Yes, to transmit. Receiving broadcast radio and the air band needs no transmit licence, but check your local rules on monitoring.
Which battery do I have?
A 7.4 V 1600 mAh Li-ion battery with a USB-C port on the battery. We have no verified runtime figure, so carry a power bank for long days out. The radio is 108 × 52 × 37 mm and 200 g with battery, and has no water-resistance rating.
Can I transmit on the air band?
No. The air band (108–136 MHz AM) is receive-only.
Where is the programming software?
Not in the Download Centre yet. Email ka@jucjet.com and we will send the current file with the matching instructions.
How far does it reach?
Range depends on terrain, antenna and obstructions far more than on the power setting. There is no verified distance for this model that we can quote, so test at the positions you will actually use.
