Can I purchase just a power supply?

Hello, this product does not include batteries. Also we do not sell batteries separately.

Hello Is this a CB 27mhz tranciever? 10 meter? frequencies between 26.965mhz and 27.405mhz ? Its very unclear what this radio does. As so many is overrated in advertisings. For The Netheralands CB 27mhz are the free frequencies between 26.965mhz and 27.405mhz. Is this the right tranciever for that, Please?Sincerely R.Borgman

Hello, we are looking for a reply from our technicians. We will notify you when there is news.

where can i down load the operating system for this.

go to the Facebook uSDX page and you can download new firmware and instructions on how to load it.

Does it come with the battery?

hello friend it doesn't come with a battery

Some reference links：

it is optimized fromuSDX QCX-SSB open source hardware. The powerful software supports the use of less hardware to complete the SW transceiver and supports the SSB mode (reception quality is very good, transmission quality is slightly worse). In addition, the developer also developed an AM/FM mode for it, but AM/FM is defined as a gift function. Don't expect AM/FM too high.

Description:

This is a shortwave QRP SSB/CW transceiver. Ultra-small size is easy to carry to outdoor use, using 1602N LCD display

screen, built-in speaker, support to connect to PC, use FT8, JS8, FT4 and other digital mode software control, support CW automatic decoding.

Features:

8 bands covering 80m/60m/40m/30m/20m/17m/15m/10m.

Excellent PCB layout design that conforms to high-frequency circuit design principles to ensure excellent performance.

It can reach 3-5W power in 8 bands, and reserve SOT-223 and TO-220 package pads for upgrades

High emission efficiency, 80m/60m/40m/30m/20m efficiency is higher than 80%, 17m efficiency is higher than 70%, 15m/10m efficiency is higher than 60%

High-precision KDS brand TCXO, frequency accuracy better than 1PPM, frequency stability better than 0.5PPM

Ultra-small size: 83*38*124mm (excluding protruding parts)

Abundant interfaces (CAT, PTT OUT, MIC/KEY, K-head microphone)

All LPF parts use 100V C0G/NP0 capacitors

Use original genuine Omron magnetic latching relay

Use a lower noise op amp chip than the LM4562

Built-in speaker with cavity

BNC Antenna Interface

Specification:

Type: HF QRP SDR Transceiver

Mode: SSB/CW

RF output: 10W max at 13.8V exit DC in

Frequency range: 3.5-30MHz

Built-in Microphone

Antenna/connector: 50ohms/SO-239

Shell size: length 12.4cm x width 8.7cm x height 3.7cm (excluding protruding parts)

Packing weight: 550g

Packing size: 18 x 12 x 8cm

Function:

1. Simple, interesting and versatile QRP SSB HF transceiver with embedded DSP and SDR functions;

2. EER Class-E drives SSB transmission class

3. Use 13.8V power supply to output about 5W PEP SSB

4. Full mode support: USB, LSB, CW, AM, FM (SSB mode has good receiving effect, but poor transmitting effect. AM and FM mode are gift power, poor effect)

5. DSP filters: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband

6. DSP functions: Automatic Gain Control (AGC), Noise Reduction (NR), Voice Trigger Xmit, RX Attenuator (ATT), TX Noise Gate, TX Drive control, volume control, dBm/S meter.

7. SSB to sideband/carrier suppression transmit: better than -45dBc, IMD3 (dual tone) -33dBc, receive: better than -50dBc

8. Multi-band support, continuously adjustable through 80m-10m frequency band (starting from 20kHz~99MHz, performance loss)

9. Open source firmware, built with Arduin0 IDE; allows experimentation, new features can be added, contributions can be shared via Github, software complexity: 2000 lines of code

10. Software based Voice Trigger Xmit can be used as fast full control (QSK and half QSK operation) or auxiliary RX/TX switching to operate digital mode (no need CAT or PTT interface), external PTT output/PA control with TX-delay

11. Simple installation modification with 8 component changes and 8 wires

12. Lightweight and Low-Cost Transceiver Design: High energy efficiency due to EER transmitter class E (no need for bulky heat sinks), and and simple design (no need for complex balanced linear power amplifiers)

13. All-digital and software-based SSB transmitter stage: by controlling the phase of the SI5351 PLL (via a small frequency change on 800kbits/s I2C) and amplitude of PA (via PWM PA key shaping circuit)

14. All-digital and software-based SDR receiver stage (optional): Sample I/Q (complex) signal from quadrature sampling tester digital mixer and mathematically perform a 90-degree phase shift (Hilbert transform) in the piece and cancel one by adding sidebands

15. Three independent switchable analog front end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB)

16. Receiver noise floor MDS: –135 dBm at 28MHz (200Hz BW)

17. Receiver front-end selectivity: +/-2kHz steep -45dB/decade roll-off from tuned frequency

18. Blocking dynamic range: 20kHz offseit 123dB, 2kHz offseit 78dB

19. CW Decoder, Straight/Iambic-A/B Keyer

20. VFO A/B + RIT and Split, and corresponding relays via I2C with filter switching

21. CAT support (using TS-480 protocol)

Package included:

1 x Transceiver(not included battery)

1 x Microphone

1 x Charger (EU/US plug)

4 x Machine Feet

Product Safety Information

Setup Guide

Charge the battery pack

Insert the battery into the charger and plug in. Charge fully before first use — most packs take 1–3 hours. The LED will turn green when complete.

Insert the correct bit or blade

Open the chuck by turning it counterclockwise. Insert the drill bit or screwdriver tip and tighten the chuck firmly by hand.

Set direction and speed

Use the forward/reverse switch to set rotation direction. Select the speed mode (low for screwing, high for drilling) if your model has multiple speeds.

Adjust the clutch

Set the clutch to a low number for driving screws (prevents over-tightening) or to the drill symbol for drilling holes.

Use safely

Always wear safety glasses. Keep the drill perpendicular to the surface. Apply steady pressure — let the tool do the work.
