FAQ

Q1: What is the USDX SDR QRP Transceiver?
A: The usDX is a simple and experimental (Class-E driven) SSB and CW SDR transceiver. It can be used to make QRP SSB contacts, or (in combination with a PC) used for the digital modes such as FT8, JS8, FT4. This approach simplifies the design where possible while keeping reasonable performance. The result is a cheap, easy to build, versatile QRP SSB transceiver that is quite suitable for making QSOs, even in contest situations.

---

Q2: What bands and modes does the USDX support?
A: The USDX QRP shortwave transceiver operates in LSB, USB, and CW modes, covering the 40m, 15m, and 20m amateur radio bands. All-mode support includes USB, LSB, CW, AM, FM. It can be fully-continuous tuned through bands 80m-10m in the LSB/USB-modes with a 2400Hz bandwidth and has up to 5W PEP SSB output.

---

Q3: What is the difference between USDX-CW and USDX-FT8 versions?
A: The CW version supports LSB, USB, and CW modes but does not support FT8. The FT8 version is added with Bluetooth function. Through the firmware upgrade interface, you can update the firmware for USDX-CW or USDX-FT8 transceiver. Later, the firmware of CW and FT8 versions can be flashed for each other.

---

Q4: What are the DSP features of the USDX transceiver?
A: DSP filters include: 4000, 2500, 1700, 500, 200, 100, 50 Hz passband. DSP features include Automatic Gain Control (AGC), Noise-reduction (NR), Voice-triggered Xmit (VOX), RX Attenuator (ATT), TX noise gate, TX drive control, Volume control, and dBm/S-meter.

---

Q5: What is the frequency stability of the USDX?
A: Using TCXO, its operating frequency stability is up to 0.5PPM. Adopting KDS high-precise TCXO, the frequency accuracy and stability surpass similar products.

---

Q6: How does the Class-E PA work in the USDX?
A: The usDX uses pulse width modulation of the PA supply voltage to transmit modes other than CW while retaining class E efficiency and uses a direct conversion SDR receiver. The basic idea behind Class E nonlinear amplifiers is that transistors have little loss when they are switched fully on or off. A PWM driven class-E design keeps the SSB transceiver simple, tiny, cool, power-efficient and low-cost – no need for power-inefficient and complex linear amplifier with bulky heat-sink as often is seen in SSB transceivers.

---

Q7: How do I use FT8 digital mode with the USDX?
A: For FT8 (and any other digital) operation, select one of the pre-programmed FT8 bands by double press the rotary encoder, connect the headphone jack to sound card microphone jack, sound card speaker jack to microphone jack, and give a long press on right button to enter VOX mode. Adjust the volume to a minimum and start your favorite FT8 application (JTDX for instance). Users can experiment with FT8, AM, and FM using a computer or mobile phone via Bluetooth.

---

Q8: What is the receiver performance of the USDX?
A: Receiver noise level MDS: -135 dBm (200Hz BW) at 28MHz. Receiver front-end selectivity: steep tuning frequency -45dB / ten times roll-off +/- 2kHz. Blocking dynamic range: 20kHz offset 123dB, 2kHz offset 78dB. Three independent switchable analog front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB) are included.

---

Q9: Is the USDX firmware open source?
A: Yes, the USDX has open source firmware, built with Arduino IDE; allows experimentation, new features can be added, contributions can be shared via Github. It is optimized and modified based on the open-source work uSDX/QCX-SSB. The open source URL is: https://github.com/threeme3/usdx.

---

Q10: What is included in the USDX package?
A: The package includes the main unit, a power cable, and a hand microphone. A 12V power supply is not included.

---

Q11: Who developed the USDX transceiver?
A: The basic work uSDX appears to have been accomplished by Guido Ten Dolle PE1NNZ. It uses pulse width modulation of the PA supply voltage to transmit modes other than CW while retaining class E efficiency and uses a direct conversion SDR receiver. This has an interesting international development process with contributions by many, including Hans Summers G0UPL, Guido Ten Dolle PE1NN, Barbaros Asuroglu WB2CBA, Manuel Klaerig DL2MAN, and others.

---

Q12: What is the CAT data switch (Menu 8.6)?
A: Please turn off Menu 8.6 (CAT data switch) when FT8 is not used. When the firmware is for CW version, please turn off the CAT data switch in menu 8.6 to avoid the screen displaying incomplete frequency text. For FT8 version: Menu 8.6 CAT data switch should be turned on. At the same time, the radio in Bluetooth mode should be powered by the physical Bluetooth switch. In this way, the radio’s Bluetooth function can be used.
