The Truth about (tr)uSDX and the QCX-mini: An Easy Comparison Guide

Learn the truth about two popular QRP radios, the TruSDX and QCX-mini, with three simple tests in this video. Understand the differences between the two radios and decide

Introduction:

The video compares two popular QRP rigs, the TruSDX and QCX-mini by QRP Labs, and conducts three tests to determine the difference between the two radios.

The tests include the silence test, the pain test, and the signal purity test. The video aims to provide a subjective opinion on the work of these two rigs without the need to be proficient in technical details such as decibels, microvolts, or dynamic range.

I found this video to be valuable because it provides a straightforward comparison between two popular QRP radios. The three tests conducted in the video helps understand the differences between two radios.

Linas, LY2H, the creator of the video, has a channel dedicated to amateur radio with over 13,000 subscribers. Linas shares his knowledge and experience in the field of amateur radio, provides tutorials, and reviews various radios and equipment.

Key takeaways from the video include:

  • The TruSDX radio produces far more internal noise than the QCX-mini radio.
  • The QCX-mini radio is quieter and produces fewer birdies than the TruSDX radio.
  • The TruSDX radio has a slightly better signal purity than the QCX-mini radio.

Here are the steps followed in the video:

Silence Test:

  • Connect both radios to a Bluetooth speaker with no antenna connected to either.
  • Both radios should be set on CW mode 200 Hertz of filter with the AGC off.
  • Listen to both receivers and note the internal noise produced by each radio.

Pain Test:

  • Connect both radios to a dummy load.
  • Increase the sound level on each radio and listen to the internal noise produced by each radio.

Signal Purity Test:

  • Connect a Tiny SA to each radio.
  • Tune the frequency to the signal generator and choose the frequency for the signal generator to transmit on.
  • Adjust the level to the level of S9 for both radios.
  • Listen to the signal on each radio and note the quality and purity of the signal.

Resources mentioned in the video include:

  • TruSDX
  • QCX-mini
  • Bluetooth speaker
  • Dummy load
  • Tiny SA

My best advice for beginners in amateur radio is to start with a simple radio and work your way up to more advanced radios. Always conduct tests and experiments to understand the capabilities and limitations of your radio. Join a local amateur radio club and seek guidance and advice from experienced operators.

FAQ:

Q: What is a QRP radio?
A: A QRP radio is a low power amateur radio transmitter with a maximum output of 5 watts.

Q: What is a dummy load?
A: A dummy load is a device used to simulate an antenna load for testing and tuning a radio transmitter.

Q: What is a Tiny SA?
A: A Tiny SA is a low-cost spectrum analyzer that is used to measure the frequency and strength of radio signals.

Q: What is signal purity?
A: Signal purity refers to the level of interference or noise in a radio signal.

Q: What is a birdie in amateur radio?
A: A birdie is an unwanted signal that is generated within a radio receiver due to internal mixing or local oscillator leakage.

Conclusion:

In conclusion, when comparing the TruSDX and QCX-mini radios, it is important to consider the internal noise and birdies produced by each radio. The TruSDX radio produces more internal noise, while the QCX-mini radio is quieter and produces fewer birdies. However, the TruSDX radio has a slightly better signal purity than the QCX-mini radio. Ultimately, the choice between these two radios will depend on the user’s specific needs and preferences, as each has its own strengths and weaknesses.

The DL2MAN / PE1NNZ (tr)uSDX: A Pocket-Sized 5 Band QRP Transceiver

Are you looking for a super compact, portable QRP transceiver for your BOTA, POTA or SOTA ham radio operations? Then read on and watch DL2MAN’s video about his (tr)uSDX non-clone QRP transceiver.

Introduction:

Since I recently got a Venus-Tech SW-3B, I had not paid much attention to the (tr)uSDX rig from DL2MAN/PE1NNZ until now. YES! I am a BIG sucker for QRP stuff and just had to add one of these pocket sized rigs to my QRP stable. So, I pulled the trigger and placed my order for an assembled rig with AliExpress. AliExpress was listed as one of DL2MAN’s Where to Buy recommendations.

The (tr)uSDX is a 5-band, multi-mode transceiver that packs an efficient class E PA and supports CW/LSB/USB/AM/FM. It covers by default 80/60/40/30/20m (alternative filter setups possible). What sets it apart from the tons of clones is that every unit sold has its own serial number. To download the firmware upgrade you must enter your serial number and call sign into the web site. Your unique firmware will then be loaded into the radio, and your call will be displayed on the screen.

Sharing DL2MAN’s video about his design, operation and features of his (tr)uSDX transceiver might be valuable for those who want to learn more about it or considering one of these pocket transceivers for themselves. DL2MAN has a bunch of videos about his design on his YouTube channel.

Key Takeaways:

  • The (tr)uSDX transceiver is a compact, portable, and powerful 5-band, multi-mode transceiver that supports CW/LSB/USB/AM/FM.
  • Each unit sold has its own serial number, and you can upgrade your firmware only by entering your serial number and call sign into the firmware download website.
  • The transceiver is easy to use, and you can change various options in the menus to suit your needs, such as TX drive and noise gate.


Step-by-Step Firmware Upgrade Process:

  • Go to the firmware download web site and enter your serial number and call sign.
  • Download your unique firmware file.
  • Connect your (tr)uSDX to your computer via a USB cable.
  • Open the firmware update software and select your firmware file.
  • Click the “Upload” button to start the firmware upgrade process.
  • Wait for the firmware upgrade process to finish.
  • Disconnect your (tr)uSDX from your computer and turn it on.
  • Your new firmware and callsign should be displayed on the screen.
