Introduction. As a radio enthusiast, I'm always looking for lighter, more flexible devices to better explore the joy of radio outdoors. Recently, I had the pleasure of reviewing the TX-500 Discovery QRP radio transmitter from the Lab599, and I would like to share my experience and views with you below.
The TX-500 is a product from the Russian manufacturer Lab599. lab599 is a company that focuses on the development and production of portable, rugged amateur radio equipment. theirsThe products are known for their advanced technology, compact design, and durability to adapt to a variety of environments。The TX-500 is a universal coverage, low-power, portable radio transmitter from Lab599 designed for amateur radio enthusiasts and outdoor adventurers.
The look and feel of the device
The TX-500 impresses with its refined appearance and rugged body. The aluminum alloy CNC body design makes it one of the most durable and sturdy portable amateur stations I've ever tested. The device is relatively small, lightweight, and easy to carry. The multi-pin connector on the body is smaller, but it's very easy to use.
Operational experience
To power up, simply connect three components: the power supply, the antenna, and the microphone. The TX-500 does not have built-in speakers, so the use of a microphone is required, but the microphone provided performs well in terms of sound quality and volume. This is a convenient solution for SSB operation, but if used for CW operation, a headset still needs to be connected.
The TX-500 gave me a very good experience in terms of CW operation. I made a CW paddle cable that connects to the device with a simple solder. Interestingly, the latest firmware upgrade adds a CW memory key feature to the TX-500, making it more flexible and easy to use. While there is a brief delay at the moment, I believe this can be optimized in a future firmware update.
Shortwave listening and SWL experience
The TX-500 is not only an amateur radio station, but also a shortwave listener. Its high sensitivity and effective selectivity make it an ideal SWL device. I found its low noise level and strong RF gain to be very helpful for SWL in the summer QR (electrostatic noise) in North America.
Weather durability.
The TX-500 is somewhat waterproof and weather-resistant, allowing it to be used in light rain, so I don't have to worry about weather changes anymore.
Conclusion
Overall, the TX-500 Discovery has provided me with a whole new radio experience. Its rugged design, flexible operation, and outstanding performance make it ideal for outdoor adventurers and amateur radio enthusiasts. While there is still room for improvement in some features, the lab599 demonstrates a commitment to continuous product improvement through continuous firmware upgrades. If you're looking for a radio that's perfect for outdoor adventures and excels in amateur bands, the TX-500 is worth an in-depth look.
