The Lab599 Discovery TX-500 covers 160−6 meters amateur radio bands, all modes, with a maximum power output of 10 W. It comes with true desktop-radio features, like auto-notch, noise reduction, and RX/TX EQ. The transceiver has a built-in fast panadapter, for easier search for new contacts and evaluation of band conditions wherever you are, at any time.

Discovery TX-500 —
highly energy­efficient portable transceiver

For a portable transceiver, one of the important characteristics is the power consumption in the receive mode. TX-500 transceiver uses unique circuit solutions to reduce the current consumption from a 13.8 V source to 100 mA, which is a unique offer on the market. The highly efficient transmission path will also allow you to enjoy long battery life on the air.

Unique form-factor

The Lab599 Discovery unique form-factor allows you to operate from anywhere. The transceiver is only 30 mm thick, including knobs, weighing only 0.55 kg. Fold out the kickstands at the rear for use on a desktop or picnic table.

11 discrete RF bandpass filters

Discovery TX-500 has 11 discrete RF bandpass filters. The RF signal is only passed through one of the band-pass filters — any out-of-range signals are rejected.

Built-in panadapter

The transceiver features a built-in high-performance panadapter, for better search for new contacts and evaluation of band conditions — wherever you are, at any time.

Aluminum alloy body

The transceiver's body is made of durable aluminum by the method of precision milling, to ensure a unique shock protection and provide good heat removal from the output part of the transmitter.

Well shielded inner units

To achieve high sensitivity of the transceiver, separate functional units are isolated from mutual influence and external interference by partitioning walls installed in the device case.

Dust and liquid protection

Due to the liquid-protected housing and the absence of through-holes, spatter resistant plugs, encoders with sealing rings, the transceiver will work reliably in extreme conditions, giving you real pleasure from traveling.

The case is also covered with a layer of black anodizing substance, to maintain an attractive appearance for a long time, even during extreme operation.

The display of the transceiver is protected by 1 mm thick tempered glass resistant to scratches.
