Discovery TX-500 Transceiver


A new firmware available v.1.05.00

Information source: Added a voice recorder / player function

Lab599 Discovery radio tailored for adventure, for extremes,
for using in places unattainable before, with no sacrifice of performance or features.

  • Software-Defined Radio
  • General coverage receiver 0.5 — 56 MHz
  • Adjustable output power 1—10W
  • Digital Hi-Performance Filtering (4 recieve, 2 transmit)
  • 48 kHz Build-in HiSpeed Panadapter
  • I/Q Output

The TX-500 covers 160-6 meters, 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 pan-adapter, for easier search for new contacts and evaluation of band conditions wherever you are, at any time.

Discovery TX-500 Transceiver — portable

highly energy-efficient transceiver

In receive mode, current drain can be as low as 100 mA —a unique feature on the market. Transmit efficiency is also excellent, with improved battery life.


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 0.58kg. Fold out the tilted-feet 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

Toachieve 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

Thanks to the liquid-protected housing and the absence of through-holes, spatter resistant plugs, valcoders 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.
