In stock




Somehow, I become the owner of the US stock of TX-500s, but at a steep markup, so just adding a bit more to cover the postage and handling, and don’t know how long this will last.  Shipping is free in the US, but there are extra charges for international orders.  TX-500 verbiage below…

Ultra-compact transceiver

Lab599 Discovery TX-500

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

The Lab599 Discovery 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 panadapter, for easier search for new contacts and evaluation of band conditions wherever you are, at any time.

Discovery TX-500 — 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 0.55 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

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.
