The lab599 TX-500 Discovery is a general coverage transceiver with AM mode, which means it can do double-duty as a shortwave receiver.
If you’ve been following previous TX-500 posts, you’ve seen me take this near military-grade portable transceiver to the field. I’ve activated a total of 6 parks in 6 days with it and it’s been a load of fun.
At home, I’ve also been doing a fair amount of SWLing with it in the evenings. I have a pre-production model that doesn’t include all of the accessories that will be provided with the production model. I don’t have a good way to port the audio out of the transceiver for recording at present, but I have been listening to broadcasts in the shack using a simple battery-powered amplified speaker.
I made a short video demonstrating the shortwave listening experience with the TX-500. It’s not a deep-dive by any means, but I thought it might provide a little more context. Keep in mind, I recorded this with my iPad, so the audio is far from ideal.
In general, the TX-500 is a fine radio for shortwave radio listening. It has the sensitivity and selectivity even a demanding DXer would seek. The TX-500 has a very low noise floor and an effective RF gain for mitigating summer QRN (static crashes) here in North America. I wish I had the time to tinker with the audio and see what sort of fidelity is possible. I’m not sure I’ll have time to cobble together a connection to my station monitors before I need to send it on.
Speaking of which, I’ll be sending this TX-500 to Ham Radio Outlet within the next two days. If you have any questions about it, feel free to ask now!
