Lab599 has just announced that firmware v1.10.04 has been published for the Discovery TX-500 and is available for download on their website.
New: Audio modes
The new firmware adds two switchable audio modes: 1W “Normal” mode and 3W “Outdoor” mode. Although I’ve always felt the audio gain on the TX-500 was excellent, this will give even more granular control of volume levels.
New: Antenna SWR Monitor
Lab599 has also added an SWR monitor and display. They describe it on Twitter:
“This new function will provide you a graph to determine characteristics of the antenna (SWR) in the range of the selected band.”
They shared the image above of the TX-500 display and have already added this along with details in their downloadable user manual.

Apparently a terrific radio BUT “unobtanium” and thus I can’t get excited about “new features”.
Are any radios getting through to the US since the initial shipment? Curious.
Yes, HRO has distributed the TX-500 in a few batches already. I don’t know current status, though.
Just installed new firmware, works as advertised the swr graph is pretty accurate, checked it against Rig Expert and readings coincide. The only thing that changed with my settings, was the side tone had to be adjusted, it was lower level vs pre update level.
Mine is due to arrive today from HRO. My wait was about 3 weeks. Looking forward to using this radio.
