The Lab599 Discovery TX-500 is coming out soon. A lot has been said about that radio's use of weather-resistant proprietary connectors, but what are the actual connector types?
The antenna is female BNC, but the power, speaker mic and other connectors are all circular connectors with keyways and threaded retaining rings.
Searching around, I found similar-looking connectors under Amphenol 97 Series, SAE AS50151 and MIL-DTL-5015, but I can't find anything definitive about what Lab599 is using.
