This Wiki is here to document and describe feature and functionality of the Vesper Cortex VHF Radio System for all owners of this piece of kit.

The official documentation is lacking. We intend to showcase user and non user system features that may be useful for your boat. Check out this namespace for all User Guides in this Wiki titled User Guides.

See namespace hacking for interesting customizations and other info.

Garmin (Fmr. Vesper) Cortex Marine VHF and AIS system. In 2022 Garmin purchaced Vesper Marine and with that, development slowed and shifted. Cortex system owners are far and few, but the majority seem to find the integration of VHF 2-way radio, AIS, WiFi, and NMEA interfaces compelling. However, the software is a bit lacking. We seek to unlock functionality original to the Vesper roadmap and beyond. Unlike the typical marine hardware from Garmin, closed source with proprietary interfaces, and very slow new feature development support, the Cortex was built with a relatively open stack of extensible software. The speaker mics handsets (the main user interface for this radio) seemingly runs a vanilla Android SBC and the interface to the Hub is standard WiFi Ethernet. With APK bianries available online. aka, Cortex Onboard, it's worth invensitaging what hidden features can be harnessed. With the holy grail of building a standalone Android App that can run all the features of the H1 and H1P handsets to a user hardware device, BYOP (Bring Your Own Phone)!

Wouldn't it be nice to have a H1P handset in your pocket. A handset that is actually waterproof and not full of terrible buttons that fail after a year out at sea? How about being able to stream the VHF radio audio to any device via WiFi Ethernet? Or do you simply want to read some sensor data that the M1 hub is captuing already and integrate it to your boat's SignalK network? The flaws of the OEM software and hardware should not stop us from utlizing the good parts of the system that we already own.
