Why would you use this combination?
I would not use this in a EOC or Club station with multiple operators, and the reason is... If someone changes or deletes some of the setup you are off the air until someone can get it back running again.
They need know how the setup is configured to get it back working again.
I doesn't have Node capability, so no Node support the Packet Network
It would be good as a personal station if you already owned a Yaesu FT-991A
If you are dedicating into packet then there is a better solution.
I would recommend a Motorola with a Kantronics KPC series TNC that supports a KA or K-Net node. That would support the Local Packet Node Network too.
