I call those extensions, not incompatibilities- The FT-817 also has
the same one.  Note that Pauli and I arrived at that connector
independently of each other.

It's apparently aimed mostly at VHF/UHF rigs for packet, and since
those larger rigs don't cover that market....  It is there on the
IC-746PRO, which does cover 2M.

There are VHF/UHF only rigs that have a compatible connector.  The
Kenwood 733 has one, with the 9600 connection, too, just like the ICOM
and Yaesu radios.  I have no solid information about any of the Alinco's.

That's pretty close to a standard.
