[aprssig] TH-D7A Firmware Upgrade ?

[Geoff]

Hi,

I remember some time ago there was a program kicking around to upgrade the
standard Kenwood TH-D7A to the (G) variant...   But I can't for the life of
me find it anywhere.

Was this update a publically available upgrade?

I should have updated my radio years ago :)
