Cut me some slack John. I've been an EE and SE for 30 years specializing
mostly in embedded systems. I know the difference between hardware,
software, formware and underware

Not all that clear. The ICOM M-710 is "opened" by uploading software
mods. Are you saying that if these mods are uploaded by the factory
or a dealer then it is still Type Accepted, but if I do it myself then
it is not?

BTW, your shift key seems to be malfunctioning. Better have it checked
by a qualified technician

Geeez Doug, What does it take for you to understand, here?

The software that is running in the radio, IS part of the Operational
Interface, and if it is different than what was submitted to the FCC
during the Type Acc

Doug,

Now we can start a ****ing contest. I've been an EE since 1969. Over 25
years in IT and worked in software development, communications as well
as sales and marketing!

You should know that based upon your experience the software that runs
a radio is embedded fiirmware. Very much tied to the radio hardware.
For example memory channels and translating stored frequency
information to the binary code to set frequency is one example where
the firmware and radio hardware are totally dependent upon each other.
Thus type approval must be for hardware and firmware at a specific
revision level. What would happen if the hardware were changed
significantly, you would need to redo certification or convince the
testing organisation that the hardware revision did not change the
radio specifications. The same should be true for the firmware that
controls the radio. That is just plain logical. Oops maybe I just
negated my thinking. After all when was a government agency ever
logical ;-)
