Oh, Darn, Now who am I going to dump on, when I "Rant" about SGC????
I wonder who their Chief Engineer is now? Maybe Finn Christiansen?

I usually bump into a few of their ham types at the Communications Academy
every year in Shoreline, WA. I will ask around this spring, April 2-3 I
think it is this year. See www.commacademy.org for info. I have gone 2 years
and consider it the best ham radio emergency communications training I have
ever seen put together. Last year the Canadian hams from BC really did a
super job on explaining problems and some solutions for forest fire
communications support involving hams on scene in both countries. It was
serious introspective critiquing, not the hype you see in the ham magazines.

My M710 predates the 2002 period. It was "opened" via a software
upload. Is it still Type Accepted? So far Bruce is either unwilling or
ill-equipped to answer this simple question.

All Icom M710 transceivers mfg. since July 2002 are a type accepted marine
transceiver that has the ham bands enabled by Icom. NO software uploads
required. No "opening" of the radio required. It is legal for the Marine
bands if you have a ships radio license and Restricted Radio operators
license, and legal for the ham bands if you have a general or higher ham
license.

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 Acceptance Proceedure, and different than the software
that was in the two submitted Representative Radios, then it is
considered a MODIFICATION by the FCC and would incalidate the
Type Acceptance of that radio when subsequently loaded in the radio
by ANYONE, even the OEM. The Radio isn't the same, when the different
software is loaded, unless that software was included in the Original,
or Subsequent Type Acceptance Proceedure by the OEM.

You can't modify the radio, in ANY substatial way after Type Acceptance
has been granted, and still have that Type Acceptance be Valid.

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 ;-)

Dear All

Does anyone have any experience/comments on the suitability of the Icom
IC-751...

I've seen several mentions of the Icom M-710 in this thread. If anyone
needs a IR-21 Controller for an IC-M710RT please email me.

This will allow controlling the radio from a second station and also act
as an intercom between the two stations.

This is new in the box with all hardware, accessories, and documentation.

Thanks,

Jack

Yep, that is EXACTLY right. This is a case where no Modifications are
made or needed, and Type Acceptance would still be VALID for this radio.

Not the case for most other "Opened" radios.

No, the M710 was resubmitted for Type Acceptance in 2002 with the new
software. Older M710's that require a modifcation would not be covered
by the newer Type Acceptance Certificate. Just confirmed that with one
of my old buddies in the Engineering Dept. at Icom America.

If the firmware upgrade, makes any Substantial Change in the Operational
Charactoristics of the Radio then the FCC does require a new
Type Acceptance Proceedure from the OEM. "Opening" a radio may
be considered a Substantial Change, and therefore could trigger
a resubmitted Type Acceptance Filing. This would determined by the
OEM in consultation with the Office of Cheif Engineer at the FCC
Lab.

Hello Bruce,

You must be a lawyer! I suspect that Doug was not
necessarily asking whether his older M710 is covered by the
newer Type Acceptance Certificate. I think he was asking
whether his older, open M710 is Type Accepted under *any*
certificate. This gets all the more interesting since I
believe Icom supplied the open M710s as an option and seemed
to claim they were type-accepted.

It is true that third parties and owners also opened some
M710s and it is an entirely different question whether that
invalidated the type acceptance. Let's stick with the M710s
that Icom sold as open first.

I understand your assertion that IF the early M710s were not
type-accepted in an open version, THEN the type acceptance
could be invalidated even if Icom opened them itself. What
has NOT been established is that there was in fact no type
acceptance of the early open versions. Can any of your
contacts shed any light on that question?


Thanks!

Chuck

Interesting. So my ICOM radio that was modified via an ICOM upgrade
is no longer Type Accepted and is thus illegal. Must be alot of
illegal radios out there.
