My ICOM-M710 can be tuned off frequency on the Marine SSB
channels. Not sure why that might be type accepted but a ham rig
doing the same thing is not. That's the general logic from the folks that
told me that many hams rigs are essentually type accepted.

Hello Larry,

You might want to qualify that statement. Ham rigs tend to use finer
tuning steps in their VFOs than type-accepted marine radios (with the
general frequency transmit option) use in their VFOs, but it is just a
matter of degree. Both radios technically have VFOs that allow them to
tune between channels. As you know, there is absolutely nothing in an
"open", type-accepted Icom marine transceiver that would prevent anyone
from transmitting on any frequency covered by the radio. And of course,
there is the SGC 2000.

We probably need a more carefully worded statement of just what type
acceptance means in this regard (VFOs). Or are you suggesting that "open"
versions of the type-accepted marine radios are no longer type-accepted?

Regards,

Chuck

No radio with a VFO will get type acceptance for commercial use. It's

Type Acceptance is a "Legal Designation" that states that this particular
Radio Model has passed the required Testing and Design Criteria to meet
that requirement. This is done by the OEM, and they submit the results
of that testing, along with two actual production Radios to the "Office
of the Chief Engineer" for testing in his Lab.

"essentually type accepted" is an OEM's cop-out, for I don't want to
spend the MONEY it would take to get this model into compliance, and so
I just sell it into a non-Type Acceptance market, and save myself the
grief of proving that the radio is as good as I say it is.

Yea, there are a lot of the "Type Acceptance" spec that most ham radios
can pass, with no problem, but there are a few important ones that they
just can't make, because they aren't designed to make that spec. IMD
is one of these Biggies. Operational Control Design is another
requirement that keeps these ham radios from being acceptable.
