Out of interest, would it be legal if he put it in a box as
a plug in unit?

Yep, as long as the radio is not modified. The only external
device that is prohibited by Part 95 is an RF power amp.

That's U.S. rules, BTW.

As I expected :~)

Here in the UK, the use of power amps and pre-amps are
both illegal. However, as possession is not illegal, they
have to prove use.
The use of a SWR meter is only allowed while testing
the antenna.

External microphones could be a grey (or gray) area. The
radio is tested for approval, with the microphone that
will be supplied.
I believe that, if the manufacturer changes the microphone
supplied they must submit the radio for retesting - at a
very high cost.

But I see nothing in the rules about users plugging in any
replacement microphone they can get their hands on.

However, back to my original point...

His present method:
1. Is illegal.
2. Is only a board - putting off general CBers.
3. Is not as impressive to a CBer as a finished product.
4. Allows "screwdriver experts" to fekk up the
fitting and blame his product.
5. Has no way of proving "tampering", as the customer
is supposed to "tamper".
6. Allows less profit, with the extra going to
people, who may be wrecking the equipment.
7. Encourages "DIY" bodging inside radio.

What the potential customer is asking for:
1. Is legal.
2. Is "plug & play - CBer friendly.
3. Is a finished product and can look that way.
4. Ensures that only the manufacturer does
the wiring.
5. Can be warranty sealed.
6. Allows the manufacturer to make extra money
on the complete product.
7. Ensures the radio remains working as designed.


Yep, I can see why he decided to keep it as an
add-on board... You tell a CBer that the product
is legal, there's no way they are going to buy it.
:~)
