Great, look forward tthe responses, as I am also a tinkerer

They work great in a boat.

If it is illegal in the US to modify a radio with an FCC, CE and ROHS approved kit then the regulations are ridiculous and smell of protectionism.
These kits are selling like hot cakes in the rest of the world.
Graham.

Well,, believe it or not this kit had nothing to do with the laws. They have been in existence for a very long time.

As far as our radios go, if it has a module in it you can plug any compatible module in, no issues.

You cannot swap a crystal in a transmitter or in a transmitter module to change frequencies.

You can swap a crystal in a receiver.

I do not think it has anything to do with protectionism. It has more to do with making certain that approved transmitters are not illegally modified.

[COLOR=#ff0000][COLOR=black]ASSAN CONVERSION KIT COMES WITH A FCC, CE & RoHS APPROVED 2.4GHz TX MODULE.

And I want to be clear that I am not referring to the module based systems. I am talking about the "hack" system where you open the transmitter and solder and remove parts, bypass parts and solder in the new RF deck. That you cannot do.

[G Doggett]

Bill

Correct me if I am wrong, but are you saying that in the US you are not allowed to change a plug in crystal in your transmitter to a different frequency, say from 27.045 to 27.145, if there is a clash with another radio ?
That is unbelievable.
Graham.

[SweetAccord]

That is good news..what range and any glitchiing isuues?

Douggie

NONE. I had glitching with a new Futaba digital servo. Now with the same servo, dead center and quiet.

[SweetAccord]

And I want to be clear that I am not referring to the module based systems. I am talking about the "hack" system where you open the transmitter and solder and remove parts, bypass parts and solder in the new RF deck. That you cannot do.

I'm not racing, so as long as it's FCC, CE & RoHS APPROVED that is all that matters to me.

[SweetAccord]

That is good news..what range and any glitchiing isuues?

Douggie

Range is excellent. Far as you can almost see in RC vehicle. In boat as long as the lake is here locally, and it's way over 300 ft end to end easily.

There is no local state, county or city law that governs a device is "illegal" if it's FCC, CE, and ROHS approved.

FCC: The Federal Communications Commission (FCC) is an independent United States government agency. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. The FCC's jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions.

These guidelines are strict and when a device is submitted for FCC ID the unit must be described where and how it will be utilized. So as far as we are concerned the Assan is not "illegal" by any general public usage.

What is being referred to as "illegal" is in racing and or private clubs which have their own rules and regulations, but the point is that for general public usage, these rules do not apply to the Assan hence all this "illegal" statements are NULL and VOID.

So if you are so sure they are "illegal" please call the FCC for us all and report this company, as none of us want to break any laws, keep us posted to what you find.

Thank you.

First, since you asked the AMA, this is from the 2009 membership manual:

Any user modification of a transmitter that might affect the transmitted signal is prohibited by law and safety concerns. This includes user replacement of frequency determining plug-in crystals and use of plug-in frequency modules from another manufacturer. Transmitter crystal replacement, with or without a change in frequency, requires transmitter emission realignment by the manufacturer. Use of a frequency determining module manufactured for use in another brand of transmitter can result in off frequency and spurious emissions that cause interference to other fliers.

Then from the FCC Regulations

47 CFR Ch. I (10–1–97 Edition)

Subpart C -

From Part 95.209 (d)

(d) You must not make, or have made, any internal modification to a type-accepted transmitter. (See R/C Rule 22.) Any internal modification to
a type-accepted transmitter cancels the type-acceptance, and use of such a transmitter voids your authority to operate the station.

§ 95.222 (R/C Rule 22) May I make any changes to my R/C station transmitter?

(a) You must not make or have anyone else make an internal modification
to your R/C transmitter.

(b) Internal modification does not include:
(1) Repair or servicing of an R/C station transmitter (see R/C Rule 21, § 95.221); or
(2) Changing plug-in modules which were type-accepted as part of your R/C
transmitter.
(c) You must not operate an R/C transmitter which has been modified by anyone in any way, including modification to operate on unauthorized frequencies
or with illegal power. (See R/C Rules 9 and 10, §§ 95.209 and 95.210.)

This applies to ALL RC transmitters.

There are a few other sections that also apply, but I think these make the point fairly clearly.

[SweetAccord]

Lets summarize: FCC governs here not AMA anyways.

As for the FCC: As already stated: The Federal Communications Commission (FCC) is an independent United States government agency. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. The FCC's jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions.

Also a device can't be FCC approved and sold to the US if it has not been FCC approved. By the way, Assans FCC License is: FCC ID: VJ9XRF01 Have you validated that it's not valid or counterfeit before making such a claim and ties it to Hobby Lobby's FCC counterfeiting?

Research before you make such a claim please: FCC official NO COUNTERFEIT ASSAN FCC ID:

If the AMA does not like something the FCC is doing they can duke it out.

Checkmate and nuff said, Im done.

[G Doggett]

Whoa - I'm almost sorry I mentioned my little experiment, but it is kinda fun watching from the sideline.
The rest of the world aren't really bothered about some weird laws within the US and will continue to buy these hack modules as fast as Assan can produce them to convert perfectly good radios to 2.4 Ghz.
I am very pleased with the way my conversion has worked out, and simply wanted to show anyone interested that it is possible to adopt this new technology without spending big bucks.
Graham.

[Bill-SOCAL]

Yep, some of this stuff is very odd and I am sorry it seems to have gotten out of hand. I tried to make a simple statement of fact but it sometimes seems that that is not enough. We have some odd laws here to be sure!!!

Take care.

And to SweetAccord - I sent you a PM but I'll just state here that you clearly are not reading the FCC regs, which yes, ONLY cover the US, but you still seem to not understand how those regs pertain to RC equipment. As to the AMA, that was a response to your post where you mentioned them. FCC laws very clearly state that within the United States that you cannot open up a transmitter and make any modifications, period. They also make it very clear that you can only use a module that was type certified WITH a particular transmitter. The module itself being certified independent of a transmitter does not apply.

But knock yourself out and do what you please, it is highly unlikely that the FCC will ever bother you.

BTW - your links do not work

One final comment - I wanted to make it clear that my original comments were about opening up a transmitter in the US and making modifications. That is clearly prohibited in the US. The use of modules gets a little fuzzy based on how you interpret what the FCC means by "transmitter". Some see that as the RF deck through the antenna. Others say that since what they sell does not include a power source or the encoder then they are still not OK. Like I said, the module thing is a little less clear than the physical modification thing.

The argument that because they sell it means it is OK does not apply. Lots of places sell transmitter crystals and it is absolutely not OK to swap them yourself and the FCC has made that clear before.

[SweetAccord]

Like I said Checkmate again! I'm finalizing my point with facts here. I spoke to the FCC today. So this is from them first hand! Jim Szelliga at 301 362-3000. Call and discuss if you want.

Q. Is there any law that states the following with the FCC Jim? "FCC laws very clearly state that within the United States that you cannot open up a transmitter and make any modifications, period."
A. No.

So not true! There is no such law.

Q. Is there anything illegal with how the Assan is being used installed of transmitting Jim?
A. "No, the Assan device fall under the 15C rules part.

Q. So what does that mean Jim?
A. There is no such law that states you can't open an already FCC approved radio and disable it and use the radio as host which is what the ASSAN is designed for as it's own stand alone transmitter. What is not FCC approved and illegal is to take an existing FCC radio and modify the EXISTING signal 75Mhz for example, or power output or the way it's broadcasting on that already FCC approved frequency which is 75Mhz."

So summary, there is no Law that says you can't open a FCC radio and disable it and use the rest of the radio as a host or shell and use the ASSAN that has been and is FCC approved as it's own stand alone transmitting device.

The ONLY issue is; the device is inside the radio and the rules say a device must show what the device is broadcasting at like a module would. So Assan just needs a sticker or something that shows the radio is operating as 2.4Ghz.

Q. Is this an issue Jim?
A. It's a minor issue but breaks no laws and that is the only real issue we see which is easily resolved.

I'm done. I hope all the people that are using the ASSAN are clear now that it's officially stated by the FCC you are not breaking any laws! Enjoy!

Well then I'll stand corrected. I will also contact them to ask how this squares with 47CFR Part 95.222.
