Bought the module for my Futaba 9 cap and very happy, just asked Santa for the Aurora 9 so will have the Futaba for FM and Aurora for 2.4. Will like to sell my futaba 9 cap and probalby the upgrade 2.4 hitec module will do the trick.

The coax cable did not bother me and see no problem. My only complain probably is that is to much work taking out the fm antena and placing the hitec module antena speclially if you take planes in fm and 2.4. Will modify a paper clip to just clip the antena to the radio holder instead of taking out the Fm antena.

All radios looks nicer with the antena on top instead than on the back, but if you want a module to exchange between fm and 2.4 think that having a module with a fixed antena is a better design.

Fore sure Hitec can´t make averybody happy, but the majority that is cost concient yes.

Thanks hitec giving us a nice and relliable product at a very good price.

Cheers,

Addressed to a group of nice people in this thead,

I am seiously considering stopping posting here because I am getting nowhere.

The more I read this thread the more It is trying to confuse me.

I still have not seen a picture of this module mounted on a transmitter and clearly showing the coax - wire. That is not seen in the links that have been provided.

Then I read things like " FM versus 2.4 ". I can interpret FM as referring to the lower bands (72 Mhz, 40 Mhz and so on ) I have to suppose that is the meaning of FM in these writings.

I would appreciate that someone comes out in the open and explain that 2.4 Ghz transmitter do not transmit FM modulation (either PTM or PCM)and show what they are transmitting.

SMP, SMP2, SMSS, FASST, FHSS, DSSS, all have nothing to do with modulation.
They are all methods of controlling the carrier frequencies that carry the modulation.

I still understand that in all these cases the modulation is still FSK (Frequency Shift Keying) which is a form of Frequency Modulation used in digital modulation (as compared to analog modulation used in speech and music).

I am wide open to learn differently if well explained.

I am still hoping that someone will post a picture of this famous coax-wire. (someone referred to it as this "infamous wire" ).

I still visualize the modulation envelope being the same in all these carrier handling methods.
They all still have to end up producing at the output of the receivers the type of signal that the servos are designed to work with.

Hey folks ___enjoy Christmas Day with your family and friends.

Zor,
Read Mike Maybeery post 3101 to you at the top of the page. He is a Hitec rep. Attached is the picture of the wire. It is cropped and has been posted before. Look under the crome handle for the line.

Zor

JN thank you.
I read all these postings many times including 3101.

So many thanks for finally seeing the coax-wire.
I do not see any zig-zag in it.
Which transmitter is this the rear of ?

The antenna is mounted where we see the long whip on lower frequency transmitters..
Does It mean that if this transmitter is switched to 72 Mhz (or lower) the case has to be opened to change the anenna ?

I do not see the antenna top but it looks like a commonly seen 2.4 Ghz antenna.

I am seriously thnking of getting an A9 and a receiver.
Can the A9 be switched to 72 Mhz with a module and ___
Does Hitec make a compatible 72 Mhz receiver ?

That could be a backup for my JRXP7202 .

Again many thanks and Merry Christmas.

Zor,
It is the A9. The picture that Jesper just posted is fantastic.
John

Zor

Yes ___again thanks to you and thanks to Jesper.

Observing the pictures with more details it appears that there is a whole assembly that goes from the bottom to the very top including the battery compartment at the bottom and including the antenna at the top that can be taken off and replaced by a similar unit that would include a new antenna for lower frequencies and a replacement battery pack and of course a new RF module.

If you can confirm that my deductions are correct, then I am fully happy of finally understanding how this all works.

Now I can have a Happy Christmas day .

U 2 folks.

I have seen the pic you attached to post 3112 many times a long time ago.
It does not in anyway give any idea how this is installed on a converted transmitter.

I just went back to post 3085 and in the first pic on the left there is a dark curved line which is no doubt the coax but one knows that after seeing a much better pic and can make that deduction. This pic in 3085 does not show the wire ends and where they go.
So it was not possible to know when I did not know what to look for. It surely was not evident at the time.

I have asked just above if there is a removable part of the transmitter case that goes from the very bottom to the very top and includes both the battery and the antenna. If so it would automatically change the antenna as the RF module is changed.

No answer received.

Sorry I just do not know how to write my questions any better than Ido.

I rarely get clear answers to my questions or my questons are disregarded so again please forget the question.
It is not possible for me to go and look at an A9. The only LHS around here does not carry Hitec so I tried to get info in this thread. .

Thanks for trying to help.

Merry Christmas.

This question
"I have asked just above if there is a removable part of the transmitter case that goes from the very bottom to the very top and includes both the battery and the antenna " was answered Post #3108.
The picture clearly shows thecomplete rear and user removable parts of an Aurora 9 and that the battery is housed in a separate pocket with relativebattery and door visible at the side.

That picture and others is from
Aurora A9 - Transmitter Mode & Stick Tension Change.
which and more is under
Aurora A9, Spectra Pro & Optima - FAQ & Undocumented Features .

also provding the answer to your question was:
"3. The dimensions of the battery compartment are 110 x 45.5 x 16 (L x W x H).
Refer pictures Aurora Battery Compartment posts #643 and #644.
Note page 13 of manual - Remove Lipol batteries and charge externally. refer:
Hitec Aurora, Eclipse, Flash, Optic, Prism series - Field and Fast Charging"

Zor

Alan,

I know you are really trying to help but it just does not work.
I still am not sure of what parts (area) of the back is removable.
I do not know yet if the antenna is mounted at the top on what is the same piece that is removable and would come off with the module.
I asked but still do not know if the A9 can use a 72 Mhz module and antenna As I wrote so it could be used as a backup for the JRXP7202 .

As I already said ___let us forget the subject. There is no point in carrying this on.

Just enjoy your last minute shopping. I presume that you are celebrating Christmas there in summer time. Here we are dreaming of a white Christmas (snow).

Thanks again from Zor.

Ya forgot to mention there was probably a good hockey game on too!

I do not watch commercial sports .

personally , i prefer the module and antenna the way it is
i have used a radio that the antenna is part of the module on the rear of the case
and find it much easier to damage it than the A9 antenna
when laying it down for starting the plane etc.

boothg-3

zor,you can remove the module and antenna from outside the radio
then install a 72 mhz module and screw in a normal metal telescopic 72 mgz antenna
the metal antenna is not supplied with the A9

Zor

Please read my red inserts below
If I am asking too many questions to find how this all work and fit together then just do not bother answering. .
Looking at a picture includes all the parts but it does not show how they are held together nor which parts are removable and how they are held together and how they connect electrically.
I cannot decide to spend another near $500.00 (approximate cost in Canada) for an A9 and receiver without knowing what I am buying. The local LHS does not carry them and I do not know anyone close by that owns one.

If the above is asking too much then do not bother replying.

For your info in case you ask ___by now I have spent hours going through all the details tn A.T. posting. It does not answer my questions above.
Having a picture of an item DOES NOT show how it comes apart so my questions were NOT answered as A..T. claimed they were.

Merry Christmas

Zor - RC transmitters with RF Modules have been around for many years, in the US. Before 2.4Ghz came on the scene, these modules just plugged into a socket in the back of the transmitter. The circuit board, in the module, contained the entire RF section of the radio, including the crystal. The Synthesized RF Modules, of which I sent you a picture, has Dials to allow you to change Channels.

There is usually 4 pins, inside the socket, on the back of the Tx. When you plug in the RF Module, the pins enter a connector in the back of the RF Module.

The back of the Transmitter has no Door or Cover. It just has a rectangular hole just large enough to Snap in the RF Module.

Spektrum came out with the first 2.4Ghz RF Module and it plugs into the same socket the the 72Mhz RF Modules plugged into. Since the entire RF section is included in the RF Module, the Transmitter does not care which band the RF Module is on.

Some 2.4Ghz RF Modules have antennas built in to the RF Module and some have a Coaxial Cable that runs from the RF Module to an External Antenna that sits on top of the hole where the Original Metal Antenna was screwed in.

Some RF Modules have a Threaded Stud, protruding from the back of the RF Module, where you can Screw in the 2.4 Antenna or connect a Coaxial Cable to an External Antenna.

It is as simple as that. Plug and Play the Frequency of your choice.

One difference between the XP9303, with the Spektrum RF Module, and the X9303 2.4, is that the XP9303 does not have Model Match and the XP9303 has greater Latency than the X9303 (it takes slightly longer for the servos to react after the stick is moved). This is especially important for competition Heli pilots who absolutely need that extra speed.

Some manufacturers of the newer 2.4Ghz radios have models that do not have sockets for RF Modules. The RF Section is built in to the Transmitter. The DX7 is an example. Other radio manufacturers, like Hitec, produce a Tx model that Does support RF Modules and Backward Compatibility with 72Mhz RF Modules.

After Spektrum introduced 2.4Ghz RC radios, they started offering 2.4Ghz RF Modules to convert older RC Transmitters from 72Mhz, etc., frequencies to 2.4Ghz. Futaba and many others eventually followed.

Well probably best that you download the A9 manual from www.hitecrcd.com and then buy and A9 so you can see how good it really is.

Zor

Jim,

Thanks for the link.
I will download the manual if I can right after I respond to BuschBarber.

Hopefully it will have some answers for me.
I have been looking for the manual and had not yet found if it is even available on the internet.

Since you know how good the A9 is, I guess you must have one. Perhaps you could have answered some of my questions. .


Wishing you and yours "All the best for the Holiday Season and the New Year 2011.

Zor

JIMF14D

Well I think the questions have pretty much been answered. AT has forgotten more than I will ever know about Hitec products.

Iwould say you should look at the manual, buy one or go look it in a hobby shop. The whole thing is so simple, you will pick up on it in 5 min.

You can find the manual under downloads and Aurora I think it is.

Have fun

Why does this bring to mind the revenge of DBCISCO if you all recall the past......

Sold my Futaba 12Z and my 12FGA, purchased a A9 instead, does that tell you something ? Programming with an ease was what i am looking for and that came with the Aurora system. I like this Radio a whole lot better.

If it's anything like where I live, I would LOVE to have a hobby shop that carried Hitec stuff in stock. They'll order it special, but they only keep a very small number of radios available, like one JR, one Spektrum, and one or two Futaba. There isn't any "go to the local shop" and look at one.

I've tried to talk the local guy into stocking an Aurora 9, but no luck yet.
