Hi all,
I am planning to modify an existing handsfree set for use with my XDA and during planning I found:

On this page you will see the following line:
Anschlussmöglichkeit für externe Antenne

For those that can't understand German: Can support external antenna
How do they do this? I have not found any reference of a connector for an external antenna.

It probably uses a passive coupler. If you place a properly-designed coil very close to the phone antenna it will couple RF effectively.
Your right!
Got the car kit yesterday. Opened the cradle and found a large piece of PCB that is positioned close to the antenna of the XDA. This PCB is connected to the lead that comes from the external antenna.
Francois
Yeah, a passive coupler. Makes sense. It should give you a 3-5dB boost, good enough to clean up conversations in fringe areas.

Sorry,
whats PCB???
Can U make a Photo?
Stevie
PCB = Printed Circuit Board.
A foto would be overkill, just imagine a piece of epoxy 5*5 centimeters, covered with copper.
Francois
Hello FVH,
would be nice to hear your experiences with the car-kit.
Does radio mute work ?
Does the sound work through the radio speakers ?
What is in the box of the car-kit ?
Is it worth the money ?
Thanks :lol:
FVH,
Re the PCB description, is it just as you say "a flat piece of copper" without a pcb design on it, if it does what does it look like... are there any other components on it?
e.g. can we make one up easily!
using sticky back plastic or veroboard - e.g. Blue Peter with a bit of Maplin thrown in to achieve a better xda signal...
So if this thing really is just a flat plate, and has no intrinsic components, pcb tracks or special properties...does it that mean we could just rig up a sheet of tinfoil or other conductive item nearby...
I guess we need a Radio Ham with an xda to tell us we're onto a lost cause - Hopefully owning an xda is not like the early days of broadband, where you have to base your homebuying/renting on where you can get a service!
Or someone who's tried out the inductive antenna as mentioned on the other thread http://www.xda-developers.com/forum...=0&postdays=0&postorder=asc&highlight=antenna
http://www.expansys.us/product.asp?code=AXF-15S
You can make a perfectly tuned antenna/pickup out of just copper etching on a piece of PCB. Unfortunately, it is infinitely easier to create a distuned antenna from the same components.
After a lot of research it seems the "as seen on TV" signal booster widgets (small PCBs) as suspected dont work.

This is a brilliant site where I found all the info:
http://www.criterioncellular.com/html/reception.html
Whats needed is either:
1) someone making a replacement antenna - as from the internal images shown on this website, it seems fairly easy to remove when dismantling the xda. Why not have a replacement one with an external FME antenna connector. This could then be attached to a small car type antenna.
http://www.tdc.co.uk/antennas/antenna_gsm.htm
apologies if my theories are a little optimistic on this... its just an idea.
2) Purchase of an external signal booster, which can be attached to a small antenna. Then directly plugged into a modified antenna (as 1 above)
3) A seperate re-radiator to boost the outdoor GSM signal inside the home, although this seems expensive! ($279)http://www.criterioncellular.com/html/cellular-amplifier-bda.html
4) as carlos suggested an inductive repeater, you can buy these for GPS systems, why not for GSM signals?http://www.expansys.com/product.asp?code=GPSW-RRAD-45
FVH - Have you noticed any difference with signal using the inductive coupler?

Hi, can you help - 02 can't! I want to connect to the black plug, labled as number 13 - in the car kit user manual. its a short lead from the main thicker wire from the "box" to the xda holder.
What type of plug is it? anybody know where i can get the other side to connect to my other bits of kit.
thanks in anticipation. Simon :shock:
I dont know exactly the connecter but if you have a Maplin store local to you, it might be worth a visit, they have an incredible array of connecters, converters, adaptors etc.
Hello !
I assume that you are talking about the flat connector, if this is the case it's mensioned for data in/out like GPS etc,
For what purpose do you need this connector ?
The connector i am looking at it a flying lead off the main loom from the car kit electronic box to the xda holder. i am looking at using it for gps. i know which wires to use and have the system working fine. its just not a very elegant solution. i would like to make up a short lead using this connector and my gps to offer the system to my parants cars and my sister. the way i have done it would invalidate the warrenty on the car kit.
thanks. simon.
Hello Again !
smart (car manufacture) have a GPS which fits directly to the connector of the harness.
Part nr. is 0015829V001000000 and can be delivered by any smart-Center in Europe. :lol:
Ok this may sound silly and i am new but can someone shed some light as to why there are two external antenna connectors on the Tytn 2. Theres the plastic flap on the back cover for the GPS antenna but if you take off the battery cover you can see that there are two ports next to each other. Are they both for GPS (two different types of connectors since they are different sizes) or is one for gps(hence the plastic flap revealing only one port) and the other for phone signal???
I've had a quick look around for an answer but haven't found much.....
Any help would be appreciated!!

According to page 92 of the service manual (available through links on the Kaiser wiki page) the other connector (WCON1) is a RF port and since it's not covered in the user manual and isn't accessible unless the battery cover is removed, it'll be for factory testing purposes only - ie don't mess with it! The other one is covered in both manuals and is, as you note, for a specific compatible HTC external GPS antenna.
Hey guys,
I think some of us have a problem with our headphone sockets where over time, slight bumps to the connection causes the audio to slightly cut out which can be annoying if you're listening to music with your phone in your pocket through headphones/earphones.
Now I've found a guide to disassemble the phone which i'll leave at the bottom as not to ruin the continuity, but I'm struggling to find a suitable replacement part for the output socket on the phone. You have to remember that the socket also needs metal contacts inside it for the microphone input. I plan to shoot motorola's technical team an email about it but I'm wondering if there are any other people keen on fixing the problem or if they themselves have tried addressing it.
Cheers,
Ed

Something which is close but not quite what i'm looking for:
http://www.jaycar.com.au/productView.asp?ID=PS0133
seems interesting.
I've had to send my phone in twice because of this.
Might have this problem fixed now though as i've gotten angled headphones that are really close to the socket. This way there won't be as much pressure on the socket when i've got the phone in my pocket whilst cycling.
hmm... been a long time since I´ve tinkered with any jack-sockets (last time on one of my bass guitars), but shouldn´t you just be able to -probably more of a temporary fix- bend the contact-latches inside the socket a bit so they press "harder" against the headphone jack when it is plugged in?
that way, they should allow for more movement of the jack (which is the problem you are describing) without losing contact.
the only problem is, repeated usage of the socket will eventually wear the contact latches out again over time...
Through the course of my research I've actually found a really simple and easy quick fix which works really well.
Spray a bit of WD40 into the socket and abrakadabra! it works!

Really? Why does this work? Does the WD40 conduct the signal? How often do you need to do this?

Bad idea. Don't use WD40. It will eat away at the plastic and circuit board. It also will attract dust and dirt. Electrical contact cleaner is a better idea. It's safe for circuit boards and plastics.

Where do we get this stuff? My current milestone is fine...but for how long? My first unit's headphone jack was very bad after a few months.

In China, that part (original) is about 2RMB - say $0.30 US - but shipping it will cost far more than that...
The Motorola P/N is 0976622A01, and googling it seems to produce a few hits:
You will need to find the links yourself, since the board prohibited me from postiing them...

the board is prohibiting links??? or only certain links?
however, i would appreciate some more hints on that disassembly-guide you were pointing at, since i cannot find that, either.

Have you tried the electrical contact cleaner post yet? Someone says WD-40 works (Which is a terrible idea, hence trying electrical contact cleaner). They aren't cheap and it's worth a shot before taking your phone apart!
Thanks! This is great!

this may work, but I have found on the portable devices it is normally more the circuit board it is connected to. The solder joint fails and really needs to be re-soldered. The connection is only supported by the solder, not a good thing, but all the electronics manufacturers only care if they last past the initial warranty. Often all it needs is a hit with a low power solder gun to re-flow the joint, other times you need to clean off the old solder, and put on some new. the joint will often look fine to the naked eye, but if you look with magnification you will see the joint has cracks. A friend of mine is an electronics repair geek, and he can see it just by glancing. I need some magnification, funny thing is he wears glasses that are almost an inch thick, so it is more experience at looking at them.
Thanks for the links. My audio jack has been bad for some time and it is only a matter of time until the frustration will drive me to take the phone apart. It is better now I have some instructions for when that time comes
I tried contact cleaner which unfortunatly didn't have any effect. It 'feels' like a bad solder joint but obviously I can't tell for sure until it is apart.
Hi all,
My HD2 running HyperDroid v12 from Pongster is a dream phone. Everything is working excellent except recently I got the digitizer changed from a local shop here in LA and in the process of fixing the digitizer the idiot seems to have ruined my GPS related hardware (which obviously he is not owning up to). I tried all sorts of software remedies (including changing ROMS) but nothing seems to get a GPS lock.
My questions is -
Is there any way to buy and replace the GPS receiver in the phone?
Thanks
The guy might have accidentally removed the connection from the circuit board, I remember seeing threads from before of other's doing the same thing when fixing the digitizer.

They tell you what you need, and instead of the "flat plastic stick", a guitar pick should be fine.
- No need to remove speaker from housing.
- Ignore everything from 1:47, and look at 3:22 from the disassembly video, instead of removing the gps coaxial cable, check if it's actually connected properly, if not, just push it in.
_______________________________________________________________
I'll try and find those threads I remember reading, in which the OP and other members had the same problem after replacement of digitizer.

Hi Moon,
I followed the steps in the videos you provided and opened my HD2. The GPS coaxial cable seems to be fit in snug, which I guess is indicative that the GPS antenna itself may have gone bad somehow. Possible?
I did a little searching and found this link where I can buy an antenna from -
http://www.gsm4world.us/oem-htc-hd2-t8585-gps-antenna-board-flex-ribbon-cable-d-03752_579.html
That said, I am not too comfortable trying to replace it by myself. Any chance anybody knows a person/shop in the LA area who may have expertise in such jobs? The one I found in Glendale (CellularDR) is the reason this has happened so I'm not too keen on re-visiting them.
Thanks again for all the help!
Can't you get a separate external GPS receiver and bluetooth it?
It kinda beats the purpose of havnig a all in one device, plus you need to always watch 2 batteries and not just one . But, I must say it is the safe option and worth considering.

New back housing w/antennas
I had to replace the back housing on my phone as it broke (it looked like the plastic had deteriorated), and the new one comes with all 3 antenna attached, and a new battery cover for less than US 20.00. I have better reception now on all 3 radios, and the phone looks new again. If your have to take it apart anyway, why not replace the whole back? I got it from these people, eBay item 350487086071, but there are tons out there, and it was dead simple. Unscrewed the four screws, used the plastic piece to pop the snaps, and that was it.
YMMV, but for only 20, you can rule out the antennas if nothing else.

Hi mate, thank you so much for your reply, great tip, and good to know that is good quality product, and because I have a spare battery cover I bought only the chassis.. great price I will start from there.. thanks once again.
Sent from my HD2 using XDA App
Hi been having trouble with WiFi being very spotty, and thought it was because of the little Pig Tail antenna used, however after opening up the unit to solder in a proper antenna I found out that the reason it was so spotty is because the solder pad where the original antenna was soldered to was only hanging on because of some glue that had been applied.
I only realised this once the glue and solder had been removed.. exposing the now missing solder pad..
Looks like whoever did the QC spotted the loose solder joint so just put a blob of glue on there lol.
Does anyone know of an alternate location where i can solder in the new antenna? having just has laser surgery on my eyes I really dont want to spend a few hours tracing lines etc.
Its a Car Joying unit, Quad core 3188, 7" Tablet type with capacitive keys.
