Can get it made custom usually.. There's plenty of prototyping houses around. Gotta become a ham operator (if you're not one already), all sorts of fun resources out there.

I'm probably not the kinda person to do either, but there are more adventurous people than I am out there.

Yeah, there is, but that's really not cost effective unless you intend to go into production in quantity, and well, I'm not.

That's what prototyping places are for.. Small batches. Production quantity is another breed of cat.. There are many places that'll do 10 unit runs.

But I am interested if the plug is custom or if it's an available part.. If it's an available part, I'd just etch myself a board.

I'd be a little more daring to hack up my antenna headphones if I knew I could by another pair, but I think we'll never see them as an accessory since people have largely expressed hatred of them. This merger talk has probably ruined the possibility of getting an external antenna either.

from what I've measured, the circuit looks nothing more than a couple of 2k resistors (probably one to signal external antenna and another to signal to use the internal battery)

Sure they will, but check that cost effective part again.

And besides that, you can etch your own boards but are scared of cutting into a few wires? Chicken!

You'd be about right there. I counted two resistors.

I'm not afraid of cutting a few wires.. I just don't like the fact that I'd be ruining something I can't get another of easily. I'm the kind of person that'd sooner get someone to mold me a connector.

I can see that.

Here's an added bonus for me though. I can use my antenna headphones from my Roady2 Personal kit as well. Fits great. They are much more comfy and sound better than the Stiletto one. And they have built in volume control to boot.

I thought about just cutting the earbuds off the headphones and making a velcro shoulder antenna. However, I think the Cirocomm gear that is in the headphones is junk compared to the Sirenza dot micro.

DaJoker,
I'm curious if the painphones connector uses the same power as the docks put out to power the micro-dot. Have you done any comparisons on reception? IE micro-dot antenna directly connected to "DaJoker-Port" Vs car dock with same micro dot driving on a familiar route with trees and other cut out spots ?
Or maybe compare out put voltage on your adapter vs out put of car/home dock.

Thanks bunches.
Xan

Nope, didn't do any voltage comparisons. Don't have a car dock. But I did have 3 bars on by home dock, connected to my port, and 3 bars.

thx.
Another bummer for the S100 is having only 3 bars to tell how signal is.

I'll have to see for myself when i find the damn soldering iron.

It consists of two halves, and a push button (with spring) that controls the clips that click the connector into the Stiletto. This one remains pretty much undamaged, but it originally is epoxied together as halves, and must later be epoxied back together. Then, there is a rubber sheath that surround the circuit board and the wiring. This sheath must be cut apart to get to the circuit, and in the process you pretty much destroy it, and if you are careful enough, you don't destroy the wire. It is VERY difficult to not separate the wire from the circuit though. The red and black audio wires are VERY small diameter wire (total of 5 twisted strands from my count), so it is very easy to break them or cut into them when cutting away the sheath. Basically, unless you have plans of following through all the way, I wouldn't go cutting into this thing.
The Outer Sheath comes apart fairly easily. I used a small pen knife and put it in the small space and turned it slightly which released it. I repeated this with the other side and was able to pull up the button.
Since it no longer stays together, I assume a drop or two of super glue would do the trick.

Now my question, What did you use to cut apart the rubber sheath surrounding the circuit board. I want to be very careful at the same time, want to insure I have something to put back. I can see from the pictures that you no longer have the cable strain relief and the wires for the antenna connection and earphone connection are just coming directly out of the outer sheath. Did you use shrink wrap or electrical tape or anything lese to replace the destroyed inner sheath?

From the photos It looks like there are small square pads where you solder these connection too. It's hard to see where to connect the wires from the RF connector Tip and ground.

In your post you say:

"there are four connections going on here. You have Left, Right, Coax Tip, Coax Ground. There also are what looks like two resistors on the board, but it's very difficult to follow what they tie into"

Can you be a little more specific or will it be apparant once I open it up where these connections go?

If I can get the RF connectors I'm going to try it next weekend. I have a nice headphone extension that I will cut up for the headphone connector, but I want to get a nice cable for the antenna connector. It needs to have some sort of strain relief along with some room to grab the cable to pull apart the connectors. Normally the RF connectors can be on tight and take a little pulling to get them off so I don't want to have this too fragile. Also as I've soldered plenty of PL259 connectors for my Ham gear, I know it is important to make the connectors well, making sure there are no shorts between the tip and any of the ground wires.

DaJoker, Thanks for your help on this. It looks like a fun project!

Mike

Hey M_R, I noticed that when I did the earbud project on my painphones that the antenna wire that goes to the trapezoid shaped antenna is the same type of wire on the microdot or any standard antenna. What I was wondering is that is you used the type of connectors that are pictured earlier in this post by me and just crimp a FSMB onto the wire and plug a standard antenna into that. Do you think that it would still power the antenna? I would think so because if it is recognizing the headphones are connected to the stiletto and providing power to the antenna, then you would think that it would still power to the fsmb connector to whichever antenna you elect to connect.

me_rubin: do your best to take high quality pics when you get it open, so we can figure out the resistors. I've also been trying to figure out the cheapest source of those universal dock connectors .... sportster 4 home dock?
