Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

[LESTERTIRADO]

Please let us know how this impacts the battery life of the SDS100.

Hello. I'm trying to get my SDS100 mod. But who do I contact? Is John still around?

Lester k2ltm@aol.com. please help.

Jon is still around but, apparently, he's on hiatus because of some personal issues. In addition, the chip shortage has also interrupted his service. He still chimes in here once in a while.

anyone know a part number to the internal gps module Jon was using?

He built them himself, I think.

It was a module from Reyax the RY825 that are no longer available. They have the $30 RY826 but don't know it that will fit. It seems to be useable with its default settings. RY836AI | REYAX TECHNOLOGY 爱联智科技

Surely Uniden is planning a new model of this scanner with built-in GPS. Should just be a matter of time. I’m waiting for that.

Bluetooth would be nice, too.

Just to listen through a BT headset or what?

 

[KK4JUG]

GPS?? Bluetooth? C'mon, guys. Let's get serious. Where's that waffle maker Paul promised?

They could have easily implemented this to start with.

IDK, have you seen how inefficient their “current” GPS solution is for this radio? Just awful.

You're right. On the other hand, Jon's was (or is) an excellent piece of electronics. I did no special testing but anecdotally, it appeared to only use about 15-20 minutes of battery power over a full day's use. If Uniden would (or could) use Jon's design, they might have something. I don't know if he got a patent for it. Besides electronics, Jon had also "interests" other than electronics which may be consuming his time now.

There's no special with Jon's use of the GPS module. You take a readymade GPS module and connect its TX data to the scanners USB ports RX, that's it. The trick is to find one that doesn't RF interfere with a scanners reception. That's why Uniden didn't want to have GPS or blutooth inside the scanner. Although several 2-way radio models have it but it might need a lot of work trying to shield them away from the receive electronics.

A reminder that this thread is for feedback on the GPS module that Jon sells/used to sell. If you have concerns about Uniden's past and future product designs, discussing them in one of the Uniden forums, probably the Uniden Tavern, would be more appropriate.

I use 2 Jon Made External and 2 Uniden Made all 4 work the same.
The 2 Jon Made me are the same parts he used when he mounted them inside the scanners.

Wonder if this could be wired to use power from and feed data into the USB ports on side of SDS100 ?
Would not be as slick as the internal unit done by the master here but might be a good "2nd choice" of if combined in a small package that clipped to the scanner ?
Anyone have pinouts for USB1 and USB2 in the side of the scanner ?

It's USB. It's a standard. USB hardware - Wikipedia

I can't find anybody local that can solder such microscopic leads (On the USB)

Those leads goes on the circuit board to other components that are easier to solder to. Sometimes there's a capacitor for each pin and sometimes protection diodes and at other times the actual IC that handle the USB signaling have bigger copper surfaces to use. Take out your multimeter and check for a 0 ohm connection from the pin.

I was thinking the same thing. If I can get a small enough module I can install it myself.

I had that issue in an AnyTone unit. Some aluminum tape solved it real quick. I covered the flash memory chip with electrical tape, then aluminum tape atop that, the radio works fantastic even with both BT and GPS always on.
