SDS100/SDS200: SDS 100 modification for internal GPS

[jlynch4614]

Does anyone know where you can get a new SDS100 modified with and internal GPS.

Apparently, the only person who has successfully produced that modification has chosen to move on.

Jon Weinke produced an internal GPS for the SDS100 and a rechargeable external GPS for the 436. Fortunately, I have both and they work great, although I seldom use the rechargeable one now. While he was around, he gave top-notch advice online, made 3D-printed latches for the SDS100, cleaned up Uniden's warranty repair that they could never get right, sold certain antenna connectors and, yes, modified SDS100s with an internal GPS. The pandemic complicated his supply chain from Asia, some personal problems creeped in and it went downhill from there.

Now we're waiting for hell to freeze over or for Uniden to try to duplicate Jon's work. I can guess which will be first.

Not quite. His health forced him to move on. I'm sure he'd rather still be doing them.

Sorry to hear did not know Jon was having Health Issues.
Thanks for the update.

I don't ever recall Jon mentioning health issues of his own. He did comment several times about his girlfriend falling ill with stroke-like symptoms and requiring most of his time for care that took priority over his scanner interests. After he posted that she was doing better, he was running into problems with some bad components and supply chain issues for the GPS mods and having difficulty continuing with the mod service.

After that, Jon did post that he chose to move on to other interests that were demanding most of his time and attention with publishing deadlines etc. He is now writing sci-fi books under the pen name of "Jackson Wilcox"

He still sells some 3d printed items on ebay, but hasn't been seen on RR for over 2 years....

I used the ATGM336H. Mini GPS Module for Arduino (ATGM336H + Antenna) — Maker Portal
I then routed its TTL output to a micro RS232 converter https://www.amazon.com/HiLetgo-Level-Converter-Board-Rs232/dp/B00LUDCAXQ

I connected the output of the RS232 converter to the pins of the GPS port where they meet the board internally and fed it all from a 5V voltage source I probed around to find internally. It all fits in the area where the belt clip button attaches. There is no need to cut or damage or do anything to modify the radio that can't be undone later and it works amazingly well.

I would do these for others but I don't have the time and I don't want to deal with people inevitably saying something was broken or damaged. But, with a bit of experience in soldering and basic electronics knowledge you can do it yourself.

I have read your info and am going to try this externally first. Can you update me with a schematic or drawing of pin to pin connections? I have purchased the above mentioned board and have a break out terminal on my gps usb connection to supply signal.
Thanks,
G.

Do you have pics of install?

edit: also how did u install antenna? Or did u not use it?
