    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    In other news, my girlfriend is doing much better, I'm starting to make a dent in my backlog, and I'm current on shipping orders, except for the items referenced in my previous post. And there is one other notable thing going on in my life that isn't scanner or radio related, so I created a...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    I have some extra flash chips to retrofit GPS modules that have lost their settings because they don't have one. I have 2 or 3 SDS200 externals in stock, but I can't get more modules. PM or email me (jonathan@unidenscanners.com) with the email address you used for the PayPal order, and I will...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    Update: I got the flash chips from Reyax, and I was able to install them in a few modules for testing and let them sit for several days. The good news is that installing the chip seems to be the correct fix for the settings loss problem, so I installed chips on all of the modules i have on hand...

    MMDVM for bi-directional repeater

    Not my experience. I had a friend with a 578 in his truck park on a hill west of Martinsburg WV in SFR mode, and made contact from Stephens City VA to Hagerstown MD through it. It wasn't the best reception, but we made contact.

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    Thank you to everyone sending support and well wishes, here, via PM, and email. There are too many to thank individually, but I really appreciate you all. Some miscellaneous updates: My girlfriend is doing somewhat better. The initial symptoms were very similar to a stroke, but bilateral...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    I apologize for my absence lately, my girlfriend had something sort of like a stroke and spent nearly a week in the hospital. She's doing a lot better, but is still having issues walking and doing various other things without help, so I haven't even looked at my workbench in almost 2 weeks. I'll...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    That's up to you. It's going to be a few weeks after I get the chips before I will be able to work through my backlog, so if you want to hold on to your scanner until I've made a dent in it, that is totally understandable.

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    Yes. I have a tracking number from Reyax for the shipment of flash chips, but it doesn't yet show an estimated delivery date. I will post more when I know more. I apologize for the inconvenience, I know this sucks for everyone affected.

    Firmware Bug Affecting All Uniden GPS-Capable Scanner Models

    The uncased modules I use cost about $15 each retail.

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    I can report some progress. Reyax has agreed to send me a batch of the flash chips whose absence are causing the problem. Instead of mailing the modules to Taiwan and getting them mailed back, I can install the chips on modules as I get customer warranty returns, and do a quicker turnaround...

    Firmware Bug Affecting All Uniden GPS-Capable Scanner Models

    As far as I can tell, it is the exact same hardware as the Uniden puck, the only difference being the brand sticker. It's GPS only and uses the GP talker ID, so it doesn't trigger the bug.

    Firmware Bug Affecting All Uniden GPS-Capable Scanner Models

    All versions of firmware for the SDS, x36, HomePatrol and x96 models are affected. My guess is the NMEA sentence parsing firmware code was written incorrectly for the x96 family, and then copied over to the other model families when they were developed and introduced. But Uniden-branded pucks...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    FYI here's how to tell if your unit is affected by the issue, if you feel handy with a screwdriver: You'll have to open up the scanner or external GPS, and look at the back of the GPS module. If the chip indicated by the red arrow labeled FLASH is present, then you do NOT have the problem, and...

    Uniden Scanner Mods & Accessories - SDS100 Internal GPS Mod

    I'm having issues with my GPS supplier right now. I've been in communication with them, and discovered that the entirety of my most recent order of modules is missing the flash chip needed to permanently store configuration changes. Without the chip, the module will revert back to the factory...

    Scanning vrs Searching

    Yeah no. Tweak the center tuning frequency (middle of the waterfall display) up a few KHz. If the signal shifts to the left like everything else, it's not an image. If it shifts to the right, as if it's moving to a new frequency, it's an image. It takes maybe 2 seconds per frequency to test.

    Not true. If you manually change the tuned frequency, the signal will move in the opposite direction of an actual signal if it's an image.

    Help me help you

    Like I said, I can't replicate the error on my SDS100 or SDS200. Are you pressing Func and Dept simultaneously, or Func, then Dept?

    My test is scheduled!

    He logged in April 18, so either he's alive, or one of his heirs has access to his RR account. My money's on a test failure due to the VEs not accepting test answers based on alternative physics.

    BCD325P2/BCD996P2: BDC996p2 reception problems

    Repeating it again with emphasis. NONE of the simulcast workarounds are helpful when you are not in a fixed location. Attenuation (deliberately using crappy antennas, no antenna, putting the antenna in a paint can, and all other means of reducing the signal) will not help when your received...
