![]() (thought there was a way without the full db) Then after it completes, go in the list you created and see if the things you cant listen to are listed. This will use info from any saved favorites list you have and plus the full database. It will then ask you to pick a fav list to add to, or create a new one. Instead of doing lat long, hit the zip code button and enter your zip code. ![]() What you should try is go into Sentinel, read your scanner, and then hit edit, and look for "add channels on range". I chopped the end, fed it power, and believe it was only one wire needed to pass the data.īut, all the gps is going to do is tell the scanner your location, and if its the same location as the one you already entered, its going to do the same thing most likely. I am pretty sure that is the same gps I bought for my 436. It sounds like it may not work either or even be worth trying, as for I do not use my Uniden BCD536HP Scanner for Travel use purposes. Therefore, I was going to go at this to try to accomplish Location Control Scanning at my House with a GPS Receiver to see if that would work & be the trick to accomplish Location Control Scanning to help filter out all of the other far away & annoying Dispatch Calls that I have to hear & listen to on the Statewide Digital Trunked Radio System here in New Mexico. Even with my low set Range on my BCD536HP, my exact GPS Coordinates for my Home programmed into my Scanner, as well as the exact GPS Location Coordinates for the Statewide Digital Trunked Radio System in my State which were downloaded directly through Sentinel for the Trunked System. The Location Control on my BCD536HP is not & was not working correctly to filter out & let me just hear my local Fire Station down the Road from me on the new Statewide Digital Trunked Radio System for my State. If you get some other GPS device to work, please add a short howto to this page.Click to expand.Yes, I definitely knew that & have tried it without success. Depending on your special USB GPS dongle, you have to follow the one or the other instruction. A GPSDO (GPS Disciplined Oscillator) is typically used which locks a temperature-compensated oscillator to the GPS time and provides a stable, reliable reference.īelow you find examples for some devices users have successfully got to run with LEDE. Proper GPS synchronization uses a PPS output (or similar) from the device, fed directly into an interrupt-generating line, for example a GPIO or parallel port. Any such-configured NTP server certainly can serve as a backup for local timekeeping when Internet connectivity is not available, but should never be advertised on the Internet as a Stratum 1 clock. Your notion of time will likely be delayed by tens of milliseconds if not hundreds of milliseconds. Please realize that connecting a consumer-grade (designed for location, not for time keeping) GPS unit over USB serial does not have the accuracy of “proper” GPS synchronization due to significant and inconsistent delays in the serial line itself, as well as in the USB system. Most GPS-sync is done through GPIO interrupts off the PPS output directly. This approach may be off by hundreds of milliseconds. There is significant delay in the serial-to-usb and usb-to-data connection.
