ok is their a update or should i up grade this scanner?
There is no upgrade available for your WS1040 so that it can receive ProVoice.
The only scanners currently that can utilize a paid ProVoice upgrade are Uniden models: BCD325P2, BCD996P2, BCD436HP, and BCD536HP. The current cost is $60.00 per scanner for the upgrade.
ProVoice is an option for EDACS trunking systems. Manufacturer support for EDACS is ending, and most agencies with EDACS systems are moving to a more current system type. In my area, Dallas/Fort Worth, DFW Airport is moving from their current EDACS/ProVoice system to a P25 (digital) Phase II system.
Looking at the database page for
Oklahoma County, I see notes that the county Sheriff's dispatch is moving to a P25 Phase II
system. If the city also moves to that system, your WS1040 would not work on a Phase II system. I know that in a few cases, the agencies using EDACS/ProVoice have a contract that mandates the manufacturer support their ProVoice systems past the termination date. Whether that is the case for the system in your city, I have no idea. That question would be better asked in the Oklahoma Regional Forum.
I would suggest that you request your thread be moved to the Oklahoma forum. Someone there might have information of any upgrades or changes planned for this system. To do that, do
not create a new thread. Instead, click on the red outlined triangle in the upper right corner of your original post, and request that a moderator move your thread to the state forum. Someone in the area would be more likely to see it there.
