![]() Whistler WS1080 CPU Firmware versions of 3.9 and higher are reported to not work for DMR receive in the other 3 scanners at this time.įor those concerned about possibly "bricking" their scanner with this procedure, you really have nothing to worry about. The winning combination at this point for the PRO-668 appears to be Whistler WS1080 CPU Firmware version 3.8 along with Whistler WS1080 DSP Firmware version 3.0. I have personally updated my PRO-668 scanner to have DMR receive capability and it is working fine on both conventional DMR and DMR/MotoTRBO trunking. Apparently the hardware of all 4 of these scanners is VERY similar (although not identical) and that allows this "sharing" of some versions of the CPU and DSP firmware to work. The update procedure involves loading the CPU and DSP firmware versions that were publicly released for the Whistler WS1080 scanner into the other scanner models and that then allows DMR receive capability. ![]() If you are interested in updating any of these scanners for DMR receive (or adding Phase II to a PRO-18) you should give both of the following RR threads a very thorough read: In the case of the PRO-18 it apparently also adds P25 Phase II capability which it never had. It makes this scanner and other scanners such as Uniden really perform.I don't know if anyone here at SNE has been following the pertinent threads over at Radio Reference but it is now possible to add DMR receive capability to the Radio Shack PRO-18 and PRO-668 and the GRE PSR-800. Right now it is one of the best scanners available. The mini ssd card is easy to program and the data base is f ree for life. It makes it a lot quicker to download to your computer the data base and then adjust the parameters that you want your scanner to follow. I highly recommend using a card writer / reader to program this scanner. Getting used to the programming on the RS pro 668 is easy once you start getting into it. They are one of the best scanners out right now, I prefer this scanner to the Uniden Home Patrol II and the other Unidens as the Radio Shack pro 668 has better audio and a better receiver than any of the higher priced top end Uniden scanners. Of all the scanners I have owned, I now own three of the Pro 668's. I have owned almost all the top end scanners.Radio Shack, Uniden, GRE and even some other brands some have not heard of. ![]() Verified purchase: Yes | Condition: Pre-owned I think you will be pleasantly surprised just how much easier listening to the public service bands (and a LOT of other frequencies) has gotten. If you have bought scanners in times past, and then gave up when you could not get the information you wanted in order to listen to your local police or fire departments, give this versatile unit a try. You will have questions as to how to find the specific user groups that interest you (taxis, specific police talk groups, your local dog catcher) but at least you are hearing most of what you bought your scanner for. Sure, there is still a learning curve involved. Put the batteries in it, answer a few questions at start-up, and much of the programming has already been done for you thanks to the supplied data card. The Pro-668 had made this process a whole lot simpler. You needed scan lists, programming software and cables, and more than a little time to learn how to make your scanner listen for what you bought it for in the first place. In the not to distant past, police scanners, especially trunking scanners, were more than a bit difficult to program and be useful. Good Scanner for Those Unfamiliar with scanners
