The Whistler upgrade would enable you to use the WS1080 EZ Scan software so that you can get the latest Whistler firmware updates. I have seen many reports of the upgrade improving performance. However, the 1080 is not capable of NXDN. If Niles has gone to NXDN, you may be better off purchasing a new scanner capable of that. The Whistler TRX-1 does DMR and NXDN out of the box, but DMR has trunking problems. The Uniden BCD325P2 is capable of DMR and NXDN with paid upgrades, but has limited battery life. It does not have the nationwide database. If you want a scanner to receive P25 simulcast systems, the Uniden SDS100 is the only one that will reliably receive them. It is also capable of DMR and NXDN with paid upgrades. The model numbers I gave you are just for the handhelds. The TRX-2, BCD996P2, and SDS200 are the comparable mobile/desktop models. Meanwhile, we are dead in the water until the updated Niles information is posted on the database.
