Hi Folks Across the Pond - Are you having any wireless operating issues in UK with the 2.4GHz Navigator and Receiver set? We're having lots of problems here in the USA which uses the 2.4GHz Frequency Band heavily for Wi-Fi Routers, wireless home telephones, wireless home security systems, bluetooth devices such as wireless speakers, etc. Even microwave ovens and USB 3.0 computer hubs can cause interference with the 2.4GHz frequency band. I've sold two 2.4GHz Navigator/Receiver sets to customers in the last couple months and they both are experiencing wireless connectivity issues. I'm still using the older US 900MHz Navigator for my layouts and don't have any problems. The Piko 2.4GHz Navigator is also made by Massoth and some of those users here are also experiencing problems. These issues have been referred to Massoth for a solution for the USA user community. Maybe you folks in the UK don't have such wide-spread use of the 2.4GHz frequency with other devices?
