RE: Radio problem with Spektrum
Seems like your area of the world is having some issues on 2.4 Ghz. I know here in the US there are a lot of users , and no one has had any issues that have caused problems you are seeing in the middle east (my reference from the US). There were few problems(2.4) at a rally in Dubai,UAE a week or so ago on 2.4 ? Might be some Local Government project(ECM) that hitting the frequency.
