Module & Receiver issues

[chandler100]

I have an issues with my car as it seems lose signal at the far end of the hall.

I'd like to try to eliminate the cause. I have a KO Propo EX-1UR 2.4ghz transmitter fitted with a Spektrum Module and Micro Receiver.

Can anyone lend me a replacement Module/Receiver to test and elimate the problem?

Or if you have any other ideas as to what the problem may be please feel free to comment.

Thanks
