Hi,
Can anyone advise me please?

I initially had very good results running just 5 watts to an indoor whip, mainly on 80, 40 and 10 metres. However since yesterday I am getting zero spots. I have tried everything I can logically think of, reloading, ensuring RF is going out, audio ports are correctly set etc but I suspect that I am not sending the appropriate data. How can this be checked please? I don't have a scope but listening on a remote receiver I can only hear what appears to be a continuous tone; should I be able to hear a content of data? Any advise will be extremely welcome please as total frustration has now set in!
