I’m not a member so I don’t know if you are required to request access after joining the club and receiving the tones, but I would not expect that to be the issue.
It sounds like you’re on the right channel and you’ve double checked the tone. The only thing left that I know of is as you mentioned in your original post, getting closer. Once you are closer, when you hear traffic, try listening on the input frequency and scan for the input tone.
