Default Jpole tuning

I did some tuning with the J-pole. Sliding the feed point and placing it on a different location etc. Now there are lot more stations I can tune to than I thought exists. But there is one puzzling issue. At few frequencies I hear two stations overlapping. Is it possible to separate them?

Will make one dipole also soon.

If the two stations are actually on the same frequency then only a direction antenna (e.g. Yagi) can separate them. If they are on nearby frequencies then a better tuner with narrower IF filters may be able to separate them. If one of them is not really there but created by intermodulation then either a better tuner with a more linear front-end or adding an attenuator to weaken the signal will help.

Thanks again for your responses. I believe it is the first possibility, will have to try with a different antenna.
