Reciprocity?

Where to look is the question?
I'm hearing all of these guys but they are not hearing me.
Same sort of power levels but whereas I'm hearing them, they are not hearing me.

All I can think of is:-
co-channel - i.e. I'm on the same frequency as someone else (stronger),
antenna - I'm using an ATU - tuning for minimum swr to keep the tx happy - doesn't coincide with max rf output though
config - i.e. modulation levels - how to optimise or adjust this - not sure?

I'm using an FT897D, Signalink USB interface and top band dipole + MFJ-949E ATU

Any thoughts gratefully received,
Rgds,
