Make sure both your radios are locked to the same clock source. Any fsignificant requency offset between the two is going to ruin your correlation peaks very quickly. Frequency offset is going to end up as a progressive phase shift along your PN sequence. If that phase shift is a non-negligibe part of the unit circle during the time of your PN sequence, they won't 'add up' to a peak anymore.
