The radios are the same and the power supplies to the radios are the
same. Indeed switching the radios gives the same effect.

The radio outside is likely being desensitized by some other signal.



Most likely scenario.

Also make sure that in your design you are powering down the transmitter
fully in the receive mode. In some radios there can be a residual
carrier from the PLL causing self interference ar interference to other
nearby nodes.
