nRF2401 communication (extended vs normal) Communicating to the antenna-less version from an extended range nRF2401 seems to produce some strange results... 

At a distance, the receiver seems to receive a number of values instead of one. For example, if I send a 1, I will receive a 1, but 30 times. 

Has anyone had experience communicating across the two models, or is it just best practice to stick to communicating across same models? (Short range &lt;-> short range, long range &lt;-> long range)?
I've run both version fine together

Your symptom of receiving the same value 30 times would be related to a failed ACK, so the sender thinks it hasn't been received and resends it.

I've had potentially similar problems with the power amplified version running at full power causing interference in nearby circuity, try dialling down the power setting on it.
