nRF24L01+PA+LNA module

• These modules are LNA = Low Noise Amplifier models, supposedly good to 800m open line-of-sight.
• I have two nodes (from nRF24-1 Project) working with the standard modules, and I just plugged in the LNA modules instead, however they didn't communicate at first. Preamble printed, so they were functioning and recognized by the Uno, but communication failed.
• Then discovered an anomaly:
  When the preamble in my sketch prints out module details, one of my LNA modules comes up as: "nRF24L01", while three others are: "nRF24L01+". (Have not yet tested others)
  When I have two "+" models in the nodes, they work, at least sometimes, however other weirdness is going on, because sometimes a given node will be able to receive and send a response, yet when initiating a message, it fails. BFM.
• And another weirdness:
  I have a bunch of these modules, and have been inventorying and testing them. One module, when first tested a few days ago, showed in the preamble to be a model "+". But now model reported without the "+" and indeed it doesn't communicate well.
