Help wanted !
Do you have a reference for a bluetooth (I'm also taking refs for whole zappers running android but needs to be cheap) barcode scanner, that can scan pretty much anything, BUT that have a GOOD narrow window to not be distracted by nearby other barcodes ?
RT welcomes etc.

Microwave magicians, do you have literature discussing the effects of temperature inversions on the C band propagation?

We've been recently impacted by some unexplained fading on a 28 mile LoS terrestrial link (3660 ft MSL on one side, 5550 on the other) that has been stable for months.
