Well... nothing wrong with this if it's sold as a prototype. The
problem is that many are pawning these off as production units. That's
not very smart for this type of RF device. Between the variation of
components... mixed with the variation of physical assembly of those
components (because of no real PCB) you can get all types of
performance and instability issues.
