SI 4732 A look inside

Taking the case off the receiver and taking a look inside. Having filmed this and reviewing the footage I can see that a couple of the pins on the Arduino may be bridged. The camera picked this up better than my eyes, when it eventually focused. Whilst the radio board itself seems neat the soldering of the Arduino board and some of the ancillaries seems pretty poor. I suspect the main board is purchased in bulk and then another party soders the ancillaries on, basically building up a kit.
At 2.26 you can see the main chip on the underside of the board. It is an SI4732A10 so it seems I am correct in referring to this radio as an SI4732!
