After reading through the thread I didn't see anyone give pause to the fact of having the transmitter inside a metal case with the only semi clear transmit out the switch placements...
Good point man, and it's true!
However, for those whom, just like me, are going to use an acrylic or plastic case this is not a concern.
I'm poor and married so I'm not going to spend money on a metallic expensive case (at least not before I win in the lottery or get a divorce).
We don't know where the BT module will be placed exactly yet. ATM we are only reserving "room space" to fit our module and battery. Definitely we will need some help into this matter to figure out the best possible position to avoid any interference in the radio signal for those rich
bastards guys that are going to use the metallic case.
I would try to use the case itself as an antenna but I know ahead that antenna is a tough subject (out of my humble IQ limits right now).
I'm taking note of this "possible issue" for the future.
Thanks man!
