Amateur Radio Rig to Mobile Phone Bluetooth Earpiece

I had the idea of linking a normal mobile phone bluetooth earpiece to an amateur radio tranceiver using a homebrew bluetooth 'enabling' box. After toying with idea for a while, it daunt upon me that the final price for such box would be about USD150... may not be off interest to many of my gangs...

Well, for those interested on the unit still, there's good news and bad news... the good news is that the box is ready for sale... by someone else... checkout the TalkSafe product range from this site. The bad news is that the price is not attractive enough for me... will explore other options still...
