Declan, M0TMX was telling me that G7HIF is going to start building a 1w Tait Radio with a Hot Spot board inside the radio. Check out @DStar_Northant on Twitter or see the board and radio on the Tetra stand at Sunday's rally at Cambridge here in the UK. Great to see this. It's easy to see how an extension of this approach could make it easier for repeater groups to put on a D-STAR repeater.
For a small hotspot, around the house, the DVAP Dongle as previously mentioned on the blog looks interesting. I'm hoping I'm going to have a chance to try one out myself in a few weeks time. Will keep you posted. The DVAP plugs into a USB port - connecting to the D-STAR network across the Internet, with its 10mW 144MHz transmitter sufficient to cover 100 feet or so, so that you can use your D-STAR handheld around the house.
