OK first things first... public apology to Tony as I hit post not save as this should have waited a while but Tony has said fine to blog this and my build.

The Ensemble combines the V6.3 RXTX, PA/Filter kit and USB Interface on a single 2.5 by 5.0 inch circuit board. The USB interface and USB powered Si570 are opto and transformer isolated from the rest of the RXTX circuits and results in almost no USB noise on the RX function. He has included board mounted connectors along one edge of the board making it convenient to mount the board within a metal box. The builder would select a band group, (160m, 80m/40m, 30m/20m/17m, or 15m/12m/10m), at the time of building the kit.

I will have completed a build and this will be on air at the SHARE rally 11th April near Inneskillen North Ireland where I will have a homebrew display and will also be running Simon Browns SDR-RADIO software with this and other SDR projects. If you have a homebrew SDR project bring it along and lets try it out on air.

For those that also like to lay hands on kits before deciding to buy or not I will also have a pair of V6.3 TXRX and V9.0 RX kits I will have built up and a pair as basic kits.
