Developing a HF transceiver around an Arduino

From the YO9IRF blog: "As you probably know, the Arduino platform is a very useful toy for development of electronic gizmos, and after I saw the Myriad RF project I started thinking how a small portable HF transceiver could be developed around the versatility the Arduino provides. The idea is to keep in line with the Arduino philosophy and level of knowledge, so the end product should be fairly simple and affordable, but still offering alot of fun.

 These are my targets:
- 8-band SSB transceiver (LSB: 80m/40m, USB: 20m/17m/15m/12m/11m/10m)
- weight: 500 grams
- output: 10W
- sensitivity: 0.5uV
- consumption: 400mA@13.8V standby / 2.5A@13.8V TX
- display: mode, frequency, step, supply voltage, S-meter, SWR
- encoder VFO with 2 selectable steps
- bandswitch button"
