I have been told that this 1W QRP TX from Australia, mentioned on the blog a few days ago, may no longer be available to order. I suggest you email the address on the Genesis website to see if it can be ordered. Certainly some of the SDR transceiver kits are only available in limited numbers. I am sorry if I got some hopes up only to be dashed.
See http://www.genesisradio.com.au/Q5/ . The website gives detailed schematics so you could always "roll your own".
