G'day again

Sorry but, to use the Australian vernacular, I 'stuffed up' on the email 
address for the American QRP Club - it is www.amqrp.org

The exact URL for the SoftRock-40 receiver is:

---------------------------------
G'day

If any Orion users (or anyone else) on the reflector have been following 
the above thread and would like to try out the SDR-1000 software on air, 
using their PC, there is a dead cheap way of doing it.

The American QRP Club is selling a bare-bones software defined receiver for 
40m for a massive $23 which uses Flexradio's PowerSDR free open-source 
software .  This uses a quadrature mixer, plugs into the USB port of your 
PC and delivers an I-Q audio signal into the PC's sound card.

The little receiver has a claimed MDS of about -128dBm and a sensitivity of 
around 0.1uV (? - I think).   It has been designed by Tony Parks KB9YIG and 
Bill Tracy KD5STD - see www.amqrp.com for details.  A friend of mine has 
just bought one and is having heaps of fun with it.

Incidentally, I don't have an Orion or a SDR-1000....  Lots of boat anchors 
here...
