I've been looking at the Software Defined Radios. The SDR 1000
transceiver looks good. Some circuitry for a DC receiver feeding an
analog to digital chip and an RF amplifier. Every thing else is
software. Pretty impressive numbers. Cost with a new sound card is
less than $2,000.
Then there is the SDR 14, basically a spectrum analyzer that can
function as a general coverage receiver to 30MHz. The antenna is
connected directly to the analog to digital chip. Might be nice to
have some front end filters, but basically no RF parts. I'm not
sure what the receiver's numbers are but I suspect with some
tweaking of the software they would be better than anything on the
market.
I've looked at software defined radios and was not impressed. In my
opinion most transceivers are already too complex for most users,
and only a small percentage use them to their capacity. And when you
add the cost of the computer (and it's size) SDR aren't really all
that impressive. The way most computers are built nowadays, they're
noise generators too.
While I own an Orion, I find that I enjoy using my Corsair II almost
as much: No menus, simple operation. I can spend my time on QSOs,
not fiddling around with the radio.
