The screengrab pictures are sure pretty. *Any idea how they satck up
against the comp?

I think it is trying to compete with the Perseus. Don't appear to be
any prototypes floating around. The earlier WR-G313e has lower dynamic
range but the numbers on this model look promising. Hopefully QST or
Sherwood Engineering will test one when they are in production and
verify the numbers.

I volunteer to test one!

As far as numbers go (at the Sherwood site), the Elecraft looks plenty
hard to beat. *I wish they just made a stand-alone RX. *I'd even buy
the kit, and hopefully not screw it up!

I inquired. *A lot of the receive path goes backwards through the 10
Watt exciter board (filters, relays) and it is not feasible to offer the
radio without it. *For General Coverage you must add a wide IF filter
and a second set of input bandpass filters. *A little under $2K for a
radio that runs circles around many costing 2 or 3 (or more) times that
much money. *I suggest getting a General Class ham license (no code
required since 2007) and adopting a K3, if you have a true passion for
pure radio.- Hide quoted text -

Thanks for this. If I feel wealthy one day, I might just get one and
not use the transmitter (really no desire at all to talk back ;-).

Nice case. All the brains are in the user provided PC. The display and
control software is free.

They still need some fairly expensive analog components to prevent
overloading the A to D converter. For instance in the Perseus there is
an analog front end with a pre-selector, pre-amp, and attenuator.
