[Elecraft] ADT-200A Fully DSP transceiver

[Eric Swartz - WA6HHQ, Elecraft]

It looks like a nice mid-performance rx, minimalist user interface, 
design. Though at 4,600 swiss francs (about $4,351 U.S. plus shipping) 
it is pricey for their level of rx performance.

At 50W it will not have enough drive to drive most legacy tube based 
amps to full power, especially the widely used 3-500z based legacy amps 
from Heath and Ameritron.

A few comparative Rx numbers from their web page versus the K3:

                K3     ADT-200A
IMDDR3        102 dB     96 dB 
Blocking DR   140 dB    112 dB   (desenses 28 dB earlier than K3 RX)
2nd Order IP  +79 dBm   +60 dBm  (IMD from out of band sigs 19 dB worse 
than K3)

It is an interesting design with some unique ideas. It will be fun to 
see where they take it over time.

Of course, we'll keep improving the K3 too! ;-)
