[Elecraft] K3: advice about options to buy?

[David Cutter]

John says he is a casual operator, ie not really interested in contests.  I 
suggest any additional filters (apart from the General Coverage BPF ) are 
probably unnecessary for his style of operating.  As I understand it, the 
filters are not there to determine the operating receive bandwidth, but are 
to protect the A/D from overload.  This overload is unlikely in his 
operating environment, ie not contending with super - heavy QRM unless he 
has a very close neighbour who persistently creates that sort of signal. 
The K3 has a superb adjustable DSP filter that goes all the way down to 50Hz 
with little or no ringing plus the new APF for very small signal 
enhancement.  Save the money and spend it on something else like the 
auto-atu which is superb.

My 2d - keep the change
