[Elecraft] K3: KRX3 hearing no Signals

For future reference for people searching as to why there KRX3 is not 
hearing any signals be sure the filters are installed in the slots they 
are supposed to be.  You will have noise and the sub controls will work 
but you are not hearing any signals.  I know what I am going to write 
sounds simplistic but read on there is more to it than one would think. 
  I am well aware of filter placement as I have put together two K3's 
and as I was putting the KRX3 together my XYL Edith W0OE mentioned the 
manual information that the widest filter needs to be first.  It does 
not have to be in FL1 but it has to be first.  I told her "THANKS I AM 
AWARE OF THAT"!  How I did it I will never know but I proceeded to start 
with the wide filter in FL5 and then FL4, FL3, FL2 leaving FL1 open. 
Somehow in turning the board back and forth I messed up.

I suspect the root of the problem is that most of us are used to working
left to right, and the K3 filter layout in the rig is right to left. 

Yours and other comments have me thinking that in the next update I'll
redesign the table so, instead of going down the rows FL1 through FL5, it'll
be laid out horizontally with FL1 at the *right* and FL5 at the left end,
just as they are laid out in the K3 and KRX3, with the bandwidths and
offsets on the rows under them.
