Great question Pete, I thought I would offer my experience as a 'cannon 
fodder' part time contester. (100w to some low wires in the centre of 

I had my Mk5 (With Inrad's) and K3 side by side for almost a year and for me 
the K3 wins hands down as a contest radio.

I love the Mk5 and I was really comfortable with it, under usual DXing type 
operation I found very little difference.

However when it comes to contesting on crowded bands, like the recent RTTY 
and CW contests, the K3 allowed me to work stations I could not decode/copy 
with the MK5.  The K3 seems to be able to filter out so much more of the 
unwanted signal and that for me meant more Qs.

There is nothing I can do about antenna's at this location so the K3 has 
been a means of improving my QSO count.

If I had the money and space I would have both in the shack but sadly the 
Mk5 has now been sold.


Jim,  MM0BQI
