[Elecraft] Looking ahead to Field Day - roofing filter question

[Julius Fazekas]

Bill,

In my CW opinion, I would say you don't need a filter for FD use. While popular, it doesn't hold a candle to the harsh conditions during a 160M or major DX contest, such as CQ WW on 20M.

The 500 Hz filter is a good choice for general contesting and semi-crowded conditions. For casual CW, you probably don't even need a special CW filter with the K3.

The beauty of the uber-narrow filters in excessively crowded bands is that you can really kill most of the garbage outside of your filter's pass band. 

I think it's been stated here before, unless you have serious needs, like contesting, the K3 does great bare bones and added roofing filters are not necessary.

I'll be hauling my K2 out for FD, love the "all-in-one" QRP package.

73,
Julius
