[Elecraft] K3: KFL3C-200 filter

[N2TK, Tony]

Tnx Ian,
On 80 and 160M this past weekend had the filter bandwidth set at 200HZ most of the time due to the QRN. The NR helped a little. Just trying to find out if worth the money to buy the new 200 HZ filter if I would really know the difference.

The new filter has 6 poles and steeper sides than the older filter thet have only 5 poles. On my K3s I have also the 500hz 5 poles. I excluded the 8 poles filter becouse on a previous experience on my old FT1000MP  with the great 400hz ‎paired filter by Inrad found them a little tiring on long listening - more poles, more ringing I think.
I think that the new 200hz 6 poles is very good: I used it 48 hours CQ WPX and yesterday CQ WW CW, great radio and filters test,  without tiring my ears.

My understanding is that the new 200 HZ filter is different than the old 200 HZ filter. Is this correct?

If so, is the difference even possible to detect on the air? 



Tnx
