[Elecraft] K3: KFL3C-200 filter

[N2TK, Tony]

Hi Barry,

Tnx for the info.

Yes, I do like my 200HZ filters. I have one in each rig. When running split when bands are crowded I can have the VFO A width down to 200HZ. Usually I have VFO B wider.

I was trying to find out if the new 200 HZ filters had any advantages over the older 200 HZ filters that you could hear. From Elecraft feedback It seems the newer filters are better but probably you could not hear the difference.

I installed two of the new 200Hz filters in my K3 main and sub receivers a few months ago as part of a major upgrade. Previously my narrowest filters were the 400Hz.

 

I am very happy with the 200Hz filters and find them very good in contests and pile up situations (when on the receiving end).

 

I generally operate split in such situations and transmit on VFO B and receive on VFO A so that I can tune around the transmit frequency and pick out stations with the very narrow filter.

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
