Wolfgang, The width displayed is the audio width. An AM signal has 2 sidebands, so it is twice as wide as the audio frequency displayed. If you want to listen to AM in a 1.35 kHz width, then it is possible, but there will be few highs, and will likely not be intelligible. You can use SSB

The subject of extra-narrow SSB bandwidths comes up fairly regularly. These 1.8 kHz (and even 1.5 kHz in use out there) bandwidths are not effective for everybody. The older I get, the less I can tolerate these narrow bandwidths for SSB, even in a contest. They give me listener's fatigue. I

Re: [Elecraft] K3 - Filter suggestions for new builder

G'day, 2700Hz and 500Hz in both main and sub RX here. Nothing else, not felt the need, however, an FM filter could be added in one RX one day. There have been measurements which show that the 5-pole filters have superior group delay characteristics when compared to the 8-pole. Regards, Mike

[Elecraft] K3 Filter Selection

Greetings, Just got my new K3 options in Monday and had them all installed by Tuesday morning. I installed 3 of the 4 possible optional roofing filters. They have been turned on and the BW set in config. My problem is when I power down the radio they cannot be called up by tapping the XFIL button.

[Elecraft] K3 Filter Settings

I have 2 K-3's in SO2R configuration with a basic 2.7 Khz and 400 hz filters. When listening to RTTY and the filter is wide open there will be a lot of signals. Turning the filter to 400 Hz the signals seem to just about disappear with only the very strong ones audible/visible. Where am I a miss

[Elecraft] K3 Filter question… Again?

Why an 8 pole filter OR Why a 5 pole filter? Yeah I know the 5 poles are cheaper... but other than that. Phil Santa Fe __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Re: [Elecraft] K3 Filter question Again?

Those 8-pole filters have steeper skirts. Either the 5- or 8-pole work quite well. I use 5-pole for the narrower filters (250, 500), and the 8-pole for 1.8, 2.8, 13 KHz bandwidths. 73, matt W6NIA K3 #24 On Wed, 08 Aug 2012 19:12:58 -0600, you wrote: Why an 8 pole filter OR Why a 5 pole

Re: [Elecraft] K3 Filter question Again?

My thought on the 5 pole was that it would give you some protection but because the skirts were not as steep you could hear someone calling you off frequency better. They would be down but not out. The 5's have slightly less insertion loss and are cheaper. On the other hand they need an offset

Re: [Elecraft] K3 Filter question Again?

Good point. It would depend upon whether or not you'd want to hear someone so far from zero beat. 73, matt On Wed, 08 Aug 2012 23:38:06 -0400, you wrote: My thought on the 5 pole was that it would give you some protection but because the skirts were not as steep you could hear someone

Re: [Elecraft] K3 Filter setting changing with modes and LP pan software

GM Keith: Notwithstanding Joe's comments related to Na3p, I've noticed a K3 software memory problem which may or may not be related. There seems to be two instances of when the K3 appears to loose its mind. (BTW its s/n 2432 using 4.47 and 2.73 FW.) 1st is when I've set up the Norm I and II

FWIW, I had some goofy things happening like this during a contest. I was having trouble tuning my antenna and thought it was just due to ice on it. After the contest was over, I looked out the window to find part of my loop was laying in the snow. That was causing RF in the shack. I no
