K3 Feature request

If you happened to read W3IZ's review of the FTDX9000MP in the July QST you will find an interesting comment on page 46. I don't know what it is but I want it on my K3. Here's the quote:
"When activated, the contour acts like a super duper ninja CW filter that makes the desired signal sound as if it is the only signal on the band." 73, Mike K2MK |

Er, try "xfil"? Or the "width" knob?

Mike, The contour is nothing more than a Notch/Dip filter or a Peak filter (you can change it's function in the menu). Basically you center the "contour" in the center of the pass band (pitch freq) and you can set it to either Push up that signal (no different than if you set your Pitch freq. to 400hz and went into your RX EQ and turned up the EQ 400Hz setting to +1 - +16) or suppress (Turn down your 400Hz -1 to -16 on that freq.) the pass band area. The reason I chose 400Hz is because unlike the contour which can variably move through the entire pass band area (600Hz - 900Khz) , with the K3 you only get a specific Freq. settings for each EQ setting.. 400Hz happens to be one. I belive there's another for 800Hz as well.. If you can stand to listen to your CW tone that high... So there you have it.. You have a Suedo Contour feature on your K3 already... If you need further explaination please feel free to email me off the group...73 > Date: Mon, 21 Jun 2010 05:46:33 -0700 > From: [hidden email] > To: [hidden email] > Subject: [Elecraft] K3 Feature request > > > If you happened to read W3IZ's review of the FTDX9000MP in the July QST you > will find an interesting comment on page 46.

In CW mode you also have DUAL PB which tracks your PITCH setting. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Actually you can't do that with the K3 at narrower bandwidths in CW. The RX EQ is deactivated at narrower filter settings. (Unless this changed in a recent firmware release). I don't recall what the cutoff width is and I can't find it described in the latest manual.
There is also a minor annoyance with using +db settings in the RX EQ for CW because as the filter width is decreased, there will be a noticeable decrease in volume when you hit the point at which the RX EQ is deactivated. Also as you indicated, 400Hz or 800Hz for peaking may not be everyone's cup of tea. Maybe this is a good time to suggest an adjustable audio peak filter. 73, Mike K2MK
