K3 RX Equaliser SW App?

GM0ELP
This post has NOT been accepted by the mailing list yet.
Hi All,
Does anyone know of a software application for controlling the K3 rx equaliser to specifically create easily adjustable audio filtering toys?

Ideally I would like something that replaces the manual manipulation of individual graphic equaliser sliders with more automated/general filter creation controls  i.e. lpf/hpf(buttons), cuf-off freq (text entry box), peak/notch (buttons), magnitude and sweep (sliders).

I don't have a specific use in mind, other than to be able to use the rx equaliser whilst operating.

I have in the past created cat control sequencies for various filter functions and saved them individually as macros, but useabilty was poor.

Any ideas/suggestions welcome.

Hi Doug,

Some time ago Wayne and Lyle explained that the RX EQ is not meant as an extra "selectivity tool".
It's there to do the last tailoring of passpand response, make up for room acoustics or speaker/hp response. The RX EQ modifies the IF passband and is not a seperate post-detector AF filter.

Notch/HPF/LPF/etc can better (and much steeper) be done with bandwidth and notch controls.

Hi Paul,
   
The bandwidth and Notch should be done at the IF stage not the AF stage, I think everyone knows this. There has never been a question of where it is better to taylor response. Of course it's better to do these things at the IF stage.

I am suggesting a 'cumulative' IF and AF response 'combined'. I could manually taylor (approximate) any required AF response using CAT commands and the available 8 audio bands and gain/attenuation levels. Why wouldn't software be able to do that? It's not a question of how steep the slopes are, its a matter of using an AF feature in the K3 to augment the IF performance.

If there was a software tool available to approximately track AF to IF response would you try it? I would, and I think it is possible. Can you give me a reason why it isn't possible?

Hi Paul,

Yes, I would also like to see firmware RX EQ by mode, but I've been told
it's a long way down the Elecraft to-do list due to complexity. However a
software approach opens new possibilities limited only by the CAT port
speed.

By AF I mean the 50,100,200,400,800,1600,2400,3200Hz bands in the RX EQ
menu. I would like software to remove the manual drudgery  (speed up
operation) of me having to manipulate an 8 band graphic equaliser for common
AF responses i.e. peak and notch check boxes and a sliders for width, ref
level, magnitude and frequency.

I suppose the usefulness of any such software calls into question the
usefulness of the RX Equaliser in general.

Doug

I use K3-EZ to do this sort of thing:

Hi Paul,
    The rest of my post gave reasons why K3-EZ isn't the right solution for me, but thanks for the suggestion. In reading the content of the K3-EZ link you gave, it says that K3-EZ doesn't work with LP-Bridge. This is also a bit of a show stopper for me as my logging and pan adapter software are normally running on my PC.

The reason for that Doug is that K3_EZ does its stuff by manipulating the K3 menus by software. That is the only way to read or change the EQ settings at the moment and that is not a good thing to be doing while logging, panadapter and other software is running due to a potential conflict with the up / down commands used to change the menu settings.

So the short answer to your original question is no, such an application does not exist because the K3 does not support a way to get / set the EQ settings that can safely be used during normal operation.

Doug,

I didn't see the start of this thread, so I'm not sure what you're
seeking, but have a look at K3_EZ at:
http://home.roadrunner.com/~n2bc/SW.htm

All sorts of things you can set with it, including the equalizeers.
