AF-1: First Impressions

Happy New Year Everyone!

I started and finished my AF-1 this evening. It was an easy build; I was finished in a few hours. The tests worked out OK and I have been enjoying tuning around on my K2 to see what it will do for me.

At first, it didn't seem to do much. Then I started to get the hang of tweaking the controls and now I'm very happy! I haven't had a chance to use it in crowded band conditions...maybe some morning soon on 20m. It does help bring the weak ones out of the mud though.

More as I get a chance to work with it further. Tomorrow's the first day back to work after the holiday, so now it's time for bed!

73,

Re: AF-1: First Impressions

Ken,

I found that the AF-1 is really great for CW signals - it really lifts
them up out of the grass. I hope you find you get good value out of yours.

KDSP2 - Now What Have I Done?

In reply to this post by Ken Alexander-2

Fat, clumsy fingers; that's what I've got!

I decided to start on one of my Christmas holiday projects tonight: learning how to find my way around the KDSP2 in my K2. All I have ever done was accept the default settings since I got it, but have always had the feeling that the denoiser was too aggressive for my taste. I also wanted to see what settings could be tweaked, and once and for all, I wanted to find the darn clock! (I found it. I'm glad I own a watch!)

Anyway, to my fat clumsy fingers problem.

I was messing...er, experimenting with the CW filter settings. It was set to CF1 at the time. I think I was moving through the menus. The last thing I saw (I think) was LPASS. Clumsy finger hits a button (I don't know which one) and now CF1 is impossibly narrow and has a brick wall cut off at about 500 Hz. It doesn't roll off as you tune down in frequency (on 40m) the audio just stops! CF2, CF3 and CF4 are not affected.

Long story short: I messed something up and I don't know what I did. And I find the instructions that come with the KDSP2 impossible to understand. Any assistance would be very gratefully accepted.

Thanks and 73,

Ken Alexander

Re: KDSP2 - Now What Have I Done?

Ken,

Yes, the KSP2 menu entries are a litle bit clumsy, but if you follow the
directions you can get it done. I know you will hae to fumble your way
through them 3 times before it seems OK.

Specifically, to get CF1 back to the LOPASS setting, Tap DISPLAY to
bring up the KDSP2 menu - the first letter of the displayed menu is the
mode, and the number is the filter. If not correct for the filter you
wish to change, tap MODE or press AFIL until it is correct -- yeah, I
know, you have to tap DISPLAY each time you want to check it, the DSP
menu is not "sticky".

OK, so you have C1 nr nt on the display - hold the RCL button to move to
the next menu. You should see something like C.1 .60 .80 on the
display. Note the position of the blinking dot - that is the parameter
that may be changed by tapping the BAND+ or BAND- buttons. To move the
blinking dot to the other parameter, hold the STORE button.

In the case of the CW display, the first number is the center frequency,
and the second is the width. To get the LPASS filter in CW, increase
both the center frequency and the width to their respective maximums.

Re: KDSP2 - Now What Have I Done?

That did it Don! Many thanks!

Somehow, my first filter setting was: C1 1.35 .75

I don't know how I managed to do that! It requires more button presses than I thought I made! Anyway, it's fine now and I'll proceed more carefully from here on.

Thanks again!

Ken, VE3HLS
