After extensive tests with the new APF feature, I can say the results in
digging out weak CW signals are impressive. I was so enthusiastic that I
forgot about the SSB contest this weekend and concentrated on CW! The fact
that it is independent for the main and sub receivers is a very useful
Thanks for you ob's Richard.
Well perhaps the powers to be can secretly have a look-see at the variable Q
and IF they collectively think it's well worth the mod then, 'make it so'!!!

Wayne released APF to Field Test last night and also said it was OK to post
comments. It seems to work very well and I expect it will be released
publicly soon.
APF (as implemented in the FT-1000) has always been a weak signal receiving
tool. It's not for adjusting PITCH or some of the other
Great Bill,
This is the only reason I have kept my Alpha Delta VRC speaker. As before,
the peak filter always did what xtal filters and DSP could not.
With the EME contest this weekend, perfect timing for me too.

Hi,
I am a bit impatient waiting for new beta firmware, WAYNE, WAYNE??

I agree with Bill. I've had a chance to preview the APF function and
it seems to operate very well although I haven't seen a any really
weak stations like 5R8RJ on 160.
APF as implemented by Lyle may become an alternative to a very narrow

Yes, I realize that. I would like to compare what is heard using the
APF filter to what is displayed by BeaconSee with its sub-noise signal
recovery algorithms.

APF has a very significant improvement on weak signals in the noise.
I completely agree with prior posters. HOWEVER...
I would like to be able to ***VARY THE Q*** with the width control and
LEAVE IT ON with a mild Q, and sharpen it as required. If I can back
it out to 2 dB with a width

I agree with Joe on this. The bandwidth of a CW transmission is narrow and
Nice job guys...all the previous FT-1000 owners will rejoice!

Being a former owner of several FT-1000D radios, and one left in the shack
on the shelf next to the K3 which is in the primary position I have
to agree,

I don't give a hoot about resurrecting an FT1000D, I need the
variability. I stand by what I said. The goal is whatever Wayne
makes of it. He's the only one I'm trying to convince here. 73, Guy.

Hi all,
We'd like to get a lot of feedback on our current APF implementation
before we make additional changes. Variable Q is one of several
possible enhancements.
Keep those cards and letters coming, but holster your weapons :)

Variable Q might be nice, it seems a pretty good compromise as is though.
the issue I would have with putting the Q on the width control is that
this then prevents the user altering the IF filter bandwidth when the
APF is selected
Currently I am finding that I am still playing with the IF width
Thank you very much for that small favor :-)

You can choose to use the extra peaking it provides with a little more knob

or choose to not use it. Ask how many 160 meter contesters will use it !!!
If you are a CW contester I guarantee you will choose to use !!
