New AGC FW

*Hi All,

I have been testing the new settings available with the new FW.

The original settings allowed setting the AGC from 2 thru 8. The new
settings allow you to increase the delay of AGC onset from 2 through 20.

The effect you *hear* is that QSB becomes more rapid (expected behaviour)
but the clarity of multiple signals becomes much clearer. As an example,
tuning into the pileup of stations calling 7O6T enables each of the
callsigns of the stations is much easier to pick out. I have not detected
any mushy audio effects using a setting from 14-18 but occasionally you get
a louder audio from some stations.

I noticed you do have to reduce your AF gain somewhat to compensate for the
increase in audio but you do this while you adjust the AGC. I have been
using PF2 to switch between normal use and AGC adjustment for convenience.

On 10M I had some QRN appear and activated the NB and found the NB
eliminated the noise completely but did not notice any audio artifacts in
audio from strong signals. I have settled on a setting of 12-14 for normal
use now and I am evaluating whether this should become my *normal* setting
for *daily* use.

I will leave it to Wayne to respond with the relationship of the new
settings to S units but it appears to me that this improvement should
resolve many of the issues experienced when working a pileup with even more
refinements expected in the future.

My observations are a work in progress and I am sure others will alert the
group as they have a chance to play with the new FW.

regards,

Gary

Re: New AGC FW

Gary,

All you said is true --- BUT

I am not trying to be argumentative, but the AGC adjustment that has had
the range increased is the "Threshold" and not the "delay" I would not
necessarily bring this up, but there *is* a menu setting for AGC DLY,
and I do not wish to see owners confused between the Threshold and the
Delay.

In simplistic terms, the "Threshold" is the RF level at which the AGC
begins to be active.

Re: New AGC FW

*Don,

Correct...forgive me for the *brain fade*...yes the new adjustment IS for
the onset of AGC as you point out. My observations still remain as stated.

Apologies to the grout for my tardiness in explaining what I am
seeing/hearing.

I will repeat that the muddiness I had before is now not apparent, at least
to a level that it was and signals are now much easier to make out.

There are some limitations with this FW but that is also being looked at by
Elecraft but I will leave that for the folks at Elecraft to explain.

Regards,
Gary

Re: New AGC FW

Gary,

No problem - my goal is that no one become confused because of terminology.

What you report is great news. This has been a mystifying thing at
Elecraft for some time because of the difficulties of testing the
results of any changes.

Thank you for your efforts and comments.

Re: New AGC FW

Don, Gary and the group,

Wayne's earlier comments about the noise blanker working better turns out to be an understatement to say the least. Not only has the clarity of signals improved by being able to tailor the onset of the SW AGC to start at a higher level and clean up many of the artifacts that created problems before, but it also allows the IF noise blanker as well as the DSP noise blanker to work more like most people's concept of what a noise blanker should be able to do and now does it with FAR less distortion to the desired signals. This includes using heavy blanking with strong signals close in.

I've now been able to eliminate some stubborn power line interference that has been plaguing me for a couple of weeks and due to recent tornado damage a few miles South of me, the power company has not had time to find and cure it yet. They've been busy replacing the temporary lines & poles they used to get everyone back on line as quickly as they could after the storm.

Now that they are on the right track, I'll bet there will be quite a few more improvements to come.

Re: K3 New AGC FW

Loaded the new SW and I miss having NR. I have been tuning around in
the 7O piles and it is hard for me to compare as I never really
experienced what others have. I need to split the antenna and share
with two K3's and see if I can hear a difference.

Glad to hear the NB is working better. The distortion to some signals
with it on was really bad.

Re: K3 New AGC FW

All noise blankers cause some distortion -- it's a matter of degree.
NARrow blanking pulses and lower DSP blanker settings will cause less.

I'm surprised the AGC changes are having this much of a benefit, but
I'm not going to complain.

Re: New AGC FW

In reply to this post by Jim Sheldon

*Bob,

I concur with all your observations. This is the largest FW improvement
effecting all styles of operation that I can recall in quite some time.

An S3 noise on 40M this morning was easily eliminated and then a local Ham
travelling by was 30db over S9 and I noticed the lack of distortion
previously experienced prior to this upgrade.

Now we need to be patient to see if the auto-notch feature can be enabled
whilst running the new settings.

regards,
Gary

Agreed but not too patient! The new settings seem to work find on SSB
but the loss of auto-notch is the one big miss.

Re: New AGC FW

Ok. Silly question. While I understand that the k3 and the kx3 are different implementation, software wise. When should we expect, at least a beta, of this new feature on the portable?

Not that you want me to be a beta, just asking for the group.

And sorry if it has been asked before

Re: New AGC FW

I guess the question is: Is this already implemented, or its equivalent,
on the KX3? 73, Guy.

Re: New AGC FW

Not yet. The K3 AGC firmware improvements have only just now been created
and are out for testing in the field. Wayne has already indicated that the
KX3 will benefit from the work in due time.

Re: K3 New AGC FW

In reply to this post by wayne burdick

My question would be whether DSP log and antilog functions are not used all
over the place, not just the AGC. 73, Guy

Re: K3 New AGC FW

Administrator

These particular functions are used *only* as part of the AGC
calculations. They have to be very fast since they happen in the 48-
kHz interrupt handler.

Re: New AGC FW

In reply to this post by Gary Gregory

Glad I did not sell my trusty ancient Timewave 599 Plus...
It will be my personal auto notch temporary workaround until
the code catches up :)

Plan on playing with this tonight. The improvements sound
quite encouraging! I'll make some recordings while I play.

Keep slinging that code, Wayne and Lyle!
