AGC & DSP Rain Dance

[RLVZ]

Guy-
 
It would appear that some K-3 owners really enjoy dancing around  wasting
time and energy "dancing the AGC up and down" ... and forever fooling  with
DSP adjustments... but there are some of us who do not enjoy that at  all!  
For me,  there are MUCH better uses of time when running  during a contest
than fooling around dancing with the AGC & DSP  settings.  Further, dancing
with the AGC & DSP simply isn't  neccessary in a well engineered modern day
radio.  Therefore,  "dancing with the AGC should be optional for those who
enjoy doing so.
 
73,
Richard
 
 
It may be a dance, but hopefully careful intelligent musing over the matter
 is convincing people that they should get the ambient well down in the  
analog-to-digital converter (ADC) operating range. If they do, a -99 threshold
 is a -109 threshold, and further backing off RF gain can make it a -119 or
-129  threshold as far as the ADC is concerned, and headroom is being used
for what  headroom should be used for.

Maybe the variable gain by band in the MP  (with a menu override) was
really a better strategy for a default. This same  issue dogged Orion
owners, and by the chatter a lot of them never understood  either.   REPLY:
INDEED IT WAS! BUT THE FACT IS WHETHER THE VARIABLE  GAIN WAS SET ON OR OFF
THE MP'S AGC WAS A JOY TO USE AND LISTEN TO.
 
73, Guy.

Richard,

All controls are not for everyone.  There are those who "just want to
operate", and the default setting should be their choice.
For those who want performance enhancement, then several of us are
trying to give instructions about how to effectively do that - because
the K3 does provide those performance enhancement tools.  We are not
making up for deficiencies in the K3 design, but are talking about how
to best use the tools available for extreme operating circumstances.  
These suggestions may not be for everyone.

Those performance enhancement tools will be used differently depending
on the circumstances of band conditions, antenna selection, and operator
preferences.  Not everyone will want or need to use those tools.

Comparing it to driving a high performance vehicle.  If you just want to
cruise the streets, the normal settings will suffice, but if you want
maximum performance on the race track, you will want to use all the
tools at your disposal, and customize them for the track being used and
the driver's preferences (these may be different for every race).  Those
who want to just use the standard setting for this "race" will likely
not come in as front-runners, but they certainly can participate.

Just how much you want to "dance the AGC up and down" is a decision each
owner must decide for him/herself, no one answer fits all.  Use the
default settings if you do not want to make any decisions or do not want
to do any experimenting (trial runs).  In the meantime, the information
gleaned from the various comments here will allow those interested in
fine tuning their K3 to do so in an intelligent and orderly manner.

Well said!

I'm just glad I bought my K3 before I got too involved in some of the discussion on here.   If I hadn't I might not have done it and then I would be missing out on this wonderful radio.

I've experimented almost daily during the last two Winter seasons  
searching 160M CW signals and making a few contacts. Not S9+, not  
loud and crowded Contesting or operating EU from the East Coast of  
NA, but typically weak signals from the middle of KL7.

I'm under the Aurora's influence in a typical S5-7 city noise floor,  
even with 100-150Hz filters enabled and all of the K3's arsenal  
brought to bear. It's typically S9+10-15 at 2.4 KHz for me. I have an  
Inv-L up 70'/out 55' with seven tuned elevated radials, and a  
rotatable Wellbrook receiving loop located on a 120x120' city lot  
surrounded by three power distribution lines. Yea I know - move.

If I only used AGC-on to hear the weak I may as well find another  
hobby. ATT on, RF (IF) gain up or down, doesn't matter. Threshold 08,  
Slope 000, filter gain up or down, doesn't matter. If the AGC (S or  
F) is used, the weak blend into the noise floor. I typically listen  
at a 450-500Hz tone.

However, if I turn the AGC off I can usually fine tune the AF and RF  
levels well enough hear, and usually work all heard. On 160M I've yet  
to hear as well with the AGC enabled as with it off.

Loud signals well out of my noise floor and on higher bands are  
another matter.

73, Gary NL7Y

Fully agree !
Race cars need fine (and often) tuning to get their best for each races, K3's are the same.
But my main main thing is to enjoy and have a lot of fun to chase the weak signal, specially in big pilups in SSB with my exotic callsign. Using for ssb FC: 0.95 and Width: 1.6k (6k, 2.8 & 1.8k filter installed) AGC mainly OFF  in that case and do not attempt I will respond first to the biggest signal.  
Use the N1EU AGC settings   http://n1eu.com/  with good results.
Personal rule: ssb=qro if needed but cw, exclusively qrp max 5w or qrpp.
MIC= MH2 and SONY MDR 7505 Headset, Keys: Vibroplex + straight key Siemens Baumuster T1, both connected.

[Guy, K2AV]

Hi Richard,

The "Dance" referred to the posted conversations about AGC, not
changing settings while operating the K3.  The only time I monkey with
DSP and the AGC is when I'm testing something out.  And before all the
testing the last couple of weeks, I had not changed the AGC settings
in over a year. Likewise I had not changed where PRE/ATT are set per
band since that's been available. I never need to touch AGC or DSP
config settings in a contest. I change the RF gain occasionally as a
band opens and closes, but not really that much.

I am well acquainted with MP's. I would agree with you on the MP's
AGC, to a point. The MP's audio was smooth.  I still own an MP and use
it from time to time (as I do a 75A3 and a Yaesu FT101ZD).  I have
used maybe ten different MP's over the last decade, but it has been
forever replaced as the prime rig by the K3.

At NY4A when we gather for the multi/op DX contest operations, for a
decade we brought in extra MP's to go with Howie's MP's. My MP was the
first one we used out there. We did all the key-click mods, did the
AGC mod where the MP's fast AGC was TOO fast on CW and mushed the CW
in pileups (sound familiar?).  In the K3 that's a setting and a
choice.

There have been 10 different operators out at the DX wars at NY4A over
the decade, all serious contest guys, with wins in ARRL and CQ DX and
WPX.  Among them they owned 9 MP's.

Two MP owners (3 MP's) are no longer active on the bands. The other
six MPs are replaced with K3's. Among the 8 operators still active
there are 7 K3's, an eighth K3 that we hope will be built for the ARRL
DX CW, and one op is waiting for a budget opportunity to replace his
Pro III with a ninth K3 for the diversity on 160. One of the ops
replaced his Kenwood main rig with an Orion II which he prefers over
the K3 but now only brings to NY4A as a backup in case we blow up a
position. We have used his Orion at a run position several times but
most of the ops originally found it hard to get used to, and the menu
RF gain was a never-ending source of confusion the first time anyone
used it. Those of us who have learned the Orion have no qualms about
using it.

Yet six of the seven ops who used both a K3 and an Orion bought K3's.

One thing that NOBODY misses from the MP days is the extra layer of
crud at the bottom of every band added by its RF/IF string. K3
complaints have been dealt with by mods and firmware changes.  Howie
is happy with his two fairly early K3's and has to be goaded into
updating his firmware so that we're all at the same level and don't
lose features we've gotten used to.

73, Guy.

Totally agree! We hams should not be experimenting with our equipment, we should just buy a radio and make contacts. No need at all to waste any time on useless studying the working and technology of our gear. This has totally nothing to do with hamradio.

Hi Paul,
Where is the Ham spirit, even if we are not able today to do our own
equipment as during the past.
Modern Hams became lazzy because technology give us everything on a
plate without any efforts !
May be I'm jurassic but Elecraft waked up my Ham spirit after decades
of using commercial rigs, professionally and on the Ham side.

Maybe I'm not awake yet, but I'm trying to figure out what the differences
are between a KXV3A, and a KXV3 with the KXV3 RXA board. I'm getting close
to receiving a K144XV board (ordered at Dayton) and need to know if I need
the KXV3A_UPGR to work with it, or will the KXV3 with the KXV3 RXA board
work. Its been awhile since I ordered the K144XV (10 months ago) and I seem
to have lost track of the situation. Thanks in advance for any
information...

Phillipe
Mine has 6.0,  2.8,  1.8,  1.0,  and 500hz
I keep dxing every night on 40M with the 1.8 roofer engaged and the DSP set at same BW with the width at 1.0 and what impress me the most is how I can be at just 2Khz away from a signal of 20db over S9 and still be able to pull a 55 to 57 signal from Europe without been bothered by the close station,I have never been able to do this with any of the good radios I owned before.
I am using also the AGC settings of N1EU with satisfactory results.
Like I said,its a total enjoyment to operate this K3

Totally agree! We hams should not be experimenting with our equipment,
we
should just buy a radio and make contacts. No need at all to waste any
time
on useless studying the working and technology of our gear. This has
totally
nothing to do with hamradio.

You tuned in correctly :-)

Jeff,

I am not certain what you are referring to as "a KXV3 with the KXV3 RXA
board".  If you are referring to the RX Antenna, I believe that always
has been a part of the KXV3.  If there was a different KXV3 RXA version,
would someone please inform me.
Yes, the KXV3A is required to install the K144XV - the "A" version has
the switching for the K144XV, and the "non-A" version does not.  I would
say you need to order the KXV3_UPGR so you can be prepared when your
K144XV arrives.

I assembled my K3 less then a week ago, and I don't see where you have to dance around at all. There are certainly a lot of different settings, and I am sure I will spend quite a bit of time finding the right settings for certain conditions. But that is a good thing. Flexibility is good, and once dialed in, you just operate.

The AGC on my Mark-V does operate better then the K3 AGC, at least with the default settings. But then default setting is the key word, as I haven't messed with the K3 settings. From what I read, there may be some changes needed for the K3 AGC algorithms, but unlike some rigs, those changes will amount to a firmware download.

For weak signal CW, I have found that AGC isn't so good anyway, and turning it off on the K3 works magic. All you need to do is adjust the RF gain, and the results are well worth a small effort. So simple a caveman can do it.

Personally, I want all the adjustment I can get. The Mark-V is a good radio, and I still prefer it for SSB over the K3. But, I have found that the K3 Noise Blanker is a bit better then the Mark-V with some QRN, so it will get some use on SSB for sure.

On CW and digital, the K3 just blows the Mark-V out of the water, and every other rig I have ever used.

Maybe the K3 isn't for those that don't want to learn how to actually operate a receiver properly. For those that do know how to use the controls, the K3 is a masterpiece in functionality.

The ergonomics aren't like a full sized rig, so it takes some added effort to learn the controls, but in less then a week, I find it easy to do what I want, and while not as convenient as the Mark-V, when the conditions are tough, the K3 performs. Maybe the FT-5000 will have the best compromise in easy function and great performance, but I don't need another giant brick that I can't take portable, and I sure wont play that much money for a rig.

If it's a dance, it's a dance in heaven. :>)

73,

Bob

The RXA mod had nothing to do with the transverters. It increased the isoation of the receive antenna on the KXV3 board.
 
Jeff, you need to get the KXV3A, and there is an upgrade purchase price that gives you a break and you have to send your old KXV3 back to Elecraft.
