[Elecraft] K3 & AL-80B

[Tom Fitzgerald]

I use the ARB-704 Ameritron interface with my AL-80B and Drake L-4B. Better 
safe than sorry. I think they are now $59.95, used to be less than $40. Still 
cheap insurance for a $3K radio IMO. 73, Tom kd0bcf

[Elecraft] K-3, N1MM, MK2R+ setup assistance requested

[Milt, N5IA]

Esteemed Reflectees;

I have historically done my SO2R operating with a pair of FT1KMPs and a home 
brew black box constructed from the directions in the NA manual.  I used NA 
as the logging program.  It all worked VERY well.

Recently I have upgraded the primary contest radios to Elecraft K-3s, and 
the logging computer to one which does not have com ports on it.  I have 
also started using N1MM as a Windows base logging program.

So, nearly the whole combination is new.  I have been unable to get my 
"black box" to work with N1MM and and USB to serial adaptors.

The reason for this message request is for someone out there to assist me so 
I don't have to totally reinvent the wheel with my new acquisition.

I have taken the plunge and purchased one of the MicroHam MK2R+ devices.  I 
have set it up as near to the instructions in the MK2R+ manual and the N1MM 
manual that I can discern.  I find both manuals not totally in tune with the 
other's requirements and I am sure somewhere I have checked a box that 
shouldn't be or failed to check a box that should be checked.

I have the radios talking to N1MM and I have both TX and RX audio passing 
through the MK2R+ box.  What I have not been able to make work is the PTT 
and the audio codec recordings for SSB.  I have not yet tried to set up CW 
or RTTY.

So, after all that explanation, is there someone(s) out there who might have 
this combo playing that could give me some direction of what to look for 
that is causing the lack of PTT response and how to make the audio codec 
recordings play.  I am using the Heil Pro headset.

Ideally, I would like to call someone on the telephone who has this combo 
working and go over the setup step by step until the problem is discovered. 
Anyone out there fit the description?  If so, reply to me directly with your 
contact info and availability timing.

Thanks in advance for any assistance.

Milt, N5IA

Re: [Elecraft] Roofing filter for CW

[Bob - W0GI]

I don't think it is hype, as the 8 pole filters have steepers skirts, but in
practical terms, do the steeper skirts buy you much? I do know that the 250
has a lot of loss. 

I keep hoping I can find a 500 for $50. It would be a nice addition to the
250. :>)



<<
I find that both the 200Hz and 500Hz filters work just fine. I decided to
save $50 and not buy 8 pole filters. I think the 8 pole hype is somewhat
just that. I have a 2nd 500Hz in the second RX.

Re: [Elecraft] 2nd Receiver Question

[WILLIS COOKE]

The sub-receiver comes with a BNC jack that can be used if you don't have an 
antenna tuner or if you don't want to use the second SO239 on the tuner.  The 
receiver mutes when you transmit, but is fast enough that you can use it when 
transmitting QSK.  It does pop a little when QSK but is only a little 
annoying.  You can receive on the transmit antenna or the receive antenna, your 
choice.  If you want to use a transmit antenna for diversity receive, you need 
the tuner.   The top antenna jack is connected through the main connector to 
the sub receiver.  You connect the second antenna with a supplied coax jumper 
to the tuner or with the cable connected to the supplied BNC jack.  You 
can connect either, but not both at the same time.  I agree it is confusing, 
and it is hard to describe, but we seem to figure it out when we have the parts 
in hand.

[Elecraft] P3

[rfenabled]

Does anyone know EXACTLY what it WILL do NOW?

Where are the specifications to be found?

What is the "FUTURE" feature set going to give us, the customer?

When I know the answers to the above I will be able to evaluate the P3, but not 
before then.

So I will remain in the undecided column of "Prudent" people wanting to know 
what DO I GET for my hard earned pittance excuse for a salary...(:-))

Till then, I will wait. No rush here to be the first and go through all the 
teething issues and flurry of FW upgrades/updates and HW changes likely given 
the recent past history.

Re: [Elecraft] Kenwood's Future

[eric manning]

One of the K2 owners has worked in communications equipment marketing
for many years. He told me once that he absolutely hates the ham market 
segment because
we are never satisfied and are extreme cheapskates.

 [I prefer to call it the amateur spirit of doing a lot with a little - 
the junkbox tradition -  and continuously improving
our gear  - until something breaks.]

Anyway, because we are such a pain in the pants, maybe Kenwood will get 
out of the amateur market segment.

Hector,

What settings do use to get such good NR results on SSB?

I think you might be overlooking the "toy" factor of owning the P3.  I think it 
is a cool and neat toy so I am buying one.

You don't need it at all, but it is nice. I am tuned on 40 right now, and
just brought up the callsign screen on CW Skimmer. I have a list of 30
callsigns that are in CW QSOs right now. It would take a while to do that by
tuning up and down. and waiting for each " de ".

I have been doing it without a computer for 35 years or so, and will
continue doing it that way at times, but there is nothing wrong with using
tools that are available, and CW Skimmer is a great tool.

As for expense, I got an LP-Pan off of EBay for $135, and it goes to a PC
and Soundcard I already had. The best $135 I have spent for a while.

Re: [Elecraft] For you Anti-Scopes

[Bob - W0GI]

After feeding the K3 IF through LP-Pan, then to PowerSDR-IF and CW Skimmer,
you don't have to convince me.

As a matter of fact, I am pretty blown away by how everything goes together
so well.  With LP-Bridge running the K3 RS232 management, I don't even have
to worry about shutting one program down to start another. PowerSDR-IF, HRD,
Skimmer, K3_EZ, and K3_Util are all assigned to virtual com ports, and you
can run them simultaneously if you want.

My favorite is CW Skimmer. With the "Audio IF" setting at -4174, I click on
a text of a signal, and it tunes the K3 to zero beat on that frequency.
Ready contact that station instantly. It just doesn't get much better then
that. :>)

I have a 22" monitor and an Intel i7 quad core, so no problem with CPU.

Those $10-12K radios can't hold a candle to this setup. And it is not that
expensive.

Re: [Elecraft] For you Anti-Scopes

[Ken Alexander]

Oh my goodness!

What are we talking here for a P3, somewhere around $700?  I'm supposed to 
spend that kind of money to find people on 40 metres in the early afternoon?  
It's cheaper to tune through the band with a wide filter selected.  And if I 
miss someone, good heavens, is it really the end of the world?  If I'm looking 
for DX it's easier and cheaper to check a DX cluster.

A scope might be handy in contests, so that makes it useful to me maybe 6 to 8 
weekends a year.  No sale there either.

This afternoon I could hear the 1 watt signal from the NCDXF 20m beacon in 
Hawaii.  I could also hear (weakly) the 100 mW signal from the NCDXF beacon in 
South Africa with my K2 and a vertical...so you can probably guess my opinion 
on amplifiers.

Re: [Elecraft] K2 maiden flight

[2rGarry]

You said: Quote: I did order the NB module yesterday, tho, as the rig is
basically unusable at night now due to the line noise. I believe that's the
last thing I really need to add to the rig. Unquote

Congrats once again on the K2 and the QSO.  I don't have the noise blanker
and unless I go mobile don't expect to have any need for it but it seems I
have heard that it is not effective on anything other than ignition noise. 
I hope you don't find that to be the case.  Possibly the DSP unit would
serve you better for help in conquering the noise issue although back when I
owned a K3 I did not find the DSP in that radio to be nearly as effective as
I had hoped.

I confess to being extremely fortunate where I live as noise is seldom a
problem and I find the K2 to have a very nice quiet receiver.  When I had to
deal with considerable noise, some time back, I discovered that using a
magnetic loop type of antenna for receive was a very effective way to reduce
noise that I could not otherwise eliminate.

So far I really like my K2, qrp version for cw

Re: [Elecraft] Is NR effective on ssb?

[Bob - W0GI]

I put the BHI DSP unit in the FT-817, and was amazed at how well it worked.
It is the best audio dsp I have heard.  As mentioned, it isn't great for CW,
but somewhat usable on the lowest strength.

I haven't had much of a chance to really try the K3 NR on SSB, but NR hasn't
really pulled any signals out of the mud in my experience, but makes them a
lot easier to listen to.

<<<
BTW, the GAP product is the same thing to the BHI units; just rebranded for 
sale in the US.

Re: [Elecraft] Is NR effective on ssb?

[O. Johns]

David,

This is exactly how I would describe all the audio A-B examples I've seen/heard 
posted on the web, including Hector's and the ones with the LINGUA audio 
processor posted by Juergen. 
 

Maybe that is all we can ask.  Oftentimes, when I'm tired and the band is 
disappointing, the noise begins to sound TO ME like speech.  If a human can't 
tell the difference reliably, how can we expect a DSP to do so?

For me, in my very high noise environment, even with the RF gain backed off, 
the noise interacts with the NR to give a hollow ringing cavern effect with the 
voices at the very back of the cavern.  Unless the ssb signal is pretty strong 
in the first place, the NR does not improve my experience.

But I'd still like to learn how to do it.  If someone in a similar high-noise 
environment has found the magic settings, please post them for the rest of us 
to try.

73,

Oliver

[Elecraft] K2 noise blanker and sensitivity

[lstavenhagen]

Hi all,
Speaking of the NB, mine is on the way now from Elecraft and I had a quick
question.

I read somewhere a long time ago (perhaps in the archives here of the
reflector) that the NB module reduces the sensitivity of the RX in the K2.
My questions are

- if so, by how much (i.e. is it noticeable)
- is it all the time, or only when the NB is enabled?

Just curious,

Tnx es 73,

and just got off the phone with Elecraft - they are shipping
May 2009 orders now so .

Re: [Elecraft] Is NR effective on ssb?

[K2QI]

Hi John - that product performs very similarly to the GAP ANEM at a much
lower price.  The technology is the same.  In fact, the GAP ANEM performs
significantly better than many other IF based DSPs including the one in the
K3.  I somewhat regret having sold the ANEM now, but with Lyle's
modifications to the firmware, K3 DSP performance is getting a little
better, but still quite far in terms of what I consider ideal.

The downside to the ANEM and many other AF based units is that it will not
work properly with CW.  The algorithms used in the ANEM are only effective
at isolating speech waveforms from noise signals.

The link to the ANEM is here: http://www.gapantenna.com/hearit_nem.htm

BTW, the GAP product is the same thing to the BHI units; just rebranded for
sale in the US.

73 de James K2QI

*Disclaimer: I don't work for GAP or BHI, but do know a good product when I
see/hear it.  This is a good product.

Re: [Elecraft] K1 VFO Range Question

[Rick Dettinger]

Hi Curt,

I like the 150 kHz tuning range.  Mine is actually 170 kHz, which, of  
course, gives an average rate of 17 kHz per revolution with the 10  
turn pot.  I think this is still slower than the top rigs of my youth,  
which we though was quite good.  I don't remember hearing complaints  
about the Drake and Collins tuning rates, which, IIRC, was in the 20  
kHz per turn range.  Of course, they did have larger knobs.  I put a  
K2 knob on my K1, but I don't think that was necessary.  I had to ream  
the hole to 1/4 inch.  It should be possible to come up with a  
capacitor size that would give a 125 kHz. range, which I think would  
be ideal for 40 meters, but I haven't tried that yet.

Re: [Elecraft] Is NR effective on ssb?

Research by the hearing aid industry suggests that noise reduction 
reduces listener fatigue but does not increase speech intelligibility.

Re: [Elecraft] Roofing filter for CW

[Matt Zilmer]

Bill,

I have a very similar filter set (to Brett's as shown below),
including the 250 Hz 8-pole.  

I find the 1 KHz is best for casual CW and digital modes, and the 250
Hz filter is best for eliminating strong adjacent signals and in CW
pileups.  Would have to say that I'm on the 1 KHz filter 90% of the
time though.  The 250 gets put into service when it's contest time, or
the bands *really* open up (like lately).

You can put a lot of energy into a 250 Hz bandpass, so it's also
excellent for weak CW and some digital signals.  Because it's so
narrow, you may find tuning with the 250 to be hit-or-miss.  If you
tune with the 250 Hz filter, maybe try FINE resolution.  Also, with a
narrow filter like this one, you may want to boost the gain to 3 or 4
dB.

Remember that the roofing filter is only part of the equation.  The
DSP really provides the ultimate bandpass shaping, so you can still
get down to 50 Hz (I think...) in CW using the WIDTH or HIGH/LOW
controls.

[Elecraft] K3 / W2 utility conflict

[Mike Clarke]

Hi all,

Some months ago, I posted[1] about an issue I had with k3util not
functioning correctly on Linux if $HOME/Elecraft already existed,
but $HOME/Elecraft/K3_Firmware did not.

I've just bumped into this problem again, and lost quite a bit of
time before remembering the previous issue.

The problem is this:

w2util will create $HOME/Elecraft on first run, and use it to
store downloaded firmware.  If $HOME/Elecraft already exists, it
still works fine.

k3util will create $HOME/Elecraft/K3_Firmware to store downloaded
firmware.  However, it $HOME/Elecraft already exists, k3util will
silently fall back to storing downloaded files in the current
working directory.

Therefore, if, as I just did, you run w2util on a computer that
you've never used k3util on, and then you run k3util on that
system, it will confusingly download the files to unexpected
locations.

Would it be possible to change k3util so that it prompts the user
for permission and then creates the required directories?
Silently falling back to the current working directory should
certainly never happen.

As an added bonus, how about a command-line option to allow the
user to specify the download directory automatically?  Something
like 'k3util --download-dir="..."' would be very handy.

Re: [Elecraft] Roofing filter for CW

[Brett Howard]

I do mostly CW but every so often head up and do SSB for contests.  I
also wanted the ability to do FM on 2M.  So my choices are 13Khz,
2.8Khz, 1.5Khz, 1.0Khz, 250Hz.  I have that combination in both
receivers and I'm very happy with the way it works.  If I was 100% CW
I'd probably have gotten the 2.7Khz (5Pole), and then add the 1.0Khz
for CW tuning, and 250Hz (8 pole) for pileups.  I find that I often
sit around 600 to 800 as well and thus why the 1.0Khz filter works
great.  It gives you a nice space to run around in and get what you
want with the DSP while keeping the ADC's exposure fairly confined.
Then when you really want to get in close to someone and pull out a
weak one the 250Hz filter always brings a smile to the face.

Re: [Elecraft] K1 VFO Range Question

[Brett Howard]

I really like the ability to get up higher and also like the "fast
qsy" ability that the wider range gives you.  Some feel that its a bit
fiddly and you have to turn the knob a bit too finely but I honestly
kinda like the speed of the knob and I also like being able to pick up
WWV to verify my frequency counter and determine if I need to cal it
again.

Re: [Elecraft] Roofing filter for CW

[Bob - W0GI]

I agree that no wider then the 500Hz. If I had umlimited money, I would add a
1000Hz to my 250Hz as it would be nice for tuning, but then tuning with the
DSP set to 1000Hz it just fine.

Inrad should have another batch of 1500Hz filters made up next month, and
that is a nice filter for CW tuning, and usable on SSB.

I have been using the combo for over a year with no problems. I use the default 
settings and just connect the amp out, no ALC. Works great full QSK.

Re: [Elecraft] Roofing filter for CW

[Hector Padron]

500 or 400Hz 8 poles (xtals) must be your choice for the narrow roofer when you 
be on CW.If you are a contester,narrower BW will be even better like 250 Hz but 
always 8 poles,in my K3 I only use the 500Hz and with the DSP set at 200Hz its 
a brick,very selective RX.

As a prospective buyer of the K3, and a 100 percent CW op, I am wondering which 
of the roofing filters is the correct choice, assuming I am buying only one??  
I usually find that when operating weak sigs with my Pro 3, a bandwidth of 
about 600 to 800 hz is plenty adequate in normal QRM conditions.  With that is 
mind, am I better off with the 1000 or 500 HZ 8 pole filter???

Re: [Elecraft] Is NR effective on ssb?

[Hector Padron]

After hearing the three MP3 samples of noise reduction in that web page I can 
tell I was not impressed,actually my K3 can wipe out those noises better than 
that "LINGUA" product,I was expecting a better performance but I don't think I 
would spend over $200 US in that small box when I can do the same or even 
better with my K3 NR,there are sometimes that the same kind of noise I heard 
there,disapear completely after playing with the different NR setings,I am very 
pleased with the performance of my K3 NR,it really works !!

I agree. I use a predecessor of this product, it was sold as a kit once.  
I don't know if the algorithm has been improved in the meantime, but my 
box works really good. The depth of noise reduction is adjustable with a 
pot and it does not reduce the loudness of the signal but only the noise. 
At the highest NR setting voices start to sound "spacey". I normally use a 
medium setting for best S/N effect. 
The noise reduction is only noticeable wih weak noisy signals. There is 
nearly no effect on S9+20 signals without noise.
My box has one disadvantage, I don't know if this has been changed with 
the new product, there is only one channel, so the sub receiver has no NR.
You might need two of them. ($$)

Re: [Elecraft] P3

[Phil Hystad]

Years ago, back in the mid-1970s I worked on a signal processing project for 
the government.  We produced spectrograms which are used for the same purpose 
as waterfall displays.  We produced spectrograms on (then) very expensive 
RAMTEK color graphic displays and also printed on paper.  My role though was 
not the signal processing, I worked on the software for the display and device 
drivers for the special spectrogram printers.

[Elecraft] P3 sensitivity

On my K3 (with IF output mod) I measured a "transfer gain" (gain from
antenna input to IF output) of around -6 to -7 dB with preamp off and +4
to +5 dB with preamp on, depending on the band.

The noise figure of the P3 is a little hard to measure since there is no
access to its "IF" signal and there is no product detector/audio output,
but the design should be capable of around 7 dB NF.  Assuming the NF of
the K3 is 17 dB with preamp off and 10 dB with preamp on, you can crunch
the numbers and calculate that the NF of the K3/P3 combination should be
about 18.6 dB with preamp off and 10.7 dB with preamp on.  (Actually the
18.6 dB figure assumes that all K3 noise is introduced before the IF tap
point, which is probably too pessimistic an assumption.)

So the NF of the P3 display should be within a dB or so of the NF of the
K3 alone.  And of course band noise will totally swamp out receiver
noise in most situations anyway.

You should be able to see signals on the P3 that you can't hear.
(Unless you have VERY good ears!)

Re: [Elecraft] K3 in SSB

[Bob - W0GI]

While I got the K3 for CW and digital, and still like the Mark-V for
operating SSB, I find that the K3 is just as capable for SSB as the Mark-V,
and maybe more capable after I learn more about setting the NR. 

On SSB I find the Mark-V more convenient to operate, but it isn't really any
better in performance. More creature comfort then anything else.

Re: [Elecraft] K3 in SSB

[KD3TB]

Our VE2DXY team (zone 2) exclusively used K3 Radio's for the CQWW SSB
contest last year. Previously we had used Icom 756pro's and other Icom
radio's. Although not, scientific, and there are many factors which affect
propagation, we felt there was a significant difference in our ability to
hear and work weak stations.  We also felt that the filtration in the K3
gave us an edge in the crowded bands even over the 756pro with the IRC
roofing filter installed. If you can't hear them, you can't work them. One
of our operators who joined us this year had previously used an Icom 7800 in
the contest. He was so impressed with the performance of the K3 that he
stated he wanted to purchase one going forward. 

This weekend, I used the K3 in AFSK for the RTTY contest. I used the 500 Hz
roofing filter and was able to work numerous stations, picking out stations
in a very crowded band. Previously I had used my Icom 756pro.

Once again, this is not scientific and just my opinion.

Re: [Elecraft] K1 VFO Range Question

[Bob - W0GI]

You really don't need to change the crystal, unless you want to receive WWV @
10 mHZ. It would be easier to leave the crystal as it is, in case you go
back.

As for the filters, if you leave them alone nothing will change on the band
segments you currently use. On 40 meters, you may want to peak the filter a
little higher at maybe 7.070 mHz. Since you probably won't use the extended
range on the other bands, you can leave them be.

It is a bit touchy to tune, but then I like the ability to get to the old 40
novice band.

If you just do the VFO, it is easy to go back. If you like the change and
want WWV, you can do the crystal later.

Re: [Elecraft] P3

[Jack Smith]

The Z1B buffer amp PCB at 8 MHz has an input impedance dominated by 
4.7K to ground and about 2 pF shunt capacitance. The 200 ohm resistor is 
in series with the input and is not of significant concern in the input 
impedance relationship.

Even with a reasonable length of coaxial cable between a Z1 and the 
K3's IF output port, the Z1 has sufficiently high input impedance to 
not appreciably load the IF port, so there is another 5 or 6 dB  gain 
pickup over measuring the IF port level with a 50 ohm instrument such as 
a spectrum analyzer.

That isn't true. PSK31 was invented by G3PLX and there was a waterfall in
his reference implementation of the mode, psk31sbw.exe. The innovation of
Digipan was to allow you to click on a signal in the waterfall and receive
or reply to it anywhere in the audio passband, whereas the G3PLX software
required you to tune the signal in to a specific frequency, rather like
using the built-in decoder in the K3.

  CTL 3.10

(The version numbers are made up - I'm at work now.)  What I had hoped to do was
send a DS to retrieve the display state and get the 'DSP ...' string.  Then 2000
ms later, send a second DS to get the display at that point.

What happens, though, is that no matter how I adjust the timing, I can only get
the final 'CTL 3.10' display but nothing when I had hoped to retrieve the 'DSP
3.16'.  Or, I can get only the 'DSP 3.16' and not the CTL display.

Is it possible to do what I'm trying to do?  Or is the 2 s delay still part of a
single K2 display that can't be retrieved via two DS commands?

Thanks,
Mike ab3ap

Re: [Elecraft] K3 DSP board upgrades delayed

[Doug Turnbull]

Bob and co,
I ordered my DSP Upgrade board sometime before Christmas and expected it
within three weeks but it took more like seven weeks.   I have since
received the DSP Upgrade board installed it and returned mine within a week
but of course it will take another week to reach Aptos.   The original board
has an invoice value of around $380 so very few of us could afford to just
replace the board.   I believe Elecraft is offering a very good service in
this exchange and they of course rely on the return of the old boards to get
out the upgrades to others.  Of course my bit was well chomped on by the
time the board arrived and I suppose this is the way the P3 now appears to
me.   Good luck and patience.

 73 Doug EI2CN

~7 dB is correct when the IF out is driving a 50 Ohm load.  
Drive a high impedance load (e.g., the 200 Ohm input of Jack's 
amplifier) and the "loss" is 1 dB.  I believe Jack has a more 
complete explanation in the Z-1 amplifier manual.

[Elecraft] K1 VFO Range Question

[rhulett1]

I built my K1 awhile ago with a VFO range of 80 kHz, also a 4 band filter and 2 
band filter.  
With recent increase in QRM levels on 7030-7040+-, am considering expanding the 
range to 150 kHz.
This will allow me to work the old Novice segment on 40M.  Seems the  only 
change needed is the band crystal for 30M on the filter board and one capacitor 
on the RF board.  Noting the caution in the
manual about using wider range with the 4 band filter am wondering what other 
folk's experience
has been with the wider range.  I'd hate to foul up what has been a wonderful 
QRP rig.

Thanks and 73, Curt KB5JO

I'd like to see some specs for the P3 to know that it really has the
sensitivity to do this.  The IF OUT mod regains ~10 dB of the signal lost in
the original design but I believe that still leaves ~7 dB that may be lost,
according to Jack Smith's measurements:

Re: [Elecraft] K2 maiden flight

[lstavenhagen]

Ok, tnx gentlemen for the info. 

Well then I'm completely out of things to troubleshoot or find wrong. It's
100% as far as I can tell so I guess it's all buttoned up and time to just
go QRV.

I did order the NB module yesterday, tho, as the rig is basically unusable
at night now due to the line noise. I believe that's the last thing I really
need to add to the rig.

I really want to try portable now so may end up with a buddipole or
buddistick to try that next (a T1 tuner is also on the way along with the NB
module). And off to practice my sending as well

Tnx es 73,

Re: [Elecraft] K2 maiden flight

[Don Wilhelm]

LS,

Don't worry about the flash of power or speed.  Many K2s do that 
occasionally.  It has to do with the firmware loading down with many 
things to do at once.  It does not indicate any problem with the pots.

Re: [Elecraft] How to build an old KSB2 kit?

[Don Wilhelm]

Bob,

I would recommend ordering new crystals - and change the ones in the 
base K2 as well if they are the same vintage.
Then decide on the SSB filter bandwidth you want - 2.1, 2.4 or 2.6 kHz.  
If you want anything other than the 2.1 kHz bandwidth, then order the 
SSBCAPKT from Elecraft.
Build all except the filter capacitors from the manual you have, then if 
you ordered the SSBCAPKT, follow the instructions with that kit to place 
the proper capacitors.
If you do it as I described above, there should be no concern about the 
board level.  There has not been much changed on the KSB2 board since 
the beginning.  There were some value changes in the ALC section, and 
'way back when', D5 was added.  You have the new ALC values with the PSK 
kit, and if there is no D5 on that board, you might want to consider 
breaking the trace and adding it - you will have to work from the new 
schematic to do that, there are no instructions available.  If you are 
not capable of doing that, just forget about D5, it is not critical.

Don W3FPR

[Elecraft] Another webside where to see faster the P3 at Orlando hamfest

[Hector Padron]

You can see easier and faster the P3 video at Orlando hamfest at this italian 
DX website courtesy of Sylvano I2YSB,you won't be able to download it to your 
PC but the speed to see it is higher.

Spectrograms, such as "waterfalls," make use of your eye-brain system to help 
find signals that are below the noise level, especially when signals are 
drifting and don't allow temporal averaging methods.

You can see an example of its use (1971) here:

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19730010095_1973010095.pdf 

Fig 11-7 on page 130 (although poorly reproduced in the PDF scan) and the text 
on that page explains its use for discovering very, very weak and very, very DX 
signals.

In the amateur world, the first use of waterfalls was by Skip KH6TY in his 
Digipan program, I believe.  Without Digipan and the ease of "waterfall 
tuning," PSK31 probably would not have become as popular as it is today.  

With the addition of some special filtering, you can make a waterfall see even 
deeper into the noise when the signal is not drifting. The two figures here

http://homepage.mac.com/chen/w7ay/cocoaModem/UsersManual/mfskManual/mfskManual/dominoex.html#weak
 

show the same weak DominoEX signal with 18 FSK carriers.  The top figure is 
what the weak signal looks like in a simple waterfall, and the figure at the 
bottom, with the same input SNR, takes advantage of a signal that is not 
drifting, as explained in the accompanying text.  

In the digital world, you can't work them unless you can *see* them :-).

A good waterfall display will also show a CW signal that you can't hear, and 
can make "zero beating" a virtually instantaneous effort.  Or zero beating to a 
synchronous AM carrier, etc etc.

Re: [Elecraft] P3

[turnbull]

Eric,
When you write the manual for the P3 would you please include a good 
explanation of the use of waterfall displays.  I have one on my OII but do not 
fully understand its benefits.   

 A second point is that it will be interesting if the frequency display can 
be used to observe the width of signals.   The third point previously mentioned 
is that it would be nice to be able to monitor the transmit waveforms on SSB 
and CW.   Regardless, I am looking forward to my P3!  Thank you.
