Re: [Elecraft] KAT500 and KAT500 Utility Question

[Wes (N7WS)]

I don't believe that it has anything to do with whether or not a match can be 
reached.  Some SWRs are simply too difficult to measure accurately, even with an 
error-corrected network analyzer.  For near ideal reactances or very high or 
very low SWR, reflection measurements are inappropriate.  In other words, if the 
impedance is on or near the periphery of a Smith Chart (rho ~ 1) find another 
method.

Re: [Elecraft] MAB boards for the K2?

[Doug Shields]

Rueben,
 I brokered the last bunch of MAB boards.  All have been sold.  If there
is interest, we can make another run of boards.  I think I have a few parts
left over but we can come up with full kits if anyone is interested in
those.  If you are interested in boards or kits let me know.

Some of what you say is true, but has nothing to do with the problem.

ever use ladder line.

Feed point Z's:
1.9: 5.6-j1149
3.9: 78+j2
7.2: 2703+j2201

Your ladder line will transform these impedances to something else ... 
unless it happens to be a multiple of a half-wave at one of those 
frequencies.  Tell me how long it is and we can calculate what it looks 
like on the high side of your 4:1 transformer.  I don't recommend 
holding your breath that it will be good on all three bands though.


This weekend, I was curious as to how close (or far) the KAT500 could

The radiation resistance on 160 will be very low and the 4:1 transformer 
will divide it by 4, meaning just a tad above 1 ohm.  It is also very 
reactive.


If you really want to use it on 160, try shorting the ladder line at the 
feed end, remove the transformer, and connect the shorted end to the 
coax through a variable cap.  Run 1 or 2 wires on the ground from the 
coax shield and see if you can feed it as a Marconi-T.


If your ladder line is 60 ft long, feed Z at the shorted end of the 
ladder line will be about 110+j1400 and an Xc of 1400 ohms will probably 
work fine for the KAT500.


So, as I expected, the tuning never closed in on a descent SWR, the
best I saw on one test only was SWR about 49:1 as reported by the

SWR meters, which usually measure VSWR are fairly unreliable at high 
values of mismatch.

[Elecraft] K2 Question: Is the DSP Board a Worthwhile upgrade?

[David Inger]

A friend has a fairly recent K2 with the KAF2 audio filter option.  He asked
me to remove the KAF2, build the KDSP2 board and install it in his K2.  This
got me to thinking:  I also have a K2 wiht the KAF2 installed.  My friend
works mainly SSB; I work main CW and digital modes.  Is the DSP board a
significant improvement over the bare K2 or even with the KAF2 installed
(which seems to be tailored for CW reception)?  In general, radios  that I
have owned with AF DSP have been pretty much a disappointment.  So is the
KDSP2 a worthwhile and cost-effective upgrade?

Hi Michael,

You can use the "AK;" command to get the KXAT3's relay states.

The response format is

   AKaabbcc;

where:

aa = inductance IO bitmap in ASCII hex
bb = capacitance bitmap in ASCII hex
cc = misc relays bitmap in ASCII hex

The  and  bitmaps can be equated to L and C values by looking at the 
KXAT3 schematic. For example, a value of "01" would represent the smallest L or 
C value in the network.
 
At present only bit 0 of byte cc is defined:

00 = capacitors on antenna side
01 = capacitors on antenna side

If the ATU is not installed, or is in one of the Lx/Cx test settings, 
“AK00;” is returned.

In BYP mode, on some bands L and C are set to fixed non-zero values in order to 
cancel the ATU's own reactance when working into a 50-ohm load.

In AUTO mode, the working auto-tuned values are shown.

73,
Wayne

Re: [Elecraft] K2 Question: Is the DSP Board a Worthwhile upgrade?

[Don Wilhelm]

David,

The KAF2 is mainly for CW use.  It provides a great peaking filter at 
the frequency that you have set it to (presumably your sidetone pitch).
It also has a low pass filter that is in-circuit at all times.  That can 
reduce band noise hiss for all modes.


The KDSP2 also provides filtering for CW, SSB and data modes.  If you 
are bothered by signals nearby in frequency, the straight-sided filters 
of the KDSP2 will be an advantage.


The KDSP2 also provides noise reduction algorithms, although turning on 
NR in any transceiver can introduce distortion for voice signals.  How 
bad that is will be determined by the aggressiveness of the algorithms.  
The KDSP2 does allow a wide range of settings, and you may have to 
experiment with those setting if the defaults do not satisfactorily 
handle your particular noise situation.


So, not directly answering your question, the KDSP2 can provide 
filtering as good as the KAF2 (even better), but if the operator is CW 
oriented, the additional cost of the KDSP2 option may not provide the 
improvement expected - for SSB operation, there is no choice, the KAF2 
is not useful on SSB (other than the Low Pass Filter) and the KDSP2 is 
the only real choice between the two.

Re: [Elecraft] K2 Question: Is the DSP Board a Worthwhile upgrade?

[Matt Maguire]

When I built my K2 a year and a half ago, I also had to decide between bare K2 
vs KAF2 vs KDSP2, and went through the archives. In the end I went with the 
KDSP2, but some of the points I considered along the way:

Bare K2:
- built-in IF filters do work very well, but I read some reports that strong 
stations nearby can produce some « blow-by », and that either the KAF2 or KDSP2 
can help clean it up.
- At some point, Elecraft may cease production of the K2, and if I leave my K2 
bare, I may not get the chance to upgrade it later.

KAF2:
- cheap, very easy to use
- for CW, reports seem to indicate it performs about the same as the KDSP2
- has a nice LPF stage that cuts down background hiss, seems to be better than 
the KDSP2 in this regard. Some people have added a KAF2-style LPF to their 
KDSP2 with good results.

KDSP2:
- much more configurable than KAF2
- has noise reduction feature, I thought this might come in handy if I have the 
K2 as a second radio, and have it sitting on my club’s SSB calling frequency. 
It does keep the radio very quiet, almost like a voice squelch.
- also has automatic notch filter, in case I need it
- can go very narrow. I had good experiences with the DSP filtering in my KX3, 
which was really effective in digging out some very weak sigs on our QRP net 
(although so far I have mainly used the K2 for rag chewing, haven’t really done 
any side-by-side comparisons with KX3)
- Code for the DSP is open source, so might be fun to play with. However, I 
think the development kits are now out of production, and I think maybe the 
chip in my KDSP2 was not in a socket, but soldered directly to the board 
(someone correct me if I am wrong). So, there are some barriers to playing with 
the DSP code, and if I wanted to experiment in DSP techniques, a much easier 
way would probably be to use a generic PC with sound card and GNUradio or 
similar development environment.
- KDSP2 chews a lot more power than KAF2, which may be an issue if you like to 
run off batteries. You can disable the KDSP2 through the menu, which 
significantly reduces but doesn’t eliminate the additional power draw. If you 
power-cycle the K2, the disable setting of the KDSP2 is forgotten, and the 
KDSP2 will become active again.
- the KDSP2 is a lot more complicated to use than KAF2. This means you have 
more flexibility, and some people like having lots of settings to play with, so 
it can be a plus. But it can also be a minus as it can be hard to remember how 
to change some of the less commonly adjusted settings. Having said that, the 
defaults on the KDSP2 are usually fine. 

So, is the KDSP2 a worthwhile upgrade? For your SSB friend, I would say yes. 
For a primarily CW operator like yourself who already has a KAF2, it might be 
harder to justify. Is the upgrade cost-effective? Well, the KDSP2 is 
significantly more expensive than the KAF2, and it is a personal choice whether 
the extra value/fun brought by the KDSP2’s additional features warrants the 
additional cost. After all, it is a hobby :-)

[Elecraft] Bias and Dynamic Mics

[Jim Brown]

On Wed,11/4/2015 5:43 AM, Charlie T, K3ICH wrote:

If you ever wondered why a bias voltage can cause
distortion in a dynamic microphone element, just
consider what happens when you connect a DC source
to a speaker.  The voice coil move in one
direction depending on the polarity.  Now think of
a dynamic mic element doing the same thing.


This is one of those ideas that, while having a solid theoretical basis, 
doesn't hold up once you plug numbers into the problem. That's because 
the bias voltage is typically provided from a rather high impedance 
source, so the bias current is too low and the sound pressure level is 
too low to drive the diaphragm anywhere near its limits.


The simple fact is that it's virtually impossible to overload a dynamic 
mic. One major mic manufacturer advertised that their dynamic mics could 
reproduce a gunshot without distortion. It wasn't a lie -- almost any 
pro dynamic mic can do that. When you hear distortion from a dynamic 
mic, it's the mic producing enough output to overload the mic preamp, 
and the solution is to either reduce the preamp gain or add a pad 
(passive attenuator). Controls to do both are built into the mixers used 
for live sound, broadcast, and recording.

Re: [Elecraft] KAT500 and KAT500 Utility Question

[Wes (N7WS)]

Guys, read what he wrote, not what you think he wrote.

He had a question about the operation of the metering in the KAT500, he wasn't 
looking for advice on antenna design or on the use of ladder line.


If he wants that he can read my paper here: 
http://k6mhe.com/n7ws/Ladder_Line.pdf

it with other bands.


Feed point Z's:
1.9: 5.6-j1149
3.9: 78+j2
7.2: 2703+j2201

Your ladder line will transform these impedances to something else ... unless 
it happens to be a multiple of a half-wave at one of those frequencies.  Tell 
me how long it is and we can calculate what it looks like on the high side of 
your 4:1 transformer.  I don't recommend holding your breath that it will be 
good on all three bands though.


This weekend, I was curious as to how close (or far) the KAT500 could
bring the antenna in for the 160 meter band.  I knew that it would
not work though I was wondering how bad it would be.


The radiation resistance on 160 will be very low and the 4:1 transformer will 
divide it by 4, meaning just a tad above 1 ohm. It is also very reactive.


If you really want to use it on 160, try shorting the ladder line at the feed 
end, remove the transformer, and connect the shorted end to the coax through a 
variable cap.  Run 1 or 2 wires on the ground from the coax shield and see if 
you can feed it as a Marconi-T.


If your ladder line is 60 ft long, feed Z at the shorted end of the ladder 
line will be about 110+j1400 and an Xc of 1400 ohms will probably work fine 
for the KAT500.


So, as I expected, the tuning never closed in on a descent SWR, the
best I saw on one test only was SWR about 49:1 as reported by the
KAT500 utility.  But, the BYPASS SWR reported was about 11:1.


SWR meters, which usually measure VSWR are fairly unreliable at high values of 
mismatch.

Re: [Elecraft] KX3 auto tuner solution available after tune? [TYPO FIXED]

There was a typo in the byte  information -- now fixed.

Hi Michael,

You can use the "AK;" command to get the KXAT3's relay states.

The response format is

  AKaabbcc;

where:

aa = inductance IO bitmap in ASCII hex
bb = capacitance bitmap in ASCII hex
cc = misc relays bitmap in ASCII hex

The  and  bitmaps can be equated to L and C values by looking at the 
KXAT3 schematic. For example, a value of "01" would represent the smallest L or 
C value in the network.

At present only bit 0 of byte  is defined:

00 = capacitors on the antenna side
01 = capacitors on the transmit side

If the ATU is not installed, or is in one of the Lx/Cx test settings, 
“AK00;” is returned.

In BYP mode, on some bands L and C are set to fixed non-zero values in order to 
cancel the ATU's own reactance when working into a 50-ohm load.

In AUTO mode, the working auto-tuned values are shown.

Re: [Elecraft] K2 Question: Is the DSP Board a Worthwhile upgrade?

[James Bennett]

David, 

My K2 is long gone, but I can tell you about my experience with the DSP module. 
I operate mainly CW, and added the DSP option after having the K2 for over a 
year. For me, it was a mistake. The radio didn't sound as good as it did before 
adding it. I wound up taking it out and selling the board. 

Maybe it was me, maybe I didn't have something set right, but whatever it was, 
if I owned a K2 today there is no way I'd put that option in it. Just my two 
centavos...

Thanks, you are exactly right.  My curiosity is about what the KAT500 was doing 
and the value of the BYPASS SWR versus the values I saw of the Tuned (or, not 
tuned) SWR.  

Dick’s answer was right on and satisfied all my curiosity needs.

Though thanks to all that took the time to write something down and Wes, I will

Re: [Elecraft] Bias and Dynamic Mics

[Bob McGraw - K4TAX]

While I agree with Jim, K9YC on this.  Some dynamic mikes I've 
encountered do use a transformer to get the voltage level from the very 
low impedance Z element to a respectable output value.  Running a bit of 
DC through the transformer on the secondary side could tend to cause 
some DC saturation.   And transformers which are not designed to handle 
DC can behave a bit odd under this condition. Other dynamic mikes I've 
encountered provide an internal DC blocking capacitor to prevent this 
issue, although that in itself has its issues.


Yes, with any dynamic mike being used, set the bias to the off 
position...just to be safe.And don't worry about overloading a 
dynamic mike, but do be concerned with the preamp or first analog stage 
being driven into distortion.

[Elecraft] Microphone Setup

[James F. Boehner, MD via Elecraft]

Don, 

Thanks to you, Richard, Gene, Charlie, Bob and Mitch for your constructive
and educational responses on this topic.

Don, I am happy to say that the settings you mention below were the ones
that I settled on after some experimentation prior to my post.  I appreciate
the validation and the background on the reasons why those settings are the
desired ones.

Not all information is in the manual, certainly not specifics.  The
collective experience on this list is greatly appreciated, especially from
those of us that are new to the Elecraft line.

Thanks again!

Subject: Re: [Elecraft] Microphone Setup

Dr. Jim,

There is no FAQ that I am aware of.
Actually the information is pretty basic.  Microphone elements come in two
basic types - Electret and Dynamic.
The Electret types need a DC bias applied to the AF line.
The Dynamic elements should *not* have bias applied or they will be
distorted.

The other thing that often causes confusion is the mic plug pinout. The mic
plug wiring must match the pin arrangement used in the transceiver, and that
information is shown in the transceiver manual.  In the case of the Elecraft
K3 and K3S, the 8 pin mic pinout differs only from that used by Kenwood in
that the use of pins 5 and 6 are reversed.  Since most Kenwood unamplified
dynamic microphones do not use pins 5 and 6, most all Kenwood dynamic
microphones will work directly with the K3 and K3S.

Heil microphones normally use a 4 pin XLR as a generalized connector
*and* use an adapter or special cable to change that XLR connection to that
required for the transceiver.  The adapter to be used with the K3 and K3S is
the one for the Kenwood (which has a red band).

Heil microphones come in both the dynamic and the electret types, although
most are dynamic.  If the microphone is designated with a "-iC"

A lot of information on microphones and transceiver connections can be found
at http://homepage.ntlworld.com/rg4wpw/date.html.  G4WPW has done an
excellent job of collecting information about microphones, mic pinouts and
even schematics.

In your particular case with the Heil PR-781, use the Kenwood cable (Heil
CC-1XLR-K) with that microphone and make certain the bias is turned off.
I believe that microphone has a rather low output, so you may have to use
the high range for the mic gain.
So - the K3(S) MIC SEL menu should be set to "FP H".
Set the mic gain as described in the K3 manual - first set compression to
zero, then adjust the MIC GAIN until you see 5 to 7 bars illuminated on the
ALC meter (that can be done in TX TEST so no RF is produced).  
Then bring the compression up to your tastes, usually in the 3 to 6 dB
range.

Re: [Elecraft] K2 Question: Is the DSP Board a Worthwhile upgrade?

[Sverre Holm (LA3ZA)]

I would not have upgraded to the KDSP2. Not for the performance, because
although I'm mainly a CW operator, I could probably benefit from it.

My main objection to the KDSP2 is user interface. The K2 was not designed
for the KDSP2 in the first place as can be seen in how complicated it is to
set up and operate compared to the other K2 modules. Given the few buttons
of the K2, the user interface for the KDSP2 is probably as good as it can
be, but still it is so much harder to use than the other options. The
otherwise well thought-out user interface of the K2 is made unncessary
complicated by the KDSP2 with all its features.

This can be read indirectly from the history of Elecraft here:
http://udel.edu/~mm/ham/elecraft/history/

Quote: 
"A major milestone in our history was the KDSP2 option for the K2. Lyle
Johnson, KK7P, became known to us *after* he had mostly completed this
highly versatile DSP unit. He reverse-engineered the auxBus protocol and
made the KDSP2 behave as if it were a KAF2, which plugged into the same
spot. He showed it to us, and we immediately adopted both the product and
Lyle himself."

Definitely true re user interface.  But if you get 
it set up in a way that works well for you, then 
not much need to tweak.


I don't often change settings in my K3 DSP either.

Exactly right, Bob. And Don Wilhelm reminded me that some mics used with 
a K2 didn't like bias. That can, of course, depend strongly on the value

It all depends upon whether you think of electrons or the spaces (holes)
electrons fill as they migrate.  

Picture a straight row of coins on a tabletop. Mark the location for each
coin. Now remove a coin at one end. That represents your power source
pulling an electron away from an atom at the positive end of the power
supply. Start shuffling the coins from one side to the other beginning at
the end with the missing coin to fill it's gap, carefully moving one coin at
a time to the marks keeping the gap open. Note that the coins (electrons)
are moving in one direction as electrons move from negative to positive
while the gap (hole) moves in the opposite direction from positive to
negative.

Re: [Elecraft] P3 - Waterfall Marker?

Hi Steve,

I agree that a dot or small vertical line at the bottom of the screen
would work great for this purpose.

The bottom white 'frame' already has small vertical 'tic' marks on it. I
think adding a small tic or dot just beneath that bottom frame would do
the trick. That way, the active part of the screen isn't being painted.

[Elecraft] OT: geomagnetic storm effects on bands?

[Al Gulseth]

Greetings Elecrafters,

I have an older Sangean portable next to the bed that I sometimes listen to 
while I'm settling in for the evening. Frequently I'll tune in W1AW for a 
quick rough propagation indicator. Last evening 40M, which usually has a 
strong signal in the 9-10 PM Central timeframe, was much weaker than usual. 
80 was also down, so I went to 20 expecting a weak signal at best as the band 
is usually shutting down by that long after sunset. I was surprised to hear a 
stronger signal there than on 40, and I could also hear W1AW on 17 and 15, 
which are usually dead by then this time of year. Is this possibly due to the 
current geomagnetic storm? (I'm still learning when it comes to 
solar/geomagnetic events and propagation.)

TNX/73, Al

Re: [Elecraft] Microphone Setup

[Bob McGraw - K4TAX]

Jim:

I use the PR -781 on my K3S with excellent results.

From the MENU scroll to  MIC SEL - choose FP.H meaning front panel 
high.   {See page 55 of the K3S manual.}


From the MENU select TX EQ  {See page 56 of the K3S manual.}
set frequencies as follows
#1  50 Hz -16
#2  100 Hz-8
#3  200 Hz 0
#4  400 Hz 0
#5  800 Hz 0
#6  1600 Hz   0
#7  2400 Hz   +3
#8  3200 Hz   +6

Scroll to VOX gain and set the value to 020
Scroll to ANTIVOX and set the value to 010
Exit MENU to save.

Go to the CONFIG menu and scroll to  TX ESSB   {See page 66 in the K3S 
manual for details.}

Set this value to ON and  3.0
Exit menu to save.

From the front panel:
Set the MIC gain at about 40.  This gets about 4 to 5 bars on the ALC meter.
Set the COMP at about 15.  This gets about 3 to 4 bars on the CMP meter.

Operate with a mike-to-mouth distance of about 1 fist or about 4" to 
5".  If you get too close you will find the proximity effect will bring 
the bottom end up a noticeable amount.


Get ready for "great audio" reports!

Re: [Elecraft] Microphone Setup

[Don Wilhelm]

Dr. Jim,

There is no FAQ that I am aware of.
Actually the information is pretty basic.  Microphone elements come in 
two basic types - Electret and Dynamic.

The Electret types need a DC bias applied to the AF line.
The Dynamic elements should *not* have bias applied or they will be 
distorted.


The other thing that often causes confusion is the mic plug pinout. The 
mic plug wiring must match the pin arrangement used in the transceiver, 
and that information is shown in the transceiver manual.  In the case of 
the Elecraft K3 and K3S, the 8 pin mic pinout differs only from that 
used by Kenwood in that the use of pins 5 and 6 are reversed.  Since 
most Kenwood unamplified dynamic microphones do not use pins 5 and 6, 
most all Kenwood dynamic microphones will work directly with the K3 and K3S.


Heil microphones normally use a 4 pin XLR as a generalized connector 
*and* use an adapter or special cable to change that XLR connection to 
that required for the transceiver.  The adapter to be used with the K3 
and K3S is the one for the Kenwood (which has a red band).


Heil microphones come in both the dynamic and the electret types, 
although most are dynamic.  If the microphone is designated with a "-iC" 
or "-K2" it is an electret type.


A lot of information on microphones and transceiver connections can be 
found at http://homepage.ntlworld.com/rg4wpw/date.html.  G4WPW has done 
an excellent job of collecting information about microphones, mic 
pinouts and even schematics.


In your particular case with the Heil PR-781, use the Kenwood cable 
(Heil CC-1XLR-K) with that microphone and make certain the bias is 
turned off.
I believe that microphone has a rather low output, so you may have to

So - the K3(S) MIC SEL menu should be set to "FP H".

on the ALC meter (that can be done in TX TEST so no RF is produced).  
Then bring the compression up to your tastes, usually in the 3 to 6 dB 
range.

Re: [Elecraft] Microphone Setup

[Charlie T, K3ICH]

If you ever wondered why a bias voltage can cause
distortion in a dynamic microphone element, just
consider what happens when you connect a DC source
to a speaker.  The voice coil move in one
direction depending on the polarity.  Now think of
a dynamic mic element doing the same thing.  After
all, electrically, the element and speaker are
essentially the same.   The DC bias causes the mic
element's static condition to be physically moved
from its normal resting position, so the output
waveform will not be an accurate electrical
representation of the audio wavefront arriving at
the element.

73, Charlie k3ICH

Re: [Elecraft] K3/XV144 vs. KX3/XV144

[David Anderson]

For contesting in Europe ( I stress Europe because it is quite different to 
other areas of the world)  on 144 MHz you generally need very good strong 
signal handling and good selectivity as there are many stations running several 
hundred kW ERP often within line of sight of you. Imagine a mountaintop station 
with 16 yagis stacked often arranged to cover 360 degrees and running 3kW PEP 
output as some are permitted to do. Most normal transceivers even with fairly 
good transverters will fall apart under those circumstances. I have encountered 
receive systems that couldn't handle a line of sight station that was running 
100 watts and a single antenna without overloading.

You don't say how serious you are in 144 MHz contesting, and whether you 
already own a K3 or a KX3 and whether you already have the XV144 transverter, 
so it is difficult to know what your question is and give you an answer.

The K3 would certainly be the better contest radio, though of course more 
expensive once you load it is with filters. The nice thing is you can add just 
the options you require, if you don't need HF and 100 watts etc. 

However there are better transverters available for contesting on 144 MHz than 
the XV144.  There is the very expensive Kuhne TR 144 H , and the M+E ME2T Pro 
from HA1YA. The very best is needed for serious contest use.

If you want to build something there is the Javornik. Now we have the G4DDK 
Anglian transverter kit available which is also good by all accounts. GM3SEK 
has recently built an Anglian transverter and PA -inside-  his K3/10. The 
Anglian LO can be injection locked to 10 MHz too.

HA1YA also makes banks of IF switched xtal filters that go between the 
transceiver and the transverter at the IF to further improve strong signal 
handling when you have close strong signals in contests.

I live on the extremity of Europe and have only a few local strong signals to 
contend with, so rarely encounter huge problems with receiver overload, more 
commonly it is the poor quality of transmitted signals that causes problems ( 
IMD from over driven amplifiers and transmitted wideband phase noise from 
poorly designed systems). So I am happy with my KX3 with an ME2T Pro 
transverter at 14 MHz IF. However if I lived in Central Europe I would probably 
need something a little better and would certainly consider the K3S.

Having the PX3 panadaptor is also nice for finding stations (search and pounce) 
on the band, it also shows very graphically the difference between a good 
narrow SSB signal and one that is being over driven and splattering.

due to the current geomagnetic storm? (I'm still learning when it comes to
solar/geomagnetic events and propagation.)

[Elecraft] P3 - Waterfall Marker?

[Steve Ellington]

Am I doing something wrong or is this just how it works?

I have the P3's waterfall marker turned on. The "marker" slowly crawls down
the screen toward the bottom. Moving the Select knob drags the top of the
marker and the rest slowly follows drawing a snake. Cute but...huh?

Question: What good is this? The reason I would want the marker is to
quickly set it on a signal that has already progressed down the screen. I
can't because basically there's no marker. If I just wait for it, desired
signal is gone.

Why can't the marker in the waterfall just be an extension of the one in
the spectrum so you can use it? Is there some technical reason?

I'm used to using software for this and none of them work like this.

Am I missing a setting somewhere? I've looked hard.


Thanks for listening;

Steve N4LQ

Re: [Elecraft] P3 - Waterfall Marker?

[Paul Saffren N6HZ]

Hi Steve, 

That's how it works.  If you don't want the signal to roll off the bottom of
the screen, use Freeze to stop the screen from updating or turn averaging on
to slow the screen updates and provide more history.  

Kind regards, 

Paul

Re: [Elecraft] 10 mHZ external reference VS the K3S's optional KTCXO3-1

[Edward R Cole]

Thanks, Ron, that is a better description of the EXREF function.

I left out the page number where the TCXO specs are given (in my 2010 
K3 manual) - page 8

It lists TCXO3-1 as 1ppm but I think it was commonly found to do 0.5ppm.

That matches my measurements at 28-MHz of 14-Hz error.  MY actual 
EXREF measurements showed better than 2-Hz accuracy which implies 
better than 0.1ppm.  It was something like 3-Hz at 50-MHz.

The K3EXREF option locks the K3's reference oscillator frequency to an

oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not
phase lock the K3's reference

Thanks for the specific and detailed hints, Don (and thanks also to Matt and
Bob for helpful e-mails).  I decided to defer handling L33 and the two BFO
crystals.  I went ahead and reflowed the soldering for the other components. 
This has fixed the immediate problem: the center frequencies moved "up" and
was I able to easily align all the filters.  Hopefully, this will be a
permanent fix and there will be no further significant BFO drift.  If I
continue to see drift, then I'll go ahead deal with L33 (whose solder joints
all looked fine to me yesterday) and reflow the BFO crystals' soldered
leads.

Thanks again!

Re: [Elecraft] P3 - Waterfall Marker?

[Steve Ellington]

Paul et al
"Freeze" locks up everything including the marker so how does that help?

When searching for signals we might see one on the waterfall that is half
way down the screen. We want to mark, click or do something to get us
exactly on frequency so we can either wait for the signal to return or try
calling QRZ however there doesn't seem to be a way to get on frequency
other than a rough guess.

At first when you mentioned "freeze" I was excited but now I find that
using freeze makes the situation even worse since nothing responds. I'm
just looking at a locked up system!

The marker needs to be independent of the displayed materialLike a
mouse on virtually any other SDR software.
Is that something Elecraft can do or is it impossible with this hardware
configuration?

Thanks

Re: [Elecraft] P3 - Waterfall Marker?

[Al Lorona]

I think what Steve is asking for is a dot (non-line) marker at the *bottom* of 
the waterfall and that doesn't have persistence (doesn't "leave a trail"), so 
that he can line it up with a scrolling signal and then QSY to it before it 
disappears off the bottom of the screen. It's actually not too bad an idea, 
considering that signals are always heading to the bottom of the waterfall, but 
currently the marker's latest position is at the top of the waterfall.

Re: [Elecraft] P3 - Waterfall Marker?

[Steve Ellington]

I always used fixed mode. Nope doesn't help.
There needs to be a marker at least at the bottom of the waterfall so you
can mark the signal before it disappears and shift frequency to it.

Re: [Elecraft] OT: geomagnetic storm effects on bands?

 I was surprised to hear a
stronger signal there than on 40, and I could also hear W1AW on 17 and 15,
which are usually dead by then this time of year. Is this possibly due to the
current geomagnetic storm? (I'm still learning when it comes to
solar/geomagnetic events and propagation.)


Yes, it is quite possible. Geomagnetic storms can have interesting effects 
on the ionosphere and on radio wave propagation. Some years back there was a 
storm that pretty much killed all the ham bands on HF. I tuned around the 
bands and heard almost no activity. I eventually ran across two hams talking 
each other. Both of them had very good signals when I could hear so little 
activity. One person was in VK land (about the opposite side of the world 
for me). I forget where the other one was located.
