Re: [Elecraft] FSK on K3 using Winkey 3.0

Well, I meant 3.1.  The newest version.  Could you explain the connections
you used?  Pin 1 for fsk. Pin 4 for ptt.  Pin 5 for ground.  Another
components?

Re: [Elecraft] Voltage drop in DX Power to K3

[Leroy Buller]

40 inches of power cable.  In my experiences,  that could be an issue
depending on the gauge of the wire.  I used a long cable 12 gauge and had
issues.  Went to 24 inches number 10 gauge and voltage drop significantly
improved.  The resustace does not have to be large to cause a voltage  drop

Re: [Elecraft] K3S poor CW keying further investigation

[Leroy Buller]

Chuck, I am late to this discussion so I might be saying things that
already been said.  I found the same issue.  Voltage down to 11.5 volts on
any ps I used.  So, I found the issue was power pole connectors that were
to light.  Look for power pole connectors that handle 30 amps or so.  Power
poles come in different amperage with the same shell.  Don't get fooled
with that.  I did.

Then I limited the cable to 24 inches.  #10 wire and higher current power
poles.  Voltage dropped fro. 13.8 to 13.1 at 100 watts .

Somebody said that DC systems act significantly to resistance.   Lower the
resistance to the smallest number is what I tried to do.

Some ps have funky connectors o. The back, and might have to jigger those
to bolts and nuts.  I opted to use sleeves crimped on the end of the wire,
soldered, and then stuffed in the connector.   The set screws were replace
with machine bolts and tighten but you cannot over tighten because the
threads might strip.

[Elecraft] Clarification on Repair Process

[Leroy Buller]

My beloved K3 is in Watsonville for repair.  Now, I can wait, but just
curious as to how Elecraft will be dealing with repairs in light of the
folderol going on in our country.  Don't  get me wrong, I want everyone
health, wealthy and on CW...but curious how repairs are being handled.

Be safe.  Wash your hands.  Practice social distancing.  Take vitamins. Be
aware of your Toilet Paper levels.  Make sure your blinker fluid is topped
off.

Does Elecraft still have a support department or have they all move to K4
side?  I emailed the several days ago and no response .  They have always
been very prompt before or is the frenzied activity to get the K4 out

[Elecraft] High Current only on 20 Meters

[Leroy Buller]

I have a K3 that seems to have a problem.  I am getting HI CURRENT warning
only on 20 meters.  The antenna is matched.  80, 40 and 15 do not have the
issue.  The current meter on the power supply does show quite a bit of
current (20+ amps) on 20 meters but when I reduce power it stops giving me
the issue on 20 meters.  When I reduce power on 20 meters, the high current
goes away around 65 watts.

Anyone have an idea what is going on?  I do appreciated the help

[Elecraft] K4 Remote Information

[Leroy Buller]

As this old dog is learning about SDR, Remote Control and such I have a
simple question about "remote control of the K4."

I understand the K4 has a Linux computer in it that acts like a "server"
while controlling other aspects of the radio.  Now, in my experience, when
you had a server you need client softwareEXCEPT...if it is a web server
or an HTML server.  Soo

Does one connect to the K4 through a web server using Chrome, Firefox, or
Edge(?) to the rig or is there special software for the client?

Yea, I know...dumb questions.  But I am seeking clarity.

Re: [Elecraft] THE FUTURE OF OUR HOBBY

This is a concern of mine for Elecraft.  A low cost entry rig with 100

issue but maybe the old man rich market is big enough for all players.

[Elecraft] K4 Beta Testers

[Leroy Buller]

I assume the K4 is being beta tested by a group of  hand picked ops.  Is
that tfue?  I know they are sworn to secrecy but will there be any
discussion later on as to their observations of the various configurations
of the K4?

Reading the material is fine, but there is nothing better than direct
testimony from a user.  This is NOT a political statement.

[Elecraft] Comparison information

[Leroy Buller]

How does the basic K4 compare to the K3 when it comes to receiver specs?
Is the K4 SDR just as good as the superhetrodyne K3 or do you have to
upgrade to the superdooper K4?

Re: [Elecraft] Silent power supply for a K3s

[Leroy Buller]

This is an issue that I have also, but have chosen to ignore.  I have the
samlex, astron ss30 and a rm30.   The Quiet one is the rm 30.  You might
try to tighten the bolts on the transformer.  That helped mine, but no fan.

One issue is keeping the power cord short to keep from getting a voltage
drop.  You also have to use the right gauge of wire and 45 amp power pole
connectors.   So, the power supply has to sit close to the rig.   I have a
cord of 24 inches.  I have very little voltage drop and the K3 runs better
at 13.7 than 11.8v.

So, I have learned to ignore the fans on ft8, and I wear headphones for the
other modes.

Your mileage may vary, but if it has a fan you will get noise.  The AL 82
also is noisy but that's life.

[Elecraft] K4 and Linux Infrastructure

[Leroy Buller]

So, K4 and the internal Linux system.  What is it doing for the radio,
processor type, clock speed  ram, any ssd,  and version.  I am assuming or
guessing it is a PI of some sort or tigally designed by Elecraft?

Will anyone know?

[Elecraft] K4, Spouse, Retirement, Burning Fascination

[Leroy Buller]

Ok, I told myself yesterday when the K4 leaked in a deluge of emails, that
I was not going to get excited.   After all, I am a K3 owner serial 443.
This radio has been far beyond...great.  i can crank out cw QSOs with the
very basic K3.  The Elecraft experience has been superb and superlative.  I
loved my K2 too.  But, no way i could get a K4 because of the money
involved.

You see, i do not see rigs as investments.  I see them like having a
classic car.  I just want it.  But alas, i am retired.  Money is not tight,
just earmarked for certain things.  K4 is not one.

Now, i am flummoxed with a burning facination as to how i can obtain one of
these K4 Dream Machines.

I had to plant the seed of buying one with my Spouse and she wanted to see
how it looked.  I showed her the picture and said, "lots of buttons."  

Now, i see a glimmer of hope.

Long live The Wizards of Elecraft.

All Hail Prince Erik and Prince Wayne.

Re: [Elecraft] Intermittent loss of power output K3

Look at the two diodes in the SWR/watt meter circuit.  These two diode are

Re: [Elecraft] Urban stealth HF: Inside-the-backpack loop antenna?

When I was in College at Kansas State, I had a random length long wire out
the window and up into some trees from the basement apartment.   I used a

[Elecraft] K3 Standard internal Noise

[Leroy Buller]

I am trying to trace down a noise on 40 meters, but it seems to follow the
VFO.  On the P3, the noise is a gradual jump that is 6 khz wide.  After the
vfo is not used for a while, the noise disappears.   Anyone have a
direction to travel?  Only on 40 mtrs it seems.

Re: [Elecraft] I am flummoxed about my antenna

[Leroy Buller]

I think the counterpoise is wonky as many of you have stated..  I have
tested the antenna at the feed point at it is the same that I see in the
shack.  There is no resonance with this antenna.  Yes, it is cut long too.
When I did have it working it was 1.3 to 1 at 1835..  It is very wet and
rainy here and I think the counterpoise is a mess.  I have not done
maintenance on it this year since I was in the hospital in July and
recovering the last four months  Yes, it was that way.  So, next week, I am
going to put up two elevated radials about 7 feet high and then take off
the radials on the ground...or at least try to clean them up.  But, the
rain, wet and cold of Kansas has damped my enthusiasm for fixing it this
weekend.,  RATS!  I like the 160 contest.   But it does seem the actual
antenna is OK.  The end of the 130 feet has a big insulator on it and it is
about 6 foot from a tree limb.  So, it is not touching the tree.

Since I am retirednext week will be sufficient.

[Elecraft] I am flummoxed about my antenna

[Leroy Buller]

There
I tried to get on 160 with my Inverted L last night.  60 feet up and the
rest over to a tree, 130 feet total.  About 20 random length radials in the
yard.  The best I can do with a city lot.  This antenna worked last year
very well, but now I get this

12/1/2018 10:46:08 AM NOTES:

Frequency SWR
- ---
00180 1.3
00181 1.4
00182 1.4
00183 1.4
00184 1.4
00185 1.5
00186 1.6
00187 1.6
00188 1.5
00189 1.5
00190 1.6
00191 1.6

00196 1.6
00197 1.7
00198 1.8
00199 2.0
00200 2.1

There seems to be NO resonance at all with this antenna.  Before, I could
operate the bottom of the band but nothing above 1850 without a tuner.  I
have changed out the coax feeding the antenna which hepl bring signals up,
but it seems to be a dummy load.

Anyone have an idea what is going on?  Shucks, I am out of ideas.  Unless
my ground plane has gone wonky

My tuner can't find a match for it either.  I have an automatice tuner now,
but it cannot find a match.  Something is wrong here and I am stumped.

Any help from the antenna gurus out there?

[Elecraft] Confessions of grounding

[Leroy Buller]

Ok, I just rebuilt my station and wonder how many of you actually ground
your K3 or your rig?  I have the amp and tuner grounded, but I find
grounding the K3 somewhat difficult.  Why?  Getting my fat ham fingers to
the rear if the rig and tighting up the knurled knob with stiff wire is
quite infuriating.  All the connecting cables are in the way and it just
trips my trigger.  Then being able to reach over all the doodads and
geegaws to attach ground is a frustration of mine.  Many years ago it was
good practice to use solid wire but now i see others using braid.  Stiff
wire adds to my frustration.   So, for my mental health I would like some
suggestions or ideas how best to deal with this.  I know...suck it up.
There has got to be a better way.

[Elecraft] BNC T for IF Out

Is it possible to use a BNC T to drive  P3 and a SDRPlay at the same time?
Is there enough drive to do this?

[Elecraft] 8.215 Trap

[Leroy Buller]

Elecraft just repaired and updated my early model K3.  One of the things
they did was bypass the 8.215 trap.  Tried to look at the schematic and
Google the information, but to no avail.  I know there is an IF at that
frequency, but do not understand why they would bypass the trap.

Could some one explain this to me and satisfy my curiosity?

[Elecraft] Recommendation please

[Leroy Buller]

I am running a K3 with an RS232 connection to my Win 10 computer.  Basic
early model K3.  I also have a p3.  I want to move from a Signalink
interface to a West Mountain Advantage interface to get some more
flexibilty.   I use N1MM to contest on CW and Rtty...MMTTY.  I also want to
look at WSPR X modes.

For those who have set this up, could you tell me how it went and the in
and outs of using the Advantage.  How did you configure rig control if you
did?  How did you do cw keying and fsk keying.

Thanks.  You can email me djrect if you want.

[Elecraft] ALC on RTTY Again

[Leroy Buller]

I am installing a new computer system here and have had to install my
Signalink USB and MMTTY.  It seems to be working but there seems to be an
issue with the K3.  This kind of showed up on my on XP machine in recent
weeks.

Problem.  There is not ALC no matter how hard a drive it with the mic gain
control on the radio.  There was while I was testing, but then I got into a
QSO and the alc indication on the K3 disappeared.  No matter what I do,
there is nothing on the meter but the power output says I am running 95
watts.  That is on the Drake Wattmeter.  But, there is no alc showing on
the rig.  i can turn the power up and down using the mic control or the TX
control on the signal link.  As I have been working with it, I observe that
the power out started to call of.  Now I can run everything wide open and
get about 65 watts out.

On SSB, it seems to work .Had a nice QSO and reported a beautiful signal.
ALC worked fine.

Anyone know that something my be awry with the K3?

Thanks for all the information.   Yesterday, I did some research with

Re: [Elecraft] K3 power oddity

[Leroy Buller]

Don...

Thanks for the information. I will check that out.  I was told a long time
ago by that elusive "someone" to keep the K3 linear that the ALC meter
should just flicker.  Obviously, that was bogus advice.  I  will check this
out yet today.

Thanks

Lee

[Elecraft] K3 power oddity

[Leroy Buller]

Operated RTTY NAQP this weekend.   When changing bands, I noticed my power
would drop to 40 watts or so.  After several transmissions, it would rise
to 100 watts.  I don't think this is normal.   All antennas are matched.
Comments?

[Elecraft] K3 - PSK31 - AGC/No AGC

[Leroy Buller]

Hi guys

 Old topic from a Old Newbie.  I have been fooling around with PSK 31 and I
have it set up and working but I do have a question.  Do most ops using
this mode turn off the AGC and then ride the RF gain control because of the
stronger signals in the band pass killing off the weaker signals?

Is that how it is doneor am I missing something

Yes, I have searched Google and could not find a good answer.
