 Because I'm not looking for a K4 forum.  I'm looking to AVOID all the
 K4

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   Conditions on both bands was OK.  Not a lot of noise, some QSB, 
signals were easy copy.  Weather reports varied, to put it mildly :)  
Frost and snow along with smoke and 113 degree temperatures.  There will 
be a lot of wind with a temperature differential like that.  We are due 
for a week of high, to extreme, fire danger here in Oregon.  All of the 
recent clearcuts make life safer.  However, the hunters are now out 
searching for the deer and elk.  My twenty acres of tall trees draws 
each of the three species.



  On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

K6XK - Roy - IA

K0DTJ - Brian - CA

KL7CW - Rick - AK

NO8V - John - MI

K4JPN - Steve GA

AE7US - Rocky - OR

AC5P - Mike - OK


  On 7047.5 kHz at 0045z:

W0CZ - Ken - ND

K0DTJ - Brian - CA

WM5F - Dwight - ID

KL7CW - Rick - AK

K6PJV - Dale - CA

AE7US - Rocky - OR


  Until next week stay safe from the fires, the wind, and the snow.  
Stay hydrated too, that always helps :)


  73,  Kevin.  KD5ONS

[Walter Underwood]

In the late 1980s, I was managing forums for about 5000 Hewlett-Packard 
engineers.

A modern merged forum/email system (like groups.io ) is 
excellent, but if I had to choose, I’d choose email every time.

Re: [Elecraft] 2 different 144MHz transveters and CAT selection

[Geert Jan de Groot]

I have an unusual situation in that I have 2 different 2m transverters
attached to my K3S.
One system is a dual channel ME2T-XP and uses the SUB RX, this is only used
for EME and it designated XV1.
The second is used on tropo/terrestrial DX and contests and is an
ME2T-ProII, this is XV2.

If I use WSJT-X and use CAT I have a problem in that a CAT selection for
144MHz always chooses XV1 which is not what I want at all most of the time.
There are gain and LO offset configurations that mean that using a switch in
the IF is not ideal.

Currently my solution is to set the RF frequency for XV1 to 70 MHz
temporarily which always confuses me when I want to go on 2m EME. What would
be ideal would be some way of setting the CAT XV priority from the front
panel. I think that this must be a firmware update, its an easy one but of
course would be low down the list.


Using a K3 for QO100 operation, I set the display to 89. MHz, not 
10489. MHz. Easier to type, and the frequency display doesn't get 
clobbered by useless digits. If I go to fine tune mode, the frequency 
still fits on the display.


In similar vein, you could consider defining one of the transverters as 
44.xxx MHz instead of 144.xxx MHz. I expect CAT will work then?


But, I have my gripes with K3 and transverters.
The K3 firmware is buggy: if you only define transverter bands to work 
on and switch off the HF bands, then the band-up and band-down switch 
behaves strange, selecting bands that I disabled (80m and 10m, both 
disabled). It should switch between transverter bands but doesn't.
I reported this quite a while back but no planning was given to fix this 
(a trivial fix, especially useful for people using transverters)
I wonder if Elecraft will ever fix this (given that all effort is now on 
K4), and frankly this doesn't bode well for the K4: if there is a K5, 
will the K4 stop getting fixes?


Also, given that Elecraft stopped making transverters a long time ago, 
I'm hoping they will make the contents of U4 of the XV series available. 
This would allow my transverters to talk to the K3 using the AUX bus, 
and I can think of a few ways where this would improve integration.


I've considered reverse-engineering but apart from Elecraft probably 
frowning on that, haven't had the time (yet). But, don't knock it, this 
is how the DSP option became available for the K2...

Ahh.  Well then, I'd bet quite a lot of money that 95+% of that traffic 
will have "K4" in the header and easily be sent directly to your trash 
bin.  You'll never even see it.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[Bill Coleman]

This is a feature of WSJT-X. If you have the Split Operation selection set to 
“Rig”, WSJT-X will always use Split mode.

It sets the transmit frequency higher or lower in 500 Hz increments. The main 
reason for this is to keep the generated audio in the middle of the SSB 
passband, but high enough to allow harmonics to be outside the passband.

So, for example, if you select 400 Hz as your transmit frequency, WSJT-X will 
set the TX frequency 1.5 kHz lower, and then generate transmission tones around 
1900 Hz. If you set the frequency to 2000 Hz, it will set the TX frequency 500 
Hz higher, but the tone generated is about 1500 Hz.

The net result is the same — the transmitted tones are always between 1500-1999 
Hz.

And even if you select a transmit frequency between 1500-1999 Hz, WSJT-X will 
always use split operation. (Although in this case, the RX and TX frequency 
will be identical)

Text email downloads take a trivial amount of time and bandwidth. 
Filters (either software or mental) easily take care of the rest.

Re: [Elecraft] With the K4 coming, is it time to replace this email list with a forum?

[Phil Hystad via Elecraft]

If there were an alternative to e-mail for the kind of dialog that takes place
on this e-mail reflector I think the style and format, along with operating 
rules,
of the Stack Exchange forums would be a great fit.

Now, I don’t think Stack Exchange would allow a vendor directed forum and
there is already a Ham Radio forum which is not that good in my opinion but
the way the software works, the organization, the division of posted questions 
with
answers and the voting to rank answers (and even questions) is very good.  Each
forum also has a chat mode for back & forth dribble that might come up now and
then.  

If you have not visited a stack exchange forum, consider some of the following
which I list merely because these are some I follow.

https://physics.stackexchange.com 

https://ham.stackexchange.com 

https://math.stackexchange.com 

And, this last link is a sort of directory of available SE topic areas:

https://stackexchange.com/sites

[Elecraft] Putting NHF station in a Honda odyssey

Hello Ella crafters, I just got myself a 2004 Honda Odyssey. I’m getting ready 
to put an HF station, and her UHF station in it. Has anybody had experience 
with these cars in relationship to noise when putting transceivers in, and if 
so could you possibly give me suggestions. Gerry Leary WB6 IVF

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[exbpi]

Bill,

Why are you running split in WSJT? The only time you actually need split is 
when operating 2 different frequencies like working JA's on 160 when they used 
to be required to transmit on 1908 KHz and we transmitted on 1840 kHZ (they now 
can operate on 1840). Unless you are actually needing to receive on one 
frequency and transmit on another, set the radio configuration to "Fake It" 
instead of "split". That will keep your transmit frequency in the middle of 
your transmit bandpass. There is no actual frequency change in WSJT including 
DX expedition mode.

OK, I figured this out, sort of.

Every time I’ve had trouble with the KAT3 not tuning, the K3 has been in split 
mode.

By taking the K3 out of split mode, I’m able to turn on 6m correctly.

Oddly, though, when I return to split mode, it still works. 

I’m not sure why I see this issue, but I’m glad I can work around it.

Split mode is often configured due to the WSJT-X settings, depending on the 
frequencies used.

[Elecraft] For Sale: unbuilt kit KSB2 SSB Option for K2

[Julius Fazekas via Elecraft]

Hi,
Unbuilt KSB2 kit (rev G) asking $170 shipped US. Can send pictures. Please 
contact off list.
Also have a bunch of other K2 parts like the back cover, embroidered cover (has 
my call on it), toroids and other odds n ends. NO other kits. Been doing 
serious cleaning and it's amazing what I have squirreled away.
If anyone is near Knoxville Tn and is looking for antenna aluminum and stuff 
(or wants to drive here from elsewhere), I have stuff going up to 6" OD (makes 
a nice low band vertical).
Hope everyone is having a nice holiday weekend!

Re: [Elecraft] K3S TX current

[Randy Farmer]

The K3 PA is the original module, but I don't know what devices it uses. 
Perhaps someone with inside knowledge could provide a S/N range or 
approximate date for the changeover. I built my K3 from a kit in July 
2009. As I recall, It draws about 17.5A with key-down CW on 20 meters. 
The K3S PA module was replaced in July 2016. I don't know if the 
original K3S PA showed the elevated current draw before it was replaced.

agree with you that the 20/30m LPF ought to be a prime suspect. Everything
else is common and 14MHz should be very close to the center of the total
frequency range of the transmitter. My K3S has not had any reliability
problems either, but it sees fairly light duty with SSB only and no heavy
duty "run mode" contest use.

BTW, I checked the current draw on 30m (on the K3S) which *shares the same
LP filter*. It is an average 17.5A. But 30m is lower in frequency and thus
farther away from the filter cutoff. 40m, 15m and 10m LP filters are also
shared with a lower frequency band, but do not cause an elevated current
draw.

This comes up often. And Elecraft is adamant that they want it just as it is. 
And it’s their “football”.  

There is a group on groups.io for the L4 (Elecraft-L4).  Perhaps you can check

So I don't routinely get into this level of ham gear assembly...but I find that 
I am increasingly going there.
When I read "DC power connector's negative terminal", I immediately think of + 
and - rails, and a neutral ground. I do understand that when I look at barrel 
connector, the icon usually shows a + and - terminal. But it seems to me that 
the - terminal is really ground...not a negative rail.
I can see how, even with my terminology, swapping leads on a power connector 
can lead to shorting + to ground.
So are we really saying that the case is connected to ground, when we say 
negative terminal?

Re: [Elecraft] New KX3 reverse voltage smoke

[Mike Morrow]

Yes, it's "surprising" how much surprise there seems to be that the KX3 (and 
almost any other ham rig) DC power connector's negative terminal connects 
ultimately to the case.

Let me "flog a dead horse".  This whole affair amounts simply to this:

1.  The KX3 case and the power supply's negative output were tied together 
through an owner-established conduction path that was independent of the KX3 
power cable.
2.  The KX3 power cable was carelessly installed such that power supply 
positive output was on the KX3 power connector's negative terminal.
3.  When the KX3 power connector was applied to the KX3, the power supply's 
positive terminal was shorted to its negative side through the power cable and 
KX3 case and whatever external conduction path the owner had established 
between the KX3 case and power supply negative.

The KX3's D6 polarity protection diode did not come into play in any manner.

It is common good practice for DC power cables to have fuses in BOTH the 
positive AND the negative leads.  That would have prevented power cable damage 
here.

Re: [Elecraft] K3S TX current

[Randy Farmer]

Interesting. My K3S (10175) and K3 (3260) exhibit the exact same 
behavior. My K3S had a problem with low power stability on 80 meters 
that resulted in field replacement of the 100W PA module, but the 20 
meter current draw didn't change. My working hypothesis is tolerance 
stack-up in the 20 meter LPF, but that's just a supposition. Both radios 
have been used for fairly serious contest duty, the K3 since 2009 and 
the K3S since 2016, with no reliability problems.

Hi,

I have recently made a discovery during a routine checkup that my K3S draws
*much* more TX current on 20 m than any of the other bands. Using Data A
FSKD mode at the 100W level it draws about 22A versus 16-18 A on all other
bands. DC voltage from the Powerwerx SS-30DV is 14.2V as measured at the
binding posts. The K3S voltmeter indicates 14.2V in receive and 13.7V in
transmit mode. Current is measured with the K3S built-in ammeter (~1A in
receive). Power output is 100-102W as measured with an LP-100A on all bands
40m - 10m. TX IMD is not noticeably affected as measured using the built-in
2-tone generator. I measure maybe 33dB (5th order worst case) below PEP on
40m slowly worsening to 30dB on 10m, all within acceptable limits for a
solid state 12VDC powered transmitter.

What's up with this? I don't know how long this has been been a "problem" as
this is not something I routinely monitor. My much older K3 (with the old
bipolar PA) does *not* exhibit this behavior. Is this indicative of a
problem with the 20m low-pass filter perhaps? All measurements are done with
a Ridge Electronics dummy load. All RF connections are tight and the LP-100A
indicates 1.01 SWR on this dummy load in all cases. BTW my serial # is
10480, which is an early serial #. It was back to Elecraft twice in its
first year for fixes to the transmit signal path to improve TX IMD.

Knut - AB2TC

PS. I am not worried about the electricity bill, but whether this is
indicative of a potential future serious failure.

Re: [Elecraft] New KX3 reverse voltage smoke

[Dave]

Many items of radio equipment are supplied with  a fuse in both the +ve and
-ve leads to avoid damage from missing return connections in vehicle
installations, as well as providing a fuse if the -ve rail is accidentally
connected to a +ve power supply point, where -ve at the supply connects to
ground.

Some mobile radios had a “fuse” from their power socket -ve point to
chassis inside the radio, this was a short length of tinned copper wire to
protect the wiring in case of reversed connections. I replaced a lot of
those fused links when I worked for a mobile radio manufacturer.

For those of you picking up legacy K3 rigs recently, you might want
to consider this option.  The PR6 was designed to help boost 10M and

connections on the back of the K3 with supplied BNC connectors.
There is a power connection and a control so that you can turn on the
PR6 by simply pressing the RX ANT button on the front of the K3.  Here is a

Re: [Elecraft] New KX3 reverse voltage smoke

[David Woolley]

I'd definitely expect the chassis ground to have a low impedance 
connection to the negative power supply rail, and normally that would be 
a DC connection.  Without it the screening of internal circuitry would 
be less effective.


The K2 definitely has a DC path from supply negative to the case.

I'd also expect any power supply large enough to require a ground 
connection, and eventually have exposed voltage output rails, to have 
ground connected to one.  Without that, capacitive leakage can generate 
a significant electric shock hazard, or even cause damage when the 
powered equipment is being interconnected with equipment on another 
power supply.


If the safety earth rises significantly above that of other conducting 
items during a fault, there is a defect in earth bonding in the 
installation as a whole, that needs urgent rectification.

If that really is the case, there would seem to be a fault with your 
power supply. The secondary (low voltage) side of a PSU should never be 
connected to ground. Both poles should always 'float'.


I'd be very surprised if Elecraft had connected the negative supply to 
chassis ground inside the KX3 either.

Re: [Elecraft] W1 Programming???

[David Woolley]

When you are interacting with a USB thumb drive, you are normally 
interacting with a USB mass storage class device, not with raw USB. 
Most cheap USB boltons to hardware are done with the communications 
class, and emulate an asynchronous serial port (although some may use 
the human interface device (mouse/keyboard) class.


As such, the ability to write code for the thumb drive doesn't mean you 
can use the same code on the wattmeter, even though the chances are that 
the USB side can be treated as though it were something else.

work. I have it working with an Uno, a Nano and a Mega all using the Serial
port. Lest you are tempted to use the hardware serial ports Serial1, Serial2
or Serial3 on the Mega, they will also will not work.

I did not test with a W1 but based on what has been described here I expect
it behaves the same as the W2.

Unfortunately the same Serial port is used to download the program via USB,
so you need to disconnect the W2 (or W1) when doing downloads.
