Re: [Elecraft] Propagation

[stan levandowski]

Well, science provides predictions and suggests outcomes but I'm still a 
hopeless romantic who tunes the bands in spite of the numbers.  Tonight 
I found a completely dead 20M band at 0220Z except for a single CW QSO 
in progress between WB6UIA (QRZ says Wyoming) and XE2HOE in Baja 
California (La Paz).  When they were finished, I gave XE2HOE a call and 
got a 579.  He was a steady S9 and the guy in Wyoming was S6.



I live in NY, my antenna is a 67' doublet in my attic and my rig is a 
KX2 and it was running at 5 watts (I'm 100% CW and QRP). 



Afterward, I tuned the band again but heard nothing.  Guess everyone 
read the prop stats and turned off their radios

Re: [Elecraft] Can a KX3 be configured to work like a K0 or K0 mini?

[a45wg]

No need to great expense here - look at a set of the new Raspberry Pi. With a 
case <$40 each.

Plenty of CPU power in them - plus Cat 5 & Wifi as and 4 usb ports. If you have 
a microUSB power supply then a decent SDcard (level 10) and you are all set.

Re: [Elecraft] K3 (not S) Antenna tuner strangeness

[Don Wilhelm]

John,

Yes, the "earthing" connection to the SO-239 jacks is important.
That connection is provided by the mechanical connection to the standoff 
between the right side panel and the KAT3.
The assembly manual instructions will provide adequate connection - 
first insert the side panel screw through the 2-D connector and then 
tighten the standoff to the 2D connector, and lastly, put the screw and 
lockwasher into the standoff.


The problem is that *if* that long screw in the upper rear corner of the 
right side panel is removed for any reason, it cannot be tightened 
properly without going through the entire procedure - tighten the 2D 
connector, then tighten the standoff and finally tighten the screw into 
the standoff.


If one tries to remove that screw from the right side panel, it is 
impossible to re-tighten everything without going through the entire 
process in order.  The threads of the 2D connector cannot be properly 
tightened to the threads of the standoff.


A shortcut is to drill out the screw threads on that 2D connector 
allowing the screw to pass through the 2D connector without threads.  
That will permit the screw threads to pass through the 2D connector and 
be tightened onto the standoff.


I recommend that anyone removing the right side panel from their K3/K3S 
to drill out the threads in this hole of the 2D connector so it can be 
assembled tightly without going through the entire procedure of first 
tightening the 2D connector, then the standoff and finally the screw and 
lockwasher.

Guys,
I've run into something on 80M trying to use the internal antenna tuner.
It fails to tune to a low SWR. Brian K3KOI had a similar problem but never 
quite got to the bottom of it because partly intermittent, possibly multiple 
faults.
In the end to fix it:-
a) I rewound one of the swr sensor toroids (centre wire had possibly arced to 
ferrite because I disconnected antenna by mistake and tuned), and
b) fixed a new earthing wire between KAT3 chassis and SO259 Ant1 socket body. 
(possible poor earth connection via KAT3 securing pillar to side panel)

Re: [Elecraft] Can a KX3 be configured to work like a K0 or K0 mini?

[Don Wilhelm]

Enzio,

See page 28 of the KX3 manual.
If you must go "wireless", then some sort of computer at each location 
will be required.  But if you can go wired, then a 'null-modem' cable is 
all that is necessary.

Re: [Elecraft] Propagation

[kev...@coho.net]

Just completed the second Elecraft CW Net.  40 meters was good from here 
to ND as well as into ID & CA.  Twenty meters was pretty long but I did 
get one CA op as well as TX, ND, GA, & MI.  Both bands had QSB while 
forty also had some noise which rose as the net went on.  Scanning 
around there were quite a few signals to be found on each band.

Re: [Elecraft] [K3S] Test Procedure

[Don Wilhelm]

Mark,

I think you are correct, no "standard" test procedure is possible 
because it would not account for all installed options, filter 
assignments, and other configurable aspects of the K3/K3S.


I would however suggest that one could use a procedure similar to what I 
use for a K2.
It is best if you have a dummy load and can observe the TX waveforms on 
an oscilloscope connected across that dummy load with a 10X probe.
How well you can do the tests will depend on the equipment you have 
available.
Testing into an antenna can produce ambiguous results - use a dummy load 
even if you have to borrow one.  An external wattmeter with trusted 
calibration is also useful.


Proposed procedure ---
1) Go through all the calibration items listed in the manual.
2) Check the status of each option installed and do a functional check 
to assure that each of those options is working.
3) Check the computer connection capability - does it connect with K3 
Uility?

4) Check the filter assignments using K3 Utility.
5) Check the CW output waveform on the 'scope.
6) Check the SSB output waveform.  Does it change with Mic Gain and 
Compression.

7) Check data mode operation if you had been set up for that capability.
8) Check FM capability if your K3 is equipped with the 13kHz filter.
9) Check AM capability if your K3 has the 6kHz or 13kHz filter.
10) if you have the KAT3, check that it tunes properly into a dummy load 
on all bands.
10a) if you have 2 50 ohm dummy loads, connect them in parallel and 
assure that the KAT3 will tune into the resultant 25 ohm dummy load.
11) Check receive function on all bands.  A signal generator like the 
XG3 is a big help with this evaluation.  Check at low signal levels.

12) Check the KRX3 receive in the same manner as the main reciever.

Note, you can best observe the RX characteristics using an audio 
spectrum analyzer (Spectrogram or Spectrum Lab or others) running on 
your computer - feed the headphone output (or rear panel phones or 
speaker) to the soundcard input.  The main RX is the left channel and 
the KRX3 is the right channel.
If you do not have an audio spectrum analyzer, you can download a good 
copy of Spectrogram from my website www.w3fpr.com - look near the bottom 
of the opening page for links to a copy internal to my website (it has 
been scrubbed by several anti-virus programs and has come up clean - 
contrary to several copies of Spectrogram found 'in the wild' on the 
internet).

Even if we as users had such a procedure, how many users would have the test

Re: [Elecraft] [K3S] Test Procedure

[Jerry Moore]

The lack of a full functional test is more likely due to it not being
profitable AND being overkill. Generally if it works then it just works.

I'm still thinking it through, however, the process doesn't require complex
test gear as it's a functional testing of all features/modules of the radio.

The build/calibration process is a bare bones, single band/mode setup. 

I'll run back through the manuals and if I don't find something then I'll
create one. 
The objective is to give a quantitative value for the current operation
go/no-go that can be recorded and used to detect when system degradation has
occurred.

[Elecraft] [K3] internal 144MHz xvrtr - no output

[mike]

Thanks for the suggestions Ron. There is no registered output for cw or ssb
on 2 meters. There is good output on FM on 10 meters, so the filter is not
the problem. I will pop the top and check the TMP'. Hopefully that is where
the issue lies. 73  ..mike  AI6II

Further testing has proven to be interesting.
Final assessment.

All other gear is fully functional. It's more likely that the hub failed at

[Elecraft] KX3 accessory installation

[Dennis L. Haarsager]

I have a KX3, s/n 520, for which I purchased the KXBC3 battery
charger/clock and the KXFL3 roofing filter about four years ago.  It was a
busy period and they got set aside.  However, they just turned up in
unpacking from a recent move from Virginia to Maine.  In the intervening
few years, I've discovered that dexterity loss from arthritis is making a
number things involving small parts (or pills) more difficult for me, so
I'm thinking that to be safe I should ask someone else to take this on.

Bottom line: Is there anyone out there, especially someone with experience
in calibrating the roofing filter installation, who I could pay to do the
installation of these items?  I could send along my XG3 if that is needed.
Please reply off-list.

This KX3 has the antenna tuner installed but not the 2M option board.

Thanks and 73,
Dennis Haarsager, N7DH/1

Re: [Elecraft] Strange Interference

[G4GNX]

A bit late with this one (ill health) but I had a horrible teaser with a 
switcher. I was using a wall wart to power an MFJ Intellituner. It seemed OK 
at first and I didn't detect any RFI on any band from it, but after a short 
while I was getting a 10-20KHz wide spurious on 40 metres, and the center 
frequency moved around from time to time and always seemed to cover the part 
of the band that I wanted to use! I finally traced it back to the tuner, 
which every time it tuned to a different band segment, used a different 
internal relay array, which very slightly varied the load on the wall wart. 
This in turn caused it to change its frequency. Needless to say, the wall 
wart was replaced. Interference can indeed be strange.

Re: [Elecraft] [K3] internal 144MHz xvrtr - no output

[Ron D'Eau Claire]

How about other modes (CW or SSB)? Do they work on 2M, if so it's a crystal
filter configuration issue. Easy to check: see if you can transmit FM on
another band such as 10 or 6 meters.

If it's dead in all modes, or especially if it is intermittent, check to be
sure the antenna cable is properly inserted in the TMP connector at the
K144XV module.

I will need move the K3 to my bench (I do hate unplugging all the cables in

[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Morning,

   The sunspots we've had for the last week or so are passing over the 
limb of the sun and the SFU is dropping.  However, the sun did send a 
double blast in our direction.  It may, or may not, hit a glancing blow 
Tuesday; but at least the sun is semi-active. Hopefully this will allow 
us to eke out a few contacts this week.


   The weather is supposed to change but that's been in the forecast 
all month.  It is still chilly but the clouds are going away. Maybe 
summer will start one of these days.


Please join us on:
14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 7045 kHz at 0100z Monday (6 PM PDT Sunday)

   73,
  Kevin.  KD5ONS

Re: [Elecraft] [K3] internal 144MHz xvrtr - no output

[Grant Youngman]

An idle thought. Are you sure the cables are all seated properly into the 
xvrtr?  It is not difficult to think you have the TMP cables seated only to 
find that all you've done is force the center contact in the jack backwards ... 
so that it becomes intermittent or open.  Easy to spot and fix ... the little 
plastic surround for the center contact will be pushed backwards at a funky 
angle. 

I learned to always leave the cover off the xvrtr when attaching cables. A 
couple of them (don't recall which ones specifically) are prone to this 
problem. 

Don't ask me how I know this ;)

[Elecraft] [K3] internal 144NHz xvrtr - no output

[mike]

I am stumped. I finally got around to installing a FM filter so I could work
2 meter FM. All went well and the K3 receives fine on 144. However I cannot
detect output on FM (or any other mode) on 2 meters. The K3 shows RF out of
8 to 10 watts on the rig's meter, but there is no output registered on my
external PWR meter running to a dummy load. I have changed coax jumpers and
tested them and the PWR meter on my IC-2300H at low power and everything
works.

On the air I can hear FM signals (both from the local repeater and my
handheld working simplex in the shack), but I cannot trip the repeater or
even detect a signal on my handheld when I key the K3.

I have gone through the menu setup and everything looks like it is correct
(I am not in test mode and I am not inhibiting transmit.) What am I missing?
Help would be greatly appreciated. 73  ..mike  AI6II
