[Elecraft] K3S Won't Power Up / Obvious Things checked...

[M. George]

Hi, this morning I got off on a tangent (when I should have been running
JA's in the WPX contest on 40m at 6 points a Q!).  My K3S has been powering
back on right after powering it off.  As I was diagnosing things and
removing the ACC connection etc... on one of the power off attempts it
stopped coming on at all??  I reverted to my backup K3 and finished my
lackluster effort in the contesting and now I'm scratching my head over the
K3S not powering up.  If I removed the acc connector the K3S would stay
powered off... and I don't have anything on pin 8 for the remote power
on... anyway, the bigger issue now is that I can't get it to power back on.

I checked the obvious stuff like the breaker on the back and then pulled
out the KPA100 and removed the bottom panel to poke around and check the
polarity protection diodes.  I'm not seeing anything obvious and the diodes
are fine,  I'm getting voltage to the mosfet source pins 1,2 and 3 on
switching package U2 (DMP4015SSSQ)... the typical diodes along that path
check out fine from what I can tell where the drain pints 4,6,7, 8 send
power to the external 12v RCA jack on the back of the K3S.  However
pressing the power button doesn't seem to be charging the gate on the
package and there is likely some other circuit in the mix anyway.

I also tried the 10 second power button hold to get into the MCU boot
loader mode, thinking something got jacked up on one of the power off power
on cycles and I need to reload the firmware of something... nothing...
There is no life at all or any indication of power in the front panel
etc...  It's a sick little puppy!

If anyone knows something I couldn't find via google, I'm all ears, and
I'll fire off an email to Elecraft support and ship it in for service.  I'm
not sure I want to get too crazy chasing thing down from the front panel
all the way though.

Thanks for reading.  Max NG7M

Re: [Elecraft] How to use LCD TV for P3 monitor?

[Jim Shepherd]

The eSynic VC043 (available from Amazon for $12.95) works well with the P3
and a HDMI monitor. The one thing you will need to do is supply 5 Vdc to
the USB plug on this unit. The USB on the back of the P3 does not work to
provide power to this unit so you will need another source like your
computer.

I brought this issue with the lack of power with the USB on the P3 up in
another thread a few days ago and have not received any response.

Re: [Elecraft] How to use LCD TV for P3 monitor?

[Michael Blake]

Phil,  I too have not ordered an SVGA adapter for my P3 as my 4K display only 
supports HDMI inputs.  I have hopes that Elecraft will offer an HDMI adapter in 
the (hopefully near) future.

Re: [Elecraft] How to use LCD TV for P3 monitor?

[Phil Hystad]

A rant of the day:

But, there is a big looming question — one I had when the SVGA feature was 
released.  Why wasn’t it directly an HDMI interface in the first place.  Today, 
finding a good display with the latest features that still supports SVGA is a 
no-go almost.  I believe that was probably the case when P3/SVGA was released 
too or they were at least on equal footing.  Let’s face it, flat screen TVs 
changed everything.

There should be an HDMI interface option made available for the P3.  I have not 
yet bought the SVGA and I probably won’t because my only spare 20 inch display 
(I use as extra display for iMac at times and also with RPi) is HDMI and DVI 
capable but not SVGA.  No plans to buy a converter cable either.

My RPi has HDMI chip on it — the entire RPi board is only $30 so the chip 
itself must be cheap — just looked up on Mouser, TI HDMI interface IC in units 
of 250+ is $2.82.  Of course, there is more cost then the chip but still, I am 
betting on equal terms with SVGA costs.

OK, I am climbing down from the rant bench.

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   I was able to listen around on twenty meters during the WPX event.  
I was not able to find an open frequency.  So I listened to many very 
loud stations getting all sorts of people replying to their CQs but they 
never heard them at all.  I must have found a dozen stations like that 
calling over and over right over the top of those trying to work them.  
I thought about sending my call a few times but never sent a dit since 
they couldn't hear anyone.


  However, the event was done by the time the second net rolled 
around.  There were a few storms out there somewhere but mostly the band 
was open.


  On 7045 kHz at z:

WM5F - Dwight - ID

AE6JV - Bill - CA

K0DTJ - Brian - CA

WP1BK - ???

   While today is nice it looks like the rest of the week will be wet 
and cool.  It will give me time to catch up on my writing if I don't get 
blocked.  Some days I look at a screen and can't type a word.  Other 
days 4000 words magically appear.  I have no control over it at all.  I 
really want to get done with this project so I can publish it.  But I 
want it to be good and correct at the same time.  So it takes time.


   73,

   Kevin.  KD5ONS

"Down-conversion" is no problem, but make sure that the adapter is one
for converting S/VGA to HDMI and not the reverse. There are several
available from "the usual sources".

Re: [Elecraft] How to use LCD TV for P3 monitor?

Mark,

The P3 SVGA adapter will not support all VGA displays (but it will do 
most).  There is no guarantee that a VGA to HDMI converter will work, 
but you are welcome to try and report those which do work as well as 
those that do not.

The P3 has a 15-pin connector (5-5-5 pins per row) for SVGA which provides an 
analog video output.  It is not a 9-pin serial output as you mentioned above.  
The 9-pin RS-232 serial ports located next to the SVGA port (if installed) the 
P3 are for interconnecting the P3 to the K3 (“XCVR”) and Personal Computer.  So 
the first thing to check is to ensure that the SVGA video port is indeed 
installed.

On-the-surface, it appears you’ll need a SVGA-to-HDMI converter to convert an 
analog signal from the P3 to a digital signal compatible with HDMI.  SVGA was 
initially defined as  1024 x 768 8-bit resolution, but the P3 P3 SVGA adapter 
can handle up to 1920 x 1080 resolution (See: “P3SVGA Option Installation and 
Operating Instructions” p. 3 that is available on the Elecraft website) so make 
certain that whatever device you purchase is compatible with the resolution 
levels of the P3SVGA.  

>

But with what kind of video interface does it have: Is SVGA available or only 
digital (DVI or HDMI)?

Hope this helps,

Re: [Elecraft] How to use LCD TV for P3 monitor?

[James Wilson]

Mark,

I could be wrong but I think there's a bit more electronics
needed. You can search for VGA to HDMI
converter - also on Amazon.

They seem to be around $10 to $15.

Re: [Elecraft] Windows 10 Update Breaks COM Port for K3 & P3 Utilities

[Michael Eberle]

You may also want to try going into Device Manager and disabling the COM 
port and then enabling it again.  I have an add-on serial port card in 
my computer and I have to disable and re-enable both ports every time I 
reboot or they will not work.


As a side note, I have a friend who had major issues with his computer 
after installing a Windows 10 update.  He finally found out that if you 
have Avast or AVG anti-virus software, it must be disabled before 
running the update.  Apparently it sees some of the update as malware 
and will put the computer in an endless loop of reboots.

gone into Device Manager and right clicked on the COM12 device drive

Device Manager and right clicked on the COM12 device drive and clicked 
“update driver” and that updated from a 2016 driver to a 2017 CM port 
driver, but neither connect the PC to my K3S or P3.  Any suggestions?  Thank 
you.

Re: [Elecraft] A little late, but.... CQ WPX (CW) going on right now

[John Harper]

Been using the KX2, with and without the KPA500 at times (the combo is good
for ~160 watts). 15m is currently open to EU - haven't seen that in a
while. Otherwise, wall to wall on 20m, day and night.

Re: [Elecraft] [KX3] A little late, but.... CQ WPX (CW) going on right now

[Richard Thorne]

I'm having a blast with my KX3.  I'm putting a serious dent in QRP DXCC 
this weekend.


I'm working EU on 20m normally with the 1st or 2nd call with 5 watts.

The KX3 has a great receiver and does not get wiped out with nearby 
strong signals.

Hi all,

I should have sent this yesterday, but it’s not too late to get in on 
the action: It’s the CQ WPX CW weekend. This is one of the best 
contests of the year in which to work some new countries, test your 
antennas, try a new rig, etc. 20 meters, in particular, is really hopping.


The exchange is simple; just   (starting with 
‘1’). Full rules here:


http://www.cqwpx.com/rules.htm

This is a great contest for QRP, because all of the big-gun contest 
stations worldwide are using their high-gain antenna arrays (which 
help with signal strength on both ends).


I was out hiking using the KX2 and the AX1 20/17 meter whip prototype 
(4’ long) today. Made about 10 contacts in 10 minutes with 10 watts 
(parallelism not intended :) Best DX was Uruguay.

[Elecraft] K3 - Amplifier Recognition

[Bill via Elecraft]

Using N6TV ‘s “Y-Box,” I can switch between the KPA500 or my new KPA1500 
effortlessly as needed. However, regardless of which amp is active, the K3 
message that informs you that the amp has been switched to/from stand-by to 
active always reads KPA500. 
For someone running amps in the same configuration remotely, this maybe an 
issue. 
Has anyone else noticed this? 
If so, have you determined a remedy?

Thanks, 
Bill-W0BBI

Re: [Elecraft] Ham radio as a side dish

[Glen Torr]

Hi All,

Fascinating thread Wayne.

Most of my time now is devoted to design of electronics for a radio
telescope near Canberra in Australia.

https://en.m.wikipedia.org/wiki/Molonglo_Observatory_Synthesis_Telescope

Love my KX line though still a nervous nellie about CW.

Most of my life now is doing hardware and code for the PIC18F67K40 to
control beam formers for a telescope upgrade.

Cheers All,

Glen VK1FB (My call is a tribute to my mentor Doug DeMaw who I met in
Connecticut in the late 70s).

Re: [Elecraft] Ham radio as a side dish

[Bill Frantz]

Many cavers are also hams. We use 2M HTs for communication on 
the surface when project caving in Sequoia and Kings Canyon 
national parks. The WA6BAI repeater lets us coordinate with 
people in Fresno from near the cave entrance. We can let the 
cook know how many people are planning to come for dinner.


Over half of the NCRC cave rescue instructors are hams. Ham 
radios have been very useful in some emergency situations. For 
example see the President's Letter in: 


We have also used QRP 80M radios for cave to surface 
communications. The radio in the cave had two random wire laid 
on the floor of the passage actin as an antenna with a tuner. 
This setup let us coordinate a cave radio demo showing how to 
locate the surface location directly over the transmitter in the cave.


More information about cave radios is in the back issues of 
Speleonics .

Many of us combine our affinity for radio with other activities 
we’re equally passionate about — perhaps more. An obvious 
example (one that renders this post marginally non-OT) is 
hiking / camping; for some of us, it’s a natural environment 
for small radios and big ambitions.
What are your ham-activated avocations? Do they come with 
as-yet-unsolved problems in the field of radio ergonomics?

Where is the boundary between communications media and the things you most 
enjoy talking about?
