Re: Nothing on my monitor from the P3.

. .
 

Hi Guys.

Not had these issue with my line up, however had issues with flashing software. (K3 Bricked)
As Engineer having updated software "all my life" and having experience over here with the K3 - P3
I suggest to disconnect all cables *except for power), put serial cable in K3 only...flash required firmware.
once done take cable put in P3 only  ( make certain it is powered though) flash  required firmware.
Make certain K3 seems to operating normally.... if Ok then hook up P3. nothing else, check for improvement.
In case all ok, add additional monitors and whatever you fancy.
In case nothing hels, there is always Elecraft Tech support., they usually give a rapid response.

Just my 2 cents.

Good luck.

Re: P3 display flashing on/off.

Nolan - KI5IO
 

Friend of mine in Eastern Oregon Mountains was experiencing what seemed similar.  Tried all sorts of normal trouble-shooting steps with no resolution.

He was running WSJTx and monitoring WSPR.  When that APP was running the flashing was constant.

He finally did a clean removal of WSJTx and downloaded the current version, did the install ... turned on to where he was again monitoring WSPR and "no flashing".

May be a different type of flashing, but thought I would toss it into the mix of this conversation.

Thanks Joe.

The thought that the PTT response is a red herring had occurred to me. That's one reason why I am not 100% sure whether its the K3s or the P3. You are correct that I do not have the TXMON option installed. However, when I disconnect the serial cable the flashing stops, or at least it did the few times I tried that. I try running it for a longer period with the serial cable disconnect tonight and see what happens.

Mine is different, flashing in cold weather, nothing on K3 changes it.  So thinking electolytics P3

Hi Alan,

No, I have not tried that.  Maybe this evening after work I'll give that a try. Thanks for the suggestion.

I'm pretty sure the issue is in the K3s, probably on the KIO3B, but I am not quite ready to put money on that yet.  There is still a possibility it could be the P3, and I do need to somehow positively isolate the issue to either the K3s or P3. I am looking for a way to do that.

Keying up the K3s prevents the flashing, as does removing the RS232 cable. I don't see much in the P3 that would affect the entire display flashing by keying the TX or removing the cable other than changing display modes or loss of serial data. Maybe I'm missing something though, so at this point I am willing to try anything I have not yet tried.

I then discovered the flashing stops on the P3 while the K3s was
keyed up (PTT button on the front panel mike) and resumes when
un-keyed.
PTT is a red herring ... The display update is suspended in transmit
unless you have the TXMON option installed (which does not appear to
be the case).

Hello fellow K3'ers...
Last night my P3 display started intermittently flashing on/off rapidly.  The entire display would rapidly flash on/off, including the border lines, function key menu, waterfall, etc.  Sometimes this will happen once, then again anywhere from several seconds to several minutes later. Other times it would start flashing and continue to flash rapidly for several seconds, then stop, then repeat a few seconds later.

During my preliminary troubleshooting I noticed the flashing would stop when I disconnect the serial cable between the K3s and the P3. I re-seated the serial cable on both ends multiple times in an attempt to clean the contacts to no avail. I also re-seated the ribbon cable inside the P3 to no avail. I also tried re-seating the IF cable connecting the K3s and P3 multiple times, although the flashing would continue regardless if the IF cable was connected or not.  Thinking the serial cable may be intermittent, I tried moving the cables around, during both flashing on the display and when not flashing, and that had no effect. I also tried running a separate ground wire between the K3s and P3 - no difference. Note that this setup worked fine for a few years and just started happening.
I then discovered the flashing stops on the P3 while the K3s was keyed up (PTT button on the front panel mike) and resumes when un-keyed. This happened both in the K3s TX mode (RF out) and in the Test mode (no RF out).

Hi Gerard,

Maybe try swapping the two P3's and see if the symptoms stay with the old setup? If so, it would confirm the issue lies within the K3s.

It does not effect the external display.  And now I got a second newer K3S and other P3 for SO2R.  It has not happened yet on that setup.  Electolytics I'd say......some only have 1500hrs life.  I've not bothered to investigate yet....other priorities.....maybe this winter if I'm around, might investigate.

Re: Using M1-M4 buttons DVR and N1MM, SSB, won't repeat...

Mike Heideman
 

You need to set the repeat interval (Ctrl-R in N1MM) to a length that is longer than your message. 7 to 9 seconds seems about right for most CQ messages but you may have to set it longer if you talk slowly or have a long message.

REMOTE ON / OFF for K3

Robert W5AJ
 

 

A discussion on another reflector about remote control of K3 dealt with turning K3 on/off remote

and I’m also posting it to K3 reflector for IDEAS, etc…

 

this email covers method for the Remote K3 ON/OFF control.

 

My first thought was leave the rig on when departing remote site but power failures do occur and K3 will be dark when power restores.

 

The Breadboard type wiring/tests good and no smoke got out This method below is not approved or commented on by Elecraft, any reproduction  at your own risk.... etc. etc.

Ideas always welcome

 

K3

The K3 uses a momentary switch on front panel to turn rig on/off.

The schematic shows the POWER button has 12VDC one side of switch and the other side to control circuit, which when 12vdc is supplied & removed by pushing POWER button, whatever state the radio is in, will change to other state.

 

The back side of the PC board on K3 front panel has two feed throughs to on/off switch.

the furthest away from side is the one of interest (the closest feedthrough has the 12vdc - which is available elsewhere)

 

I Installed an insulated stranded #20 to POWER button - cut away few strands and soldered the #20 to connection of interest of the on/off switch.  I will call this the control wire for this discussion.

Brought control wire out through back of rig (reference port opening for now)

 

put power cables on K3

attach volt meter to control wire and to K3 ground.

TEST:   push on button on front of K3, 13VDC appears on control wire.

release power button, voltage drops to zero.  same when turning K3 off.

Confirms method being used in K3.

 

I have W3YY FSK/CW interface which contains three optical isolated switches - the CW one is unused (as I key CW another method).

Call it the DTR switch for this application.

I'm using the YY device as it's already connected to desktop and has solid state switch ready to go.  Certainly other switches or relay contacts should work too.

The important item is there is a spare "switch" and it's wired to DTR on com port into desktop.

Took 12vdc to one side of the DTR switch output, and connected the control wire from K3 to the other side of DTR output of YY interface device.

observing correct polarity

 

Plug power cable into back of K3,

Open WSJT program to test toggle DTR(your method may vary) change the PTT to DTR and push test PTT (after confirming rig communications) release TEST PTT

K3 under test powers up... YEAH!

click TEST PTT again - release, rig powers off   YEAH!!

repeat several times - no smoke, works.

 

don't hold TEST PTT long when powering up, that might be sign to K3 to enter some special mode or failure mode (I'm not privy to such info).

 

The breadboarded concept for remote ON/OFF works, after FD will work on cleaning up.

some forward thinking: bring new control wire out on same connection that is on ACC port for powering ON (remove existing POWER ON, then replace with new control wire) Or Install new connector at reference port

Need clean way to bring Control wire outside K3  

Find program/method to fire DTR on com port that is available at control site (can be done remote)

 

IF one is using FIDI USB to RS232, set "Disable Modem Ctrl At Startup"

 

On wiring the front K3 PC board.

Need to be proficient on soldering  & use small pencil type heater with small diameter solder.

Even then, it's like three hands needed...

 

After Field Day, will see about schematic and post on web page.

 

& finally, as someone is thinking but the K3 has a power on the ACC pin 8.  It’s known…
