Thanks Both - tried moving the boot order (no facility to delete); not
resolved the issue.

The PC boots up fine with the USB cable to the K3S disconnected.
Connect the USB cable to the radio - even if powered off - and the PC
will fail to boot up.

PC is Geekom MiniAir 12 running W11Pro 23H2. Working correctly in all
other respects. K3S has latest firmware.

Thanks again for any further help !

[Elecraft] KEYOUT_LP issue

[Dimitry Borzenko]

Hello group.
I have some issue with KEYOUT_LP.
I have use KEYOUT_LP as PTT for my transverters and PA, but have 
problem when powering OFF my K3S.
All equipment connected to the circuit controlled by KEYOUT_LP going to 
transmit mode (PTT is engaged) then receive mode(PTT disengaged ) 3-5 
times
Looks like bipolar transistor in the KEYOUT_LP circuit got something 
from the micro.


Current though KEYOUT_LP input about 2mA

Anybody have any issue with KEYOUT_LP??

Best Wishes.

Re: [Elecraft] How to allow K3S to feed multiple logging programs on my laptop?

Hello to ALL
Win4K3Suite is good program but require additional com0com program
LP-Bridge makes virtual ports and you can connect all your programs to 
these ports.

Win4K3Suite has full rig control, LP-Bridge not.

By the way, LP-Bridge2 works with other transceivers.

Thank you Wayne.
K3/K3S today do not shows all target frequency, do not show GHz, so from

I do not understand why impossible to show 2304.000.0  and with "Fine" 
engaged - 04.000.000 ?

Or to do this configurable, if K3S has enough free flash memory :)

Hello I have a K3S with the latest firmware. I use it on EME in fact last night 
was the first time. It works well but for EME I prefer to operate with the AGC 
off. If I do a long press on the AGC button then AGC switches off but so does 
the audio. I still see the S meter moving slightly which is strange when the 
AGC is off. On all my other radios when I switch AGC off then the S meter does 
not function. I assume that there is a another setting that causes this . 
or it is a bug. For now I have set the AGC threshold quite high which I may end 
up doing on a permanent basis, then locals don't distort 😊

Any idea what is going on?

 1)   K3/K3S with internal transverter
 2)   IC-9700

Re: [Elecraft] Default K3 transmit delay may be too short for slow QRO amplifiers

[Dimitry Borzenko]

Hi Bob.
Transceiver can not supply multi sequenced events, but can prevent to 
burn LNA if have long TX DLY time and input of sequencer connected to 
PTT of K3.
You can say,  who connect sequencer to the transceiver, sequencer must 
engage TRX and not contrariwise.

Two ways is right, but every way have weakness.
In first way when sequencer gives PTT command to TRX - pushing on 
"Send", "XMIT" or PTT on  microphone or keyer will destroy LNA etc. if 
do not use TX Inhibit.
In second way when we have enough delay between PTT signal and RF output 
- we need to set delay time little bit more then all commutations needs, 
for example I know my mast LNA needs 30ms, PA 40ms plus additional 10ms, 
so for safety use 80mS is enough(if U use delay time between LNA off and 
PA ON).
I have use sequencer in the PA( sequence ~60mS) and generate -9V for 
TS-2000, for K3S I need different voltage for TX Inhibit, all this 
signals needs only because I do not have option to set TX DLY more than 
20mS!


Regards.

From experience, in an operation as you describe, a sequencer is almost 
mandatory to assure each item switches as it should and that proper 
feedback on that item to the sequencer to allow it to proceed to the 
next interval and switching.  I don't feel one can relay just on the 
radio to perform this function.  My sequenced EME station put the 
transceiver in the transmit mode as the last item in the timing of 
events.I don't understand how one can expect a transceiver to 
supply multi sequenced events.


I've fried enough mast mounted preamps, coax relays and caused amp 
flash overs enough times before a proper timed sequencer was employed.  
 Legal limit power on 70 cm can really do nasty things.

Also, a reminder: this is nothing new. We’re just clarifying a delay 
offset that has existed for a long time. There have been no recent 
firmware changes.


It would be possible to modify the K3’s keying algorithm to allow for 
much longer delays (say, 0 to 200 ms). Of course this would 
significantly shift CW RF output in time relative to keying input.


Fortunately, very few amplifiers require more that a few ms of extra 
delay.

With external keying, you can generally compensate by reducing the

Re: [Elecraft] Default K3 transmit delay may be too short for slow QRO amplifiers

Hello.
Why in the 20 century we need to use foot switch?
Why not to do longer TX delay?
Why I can not set 200mS TX DLY ?
For QSK operation or for use with new fast switched TX/RX relays or PIN 
diodes user can to set minimum TX DLY.
Today is possible to change only firmware and do not need to do any 
hardware changes.

TRX mast be more flexible.
You can say , What about CW??.
Nothing , in winkeyer possible to set long TX DLY why in K3S is 
impossible?

All possible, need only wish to do.

Subject: [Elecraft] Default K3 transmit delay may be too short for slow 
QRO amplifiers


It has come to our attention (thanks to N7YK and N6TV) that the default 
value of CONFIG:TX DLY, 8 ms, may actually be closer to 5 ms.


The associated T/R control firmware hasn’t changed in a long time, so 
hopefully there aren’t many users affected (or we would have heard 
about it). The shorter delay may be related to the improved KSYN3A 
synth, which switches faster than the original. We’re looking into 
this, and will update the displayed value to reflect the actual value.


Details:

When using a QRO amp with the K3, the KEY OUT line from the radio is 
used to key the amplifier, setting it up to receive RF. Since the K3 
has very fast QSK, the amp’s T/R control circuitry has to be similarly 
fast.


Those of you who are using KPA500s and KPA1500s need not be concerned 
about the K3’s fast QSK speed, since our amps use PIN diode T/R 
switching. They can easily keep up with the K3 at any code speed and 
with the default setting of the CONFIG:TX DLY menu entry.


However, some other amps, especially older ones, use slow T/R relays. 
If the transceiver generates RF before the amp is ready, this might 
result in key clicks.


(In practice there’s a bit of a grace period because the RF keying 
envelope rises very slowly. It’s a "raised-cosine sigmoid," resulting 
in the transceiver itself having incredibly clean keying sidebands. See 
K9YC white paper on this topic.)


If you suspect your amp has a slow T/R relay, you should do a listening 
test, or better yet have someone else listen from a good distance. If 
you (or they) hear any evidence of clicks, increase the value of 
CONFIG:TX DLY.


Use the lowest setting that eliminates the clicks. CW keying at higher 
code speeds may be affected if the value is too high. Other modes not 
using fast QSK will generally be unaffected (voice and data).


An alternative to increasing TX DLY is to use a foot switch, as do many 
users of old amps regardless of transceiver type.

Winner, Winner chicken Dinner!!!  Tnx Gene for providing what seems to be the 
answer to my problem. By selecting the Unsafe  mode in the Config menu for the 
USB port as described below, the K3S now works in RTS-DTR every time.  I 
appreciate your help. This group is truly something else when it comes to 
helping each other out. Not necessarily included in the price of the radio, but 
one of the benefits of owning an Elecraft product.  Tnx agn to All who replied 
directly and through the Elecraft reflector.

Hi Jeff,


Try this,

PTT/KEY USE WITH THE USB PORT IMPROVED:

Some PC applications can control PTT and KEY at the K3S via the RTS/DTR signals 
of the USB port. However, use of these signals may also allow

the PC s USB port initialization to unexpectedly activate transmit at the K3S. 
This can happen if the

computer is turned on

after the K3S, or if the USB cable is not connected. There is now a "Safe" mode 
(the default) which disables PTT-KEY transmit until the K3S receives a command 
via USB, such as a

read of the rig's VFO frequency.

To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB 
SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on.

Applications that use PTTKEY
via USB but never send commands

may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by 
turning the PC on

before the K3S.

Good morning.  I am having a problem getting my K3S to save in the config menu 
the setting for PTT-PTT. When I set it for RTS-DTR, hit menu it works fine.  
Then I turn the radio off and back on and the PTT-PTT setting is back to 
OFF-OFF. What am I doing wrong? How do I get the Config menu to save the 
PTT-PTT setting to RTS-DTR?  


Tnx Jeff W7JW

Hello.
Have check now and find - PTT setting is not saved.
I have set it to RTS-OFF, after turning off (by power button, not by power
supply) and turning on again -  setting of PTT is  OFF-OFF.
s/n of TRX is 10944 with firmware 5.50.

Regards.

Jeff,

I have no idea what you are doing wrong, but here are a few thoughts:
After making the menu change, are you exiting from the menu? Tap the MENU
button.
Are you 'pulling the plug" when you say you turn the radio off and back on?
Just like your computer, you must use the POWER button if the state is to be
saved.

Do you have anything plugged into the USB or RS-232 port that might be
causing a command to reset the menu entry?  Pull out the USB cable and/or
the RS-232 cable and try again.
