Bob McGraw - K4TAX

Re: Fwd: K3 And WSJT-X FT8 Timing

No issues of that type here. These are my setup numbers:

Baud Rate = Eight

Stop Bits = one

Handshake = None

PTT method = CAT

Mode = Data/Pkt

Split = Rig

Also under the Advanced tab: Miscellaneous

TX Delay = 0.1 sec.

I'm not running any other applications such as JT Alert, N1NM, etc.
The computer is connected direct to the K3S with no router, or splitter,
or hub and such in the path.

*** Be sure the VOX mode on the radio is OFF. {Very important}

Bob McGraw - K4TAX

Re: Fwd: K3 And WSJT-X FT8 Timing

I don't find those value to work correctly. The communication between
the computer and radio is USB. If it were RS-232, maybe so.

Also be sure the Poll Interval on the F2 Setup menu, Radio tab is set
to a value of 1 second.

Via the CONFIG menu, PTT - KEY is set to OFF - OFF, the RS-232 set to USB.

Here’s my latest attempt:

Config: PTT — KEY = RTS - OFF
VOX - Off

Radio Panel:
Poll Interval - 1s
38400
Eight
Two
None
No Force Control Lines
RTS
Data/Pkg
None

Advanced Panel:
Tx Delay = 0.1s

Results:
CQ Call #1 — K3S Transmit time = +1 second / Stop time = +4 seconds
CQ Call #2 — K3S Transmit time = +1 second / Stop time = 0+ seconds
CQ Call #3 — K3S Transmit time = +1 second / Stop time = 0+ seconds
CQ Call #4 — K3S Transmit time = +1 second / Stop time = 0+ seconds
CQ Call #5 — K3S Transmit time = 0 seconds / Stop time = 0+ seconds

I was encouraged… then this popped up:

When I clicked Cancel, WSJT-X quit. on previous appearances of the above I have clicked on OK, which took me back to the Radio panel. I tried Test PTT, and it seemed to work OK, and I had a green dot on the main window.

This error message appears seemingly at random, whether I’ve been transmitting or the radio has sat untouched for several minutes.

I’ve tried one stop bit, too, but it made no difference I could detect. This is no fun at all.

Cheers!

Re: Fwd: K3 And WSJT-X FT8 Timing

In reply to this post by stengrevics

When setting up radio settings in WSJT-X for the K3/K3S, I keep seeing different settings for the number of stop bits (one and two) popping up on the reflector. Am not sure where TWO stop bits is coming from??? On page 20 of the K3S manual (page 18 of the K3 manual), left hand column, Serial Port Setup, it states "Software should be set up at the same rate: 8 data bits, no parity, 1 stop bit".
Have no idea why the Radio set window in WSJT-X defaults to TWO stop bits when you select Elecraft K3/K3S. Initially, I did not catch this, and I was encountering problems with my K3S remaining in transmit mode more often than not after a transmission. Once I changed to ONE stop bit, my problem magically went away.

What I have set up is:
Rig: Elecraft K3/K3S , Polling interval: 1sec
CAT control: COM 13 (which is a virtual com port set up with LP-Bridge with my setup, your setting will be whatever com port are using).
Baud rate: 38,400
Data Bits, Stop Bits, and Handshake: 8, none, 1.
PTT method: CAT
Mode: Data/Pkt
Split Operation: Rig

Re: K3 And WSJT-X FT8 Timing

Made changes to my “radio” tab as suggested below and I see some improvement, and wondering if this is what I should expect: At the “zero” time mark, the rig red TX light comes on and at the +1 second mark, RF /ALC is happening. Expected behavior? or should the RF/ALC start at the same time as the red TX light?

Both the K3 and KX3 are exhibiting the same response.

Re: K3 And WSJT-X FT8 Timing

In as much as one only has 1 second minimum resolution, I'd say that is
quite normal. No,. the ALC/RF should not occur at the same time as the
TX LED is illuminated.

In order to correctly determine accurate timing values, one needs to use
a triggered dual trace scope to see exactly when things occur. In my
life, one second one way or the other makes absolutely no difference.

Re: K3 And WSJT-X FT8 Timing

In reply to this post by Richard-6

Guess its time for me to add a couple comments:

Before FT8, before HFers "discovered" JT65,etc., we moonbouncer's had
been using JT-65 for nearly 15 years!

Joe Taylor-K1JT invented all these nice new digital modes which
originally were designed for ms (meteor scatter) and eme
(moonbounce). Knowing ms and eme stations run QRO on VHF+ with low
noise preamps, there was a need to delay the digital transmission so
all the various relays and accessories were switched to
transmit. Typically that was 300msec (0.3 seconds). So the sw
engages PTT and waits for everything to be ready before sending audio
to the transmitter.

Now that "hot shot" HFers are wanting to "Hot switch" their gear a
guess FT8 and WSJT-X versions have provided for user input on the
delay length. <tongue in cheek - don't get upset>

Now you "know the rest of the story".

Note:
I use a USB/RS232 cable and key with DTR. I couple audio input and
output via two RS audio cables from my external soundcard (emu0202)
to my 2010 K3 (4340). I have computer generated audio turned off (no
"you have mail" or internet beeps). Besides, I have a separate
computer for normal internet/e-mail, etc. My dedicated ham radio
computer is normally disconnected from internet and I keep computer
time by use of a GPS dongle (I can restore internet for K3 fw upgrades).

Re: K3 And WSJT-X FT8 Timing

In reply to this post by Edward R Cole

And before that we used CW. I built a keyer/sequencer (still have it in
storage) that used an Accu-Memory board with a lot of peripheral CMOS to
automate the station sequencing.

I counted down the 60 Hz to generate timing, either 15 sec or 2 min depending on
mode. This started the changer over sequence and the memory playback. However,
the generated CW was run through a shift register (FIFO) with a variable speed
clock that determined the TX delay, allowing the various stuff to accomplish
their missions. Some retriggerable one-shots held things in the correct states
until the message ended and the sequence reversed.

I ran an 8877 and GaAs FET preamp at the antenna and never had a failure except
when I rushed to get on FM using a multimode (non-sequenced) rig to work W5LFL.
I blew the antenna preamp and had to climb the tower to bypass it. I still
worked him, receiving the signal report, "N7WS 59, the loudest signal we've
heard in the spacecraft."

Jim,
Check the Settings/ Advanced tab and make sure you have the Tx Delay box set to .1 seconds, and not to 1 second.

Re: Fwd: K3 And WSJT-X FT8 Timing

In reply to this post by Bob McGraw - K4TAX

I run my K3, which has the KIO3B upgrade , making it like a K3S.
I usually have the K3 USB coming int through another USB hub.
(Note that KIO3B has in internal hub branching out to a USB
Audio Codec, and a FTDI USB <--> RS232 interface. As such, all
the RS232 parameters in wsjt-x are used, so it is important that
they are set correctly.

I did have to fiddle with the driver configuration on my
MacBook, probably because I installed a FTDI driver before Apple
started providing one with the system, and 2 drivers confused
things. (I don't know if Windows has a similar issue, but I
understand that recent releases of Windows include a FTDI driver.)

I do all kinds of things with my computer, mostly downloading
and reading email, while my FT8 contacts complete themselves.

If you had a K3 without the KIO3B upgrade, you should be able to
get wsjt-x to control the rig through the CAT interface using a
USB <--> RS232 converter (brand Elecraft recommended). Really,
the things you are buying with the KIO3B are fewer cables and
fewer audio level adjustments.

Re: K3 And WSJT-X FT8 Timing

After changing that TX delay in WSJT-X on both computers, AND changing from VOX to CAT control, I do see a slight improvement. I guess that at this point we can simply close the thread. The software works on both computers and both the KX3 and K3 are able to successfully make FT8 QSO’s - when I’m in the mood for such “automated” operating as this. Thanks for everyone’s comments and input. Nice to have valid, informative interaction on this reflector, as opposed to some of the snarky comments one occasionally gets on other non-elecraft venues!

73, Jim / W6JHB

p.s. - I do have a question about NTP but will post that as another question, kinda off-topic.
