Re: [Elecraft] Fwd: K3 And WSJT-X FT8 Timing

[Bill Frantz]

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: [Elecraft] Fwd: K3 And WSJT-X FT8 Timing

[RIchard Williams via Elecraft]

 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

[Bob McGraw K4TAX]

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.

I’m fighting the same problem and MORE. It usually goes like this:

First FT8 (or JT65) activity of the day, the K3S seems to start on 
time but sometimes shut off quite late. Any band, any power; I 
don’t use the amplifier, so 100 watts is the limit.


As time  goes along, the transmission initiation BY THE K3S gets 
later and later, and the shut off time does, too. By late I mean 2

Eventually, it starts late, then DOESN’T shut off at all.

Finally, it doesn’t start at all.

I’ve tried just about every imaginable combination of setting on 
the Radio panel and in the Config menu, all with no improvement.


In the year or more of enjoying JT65 and then FT8 with my Icom 
IC-7410, I had NONE of these problems, using the same computer and

the new 15 second sequence! In that short duration, I am

So, I switched over to my KX3 running the same version of

Both the KX3 and the K3 are connected to two identical Tascam

 Hi Dennis - how you doing?
 
 Sorry I neglected to provide enough info - was in a hurry to post that 
 before I had to run out to pickup kids at school (close to your dads QTH!)
 
 I am using VOX on both rigs. Each rig has it’s own computer and separate, 
 but identical external USB sound cards. The K3 is connected to an iMac and 
 the KX3 is connected to a Raspberry Pi 3.
