Mac vs K3s - Redux

[Richard-6]

Well, here’s where we are. I’ve downloaded a new FTDI driver, but am holding off on installing it as a last resort. Operationwise, I’ve whittled down to size most of the problems, but the transmit timing is still not wonderful.

It starts transmitting within a second or two of when it should, like at :17 instead of :15. I can live with that for the moment. Coming OUT of transmit is something else.

Sometimes it stops right on the button just like it should and lulls me into thinking everything’s OK. But then, erratically and with no apparent pattern of occurrence, WSJT will come out of transmit but the radio is STILL transmitting! Sometimes for several seconds before quitting, sometimes I have to stop it manually. This ain’t no way to run a railroad!

My RADIO panel settings are:
K3s
Poll 1 s
/dev/tty.usbserial-A6009F3,38400
Eight
Two
None
No DTR or RTS settings
CAT
Data/Pkt
None.

Any and all ideas will be most welcome.

Cheers!

Try shortening your poll rate if you can, to maybe 500ms.  I realize in some cases that might be too fast for the K3, but play with that.

Also, serial ports are typically these days “eight, one, none.”  I see you have “eight, TWO, none.”  Make sure your port is really configured that way.  Unless you explicitly set it for two stop bits, it’s likely defaulted to eight, ONE, none. One stop bit is generally quite adequate.
