K3 - erratic keyer behavior serial related

This morning my K3's keyer is behaving erratically - long dashes from
dash paddle, dashes from dot paddle, gaps in strings of continuous
dits. This is my first time transmitting since installing the most
recent firmware a couple days ago. I had HRD connected at the time.
The stuff I've tried -

Backed down from 38k to 19k and eventually 4.8k on the serial port.
That didn't help, but the keyer works OK when the serial interface is
not connected. My serial port is the Elecraft supplied USB to serial
dongle, plugged into a laptop running Vista. I tried going to my XP
computer with real serial port and HRD, communicating at 4800 baud, but
no luck there either. Also tried turning off QSK and turning off VOX.
In case of RF interference, I transmitted at 5 watts into my dummy load
and also went into TX standby mode. The only thing that has worked has
been to have no serial connection. Oh yeah, my speed is 22 WPM. And
the erratic sending also occurred while sending a memory message.

I haven't tried going back to the previous firmware yet. Any ideas?

Hi Nick,

I still can't duplicate this. Please describe exactly how both the K3
and HRD are set up.

In particular: Do you have a sub receiver, or at least have the aux
DSP module installed? K3 MCU rev 3.41 allows applications to query the
revision number of the aux DSP even if the KRX3 itself is not
installed. If it were doing this repeatedly, there could be serial
port delays.

Thanks,
Wayne

Re: K3 - erratic keyer behavior serial related

I'm getting a similar thing here. I have no KRX3 and have HRD (latest
version) communicating with the K3 at 38400 baud. If I send a series of
dahs, every so often the dah becomes a dit. If I send a series of dits then
that seems okay.

The paddle is plugged directly into the K3 and there is no other software
trying to talk to the K3 at the same time. The connection between the PC
and the K3 is purely serial, no USB interface is involved. Latest K3
firmware too. I have not noticed this behaviour before. It is independent
of both cw speed and rf output. If I close HRD the problem disappears.

Have you tried increasing the refresh interval in HRD? Tools / Program Options / Comms.
I'm not near my radio now so I can't try it.

Hello Vic

No, I have not, but I will take a look at it tomorrow. I have never looked
at that HRD option before. Time for bed here!

I should probably know this, but what's HRD?

Ham Radio Deluxe, written by Simon Brown- it's a combined rig control,
logging and data mode program, extremely powerful. I don't use the rig
control part but the other two features are both excellent.

Mike,

That would be Ham Radio Deluxe - Simon Brown's (HB9DRV) gift to ham
radio. Professionally written software available at no cost.

Thanks, Don & Stephen -

DOH! I write my own, but I want to take a look at HRD.
