Stewart,
By saying you are "using VOX in Signalink to control PTT" are you saying
that you are using the PTT output of Signalink to control transmission?
With a cable to the PTT jack?
You mentioned the "RS-232 cable" which makes me wonder which of the
Signalink "Radio Cables" you are using. I am going to assume you are
using the SLUSBK3 cable which connects to the K3 reap panel audio jacks
and the PTT jack.
If so, do you also have VOX set on in the K3.
This is a common problem if both Signalink PTT and the K3 VOX are
active. Unplug the PTT cable from the Signalink and just use the VOX in
the K3, or turn off VOX in the K3 and use the PTT from Signalink - your
choice, but do not use both.

Hi
This is probably finger trouble, but I cannot see
what the problem is, so I wonder if anyone
knows what is going on.
I have a K3, Sigalink and HRD/DM780.
For voice and CW including using the winkeyer all
works fine including CAT.
However I get a transmit lockup in data mode.
I am using vox from the Sigalink to control the K3 PTT.
I have K3 power turned to zero.
I set the K3 in data mode and send some data and all is well
relays go over tries to send some data goes back to receive.
If I plug in the RS232 cable and send some data all works
well, the Sigalink drops PTT, buy the K3 locks in
transmit and will not come out of transmit until I power
cycle the K3. Removing the RS232 cable has no effect unless
I power cycle the K3.
Removing the RS232 cable and all works exactly as expected.
I have configured ptt to off-off.
Does anyone have any idea what I am doing wrong here?
Many thanks
Stewart/G3YSX
