[Dx4win] Radio timeouts?

[John Bednar]

Paul,

I own a TS-850 and have noticed the same thing with
DX4WIN and a contesting program. I scoped the data lead
on the radio and turned the VFO. I was surprised to see that
the data no longer comes out of the radio while the VFO is
being turned.

Several years ago someone told me that one of
the signal lines changes state to tell the computer that the
radio is busy and can not answer. I don't know if
this is implemented with all programs. Since you are using
the simple interface circuit, I don't believe that you have
these lines connected.

I have scoped the signaling pins on my radio and to my surprise
they do not change state. At this point, I don't know if there is a problem
with my radio, if they need a pull up, or I made an error.
I did try a Kenwood interface box and there was no difference
with the contest program.

I suspect that there is no way to fix this since the data flow is
stops while the VFO know is being turned. Over the years, I've
learned to pause every few seconds while tuning my TS-850.
If you learn anything else please share it with me.
