Chris, I found that once an app has used the Com Port via USB,
even if you exit the program it does not always release the
Com Port. The error is telling you the port i not available.
The fix while a nuisance is unfortunately to reboot the
machine if this is what is causing it. My guess is RT did not
disconnect from the USB connection on exit. A reboot cures
Dan nothing to apologize about. Yes the 991A and
I assume the 991 actually opens to com ports via the USB
cable. When using HRD’s Rig control as the “radio” in WSJT
you get a choice PPT called CAT and I assume that it
instructs WSJT to use the second port for sound. I do know
the audio is getting to WSJT as the audio meter on the left
of the screen show level and responds if I raise or lower
the volume on the 991A.
I’m actually using the NIST.GOV
as my time server, assuming the time.is
accurate then my clock in the PC is accurate to within 7/10s
of a second so I am fairly confident time sync is good. I
could improve on it. Windows 10 calls the time server once a
day, but you can edit the Registry and instruct it to do it
more frequently. I’m always hesitant to mess in the registry
but if I wanted to improve the accuracy of time keeping
having it do it four times a day but I don’t think that is
going to be needed. I know my PC calls for time at 9:38PM
and resets then. If when I checked it about half an hour ago
it was only 7 10ths behind It should be no more than .085
behind at reset.
I do have some concern about how good Time.Is is
just because the net itself can induce time loss. Not sure
how it compensates for that. As I mentioned I really loved
my old radio based time check system but it was when I had
the company buy it about $800. But it theoretically was
going to be off by know more than .001 seconds from WWV,
anywhere in North America and less than that most places.
Still struggling with getting this to work right
but one thing being retired and being careful about COVID is
provide time to play with this.
misspoke, I thought from reading the specs of the
991 that an SCU17 was required. Reading it again,
the SCU17 is integrated into the unit.
also probably gives HRD the ability to adjust the

I disagree.. It
is perfectly "best" to use the direct USB on the
rig, to USB on the computer technique on the
FT991a. There is absolutely no reason to use an
external sound card, unless you want to add more
complication to an already complicated situation.
Additionally, the Mienberg NTP time
synchro is another over complicated program... I
used it for a time, but after a contentious "
Microsoft Update Tuesday" a couple of months
ago, I ran into continuous off-synch issues..
Deleting Mienberg and downloading and installing
Dimention 4 solved that issue... D4 is old
program but it is very easy to install and
setup. No issues anymore.
Yes, it was very good advise to set the
bandwidth to Maximum on the Ft991a.
73 and Happy Holiday...
