As to time servers, I've not found Windows 10 system for time to
be satisfactory. I've installed and use Meinberg NTP. Works
great and I don't find that Windows updates to disable the
service. Just be sure and disable the Windows time system when
you install Meinberg NTP. As to Dimension 4, that works quite
well and is probably easier to install than Meinberg. Both are
FREE which is the best part. I find that Meinberg does ping the
computer and then adjusts for net delays.

Good point, may consider but think adjusting the time server
polling will take care of this. More after I try.

And he could use a cheap USB GPS dongle and
BKTtimesync or similar.

There is a
way to accomplish release of the port without
rebooting. Open Device Manager, right-click the proper
port and select Disable. Right-click again and select
Enable. Ignore any message about rebooting.

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
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
clock 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
I 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 SCU17?

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
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
