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.MARTIN LAMPNER wrote on 12/25/2020 6:36 PM:
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 that.
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
using the NIST.GOV
as my time server, assuming the time.is
website 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.
Perhaps then also probably gives
HRD the ability to adjust the SCU17?

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
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.
was very good advise to set the bandwidth to Maximum on the Ft991a.
