Re: Windows 11 update - Missing COM ports
Whit, Thanks for sharing that paper. However, in the latest Windows 11 update the Device Manager selection of Ports (COM & Lpt) was totally missing. The update designated Ports (COM & Lpt) as hidden and was not visible. Had nothing directly to do with the USB comport assignments as they remained correctly. Microsoft is trying to solve the old COM port/Driver issue. Recovering the hidden Ports selection solved the issue. Thanks again for the paper.?
Hi Larry - I wrote this "USB Port Management Guide" about 10 years ago but I think at least some of it is still applicable:
?
Serial ports and Windows have always been a challenge and in my experience, the problems always have been traceable to either the driver or the chipset used in the USB-Serial Converters. It seems that each new version of Windows requires a new chipset from FTDI or Prolific and, thus, a new converter.

Re: Windows 11 update - Missing COM ports
Dave,
Thanks Dave. The interesting thing was the fix advice from Microsoft didn't work. Digging around in the menus uncovered it. There are other issues also. One for example is the Windows search box is broken. You can't type in it. Another MS fix suggestion is to install an update. Problem with that is the update wont complete and it proceeds to uninstall itself. Using the restore back to a previous time works but its a step backward. I have WIN updates blocked on my JOVE 24/7 computers

All FYI,
If you plug in your radio JOVE calibrator into a USB port and go to the
calibrate menu in RSS and the list of COM ports is totally empty you need to
find its COM port assignment. Unfortunately, Microsoft is trying to eliminate
COM ports in its latest Widows Updates in favor of virtual COM ports which are
more secure. Below is a way to discover your COM port assignments for legacy
devices.
To find hidden COM ports, open Device Manager, go to the "View" menu, and select
"Show hidden devices". Then, expand the "Ports (COM & LPT)" section to see all
COM ports, including hidden ones.
Here's a more detailed breakdown:

Hi Sabine,
In that picture, it looks like your Moxon's beam is aimed at the horizon. Would it work better aimed at Jupiter's transit elevation?

Of course! Attached, you'll find a photo of my weekend house in a small

in a valley, so the neighbors can interfere my reception exclusively.
The Moxon antenna is the frame halfway up the mast. At the very top is a pickup
for a VLF receiver mounted (e-field probe). The old satellite dish in the
background is a relic from earlier TV days.

Re: New radioJove station at Lancaster University, UK
Hi Joe,
?
I am just recently in this business, but my graduate student and I have just commissioned a square TFD array at our observatory.? The observatory is about 30km from the university campus, so almost everything there is run either remotely or robotically.? We use VNC to communicate with the two computers (which record left and right circularly polarized data).? Every 24 hours (shortly after 0h UTC), a python script zips up the previous day's data and ftp's those files to an on-campus data server which is backed up regularly.
?
You may have seen some of the results that we have posted from the TFD array (Dark Sky Observatory).? Our good results are due to two things -- a pretty low RFI background site and the RX-888 Mk II SDRs that we chose for the project.? They have 16-bit ADCs and give excellent sensitivity and dynamic range.?? However, they require very capable computers with fast USB 3.0 ports.

Very nice, Sabine!? Did you make the antenna yourself?? It looks 100% professional.

What do your neighbors think about your antennas?

I think it's important that you prove TPs, because after all this is a GRAY line phenomenon! :-))

At my location they were also very weak last night.

Hi Sabine, That is very interesting to me.? Could your power source voltage be changing?? ?How much averaging are you doing in the NSC? Jim
Jim,
?
I'll look into your question as soon as I can. My RJ station is operated remotely, and I'm waiting for a few warmer days to head out.
?
First of all: I've already had trouble deriving a stable calibration temperature from the measurements with the Noise Source Characterizer. I may have a malfunctioning noise source.
Therefore, I always add the background temperature to the measured signal temperature in my images to obtain something like a signal-to-noise ratio.
