Windows 11 update - Missing COM ports

 

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:
  • Open Device Manager:
    You can access Device Manager by searching for it in the Windows search bar or by right-clicking the Start button and selecting "Device Manager".?
  • Show Hidden Devices:
    In the Device Manager window, go to the "View" menu and select "Show hidden devices".?
  • Locate Ports (COM & LPT):
    Scroll through the list of devices and locate the "Ports (COM & LPT)" section.?
  • Expand and View COM Ports:
    Expand the "Ports (COM & LPT)" section to see all COM ports, including any that were previously hidden.?

Nice ionospheric appearance with airglow and TPs.

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
community of only 200 houses. As is typical with radio telescopes, it's located
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 hope not. I've carefully built everything with a bunch of voltage stabilization ICs. I'll check everything as soon as I have time to go out.

Re: Some solar March 12, 2025, and is this a "TP"?

 

Congratulations to your TP, Richard!
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.

Yes indeed, that's the idea.

Hi Sabine, that's very helpful, thank you! I'll update this thread as the station progresses.

"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."

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,

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.

Yep, that's a couple of propagation teepees.

Thanks, Sabine!? I am looking out for TP's, but I haven't seen any yet (I don't think).?

I would love to see a photo of your Moxon antenna.
