Given the pattern that Huub mentioned (thanks Huub!), the work involved in tilting the Moxon may not be worth it. On the other hand, one or three of these -- or something similar -- might do the trick without too much hassle: Use that with a short piece of straight tube to mount the Moxon at an angle. Or two pieces if the swivel doesn't lock. -- Dave On 3/17/25 13:52, Sabine Cremer wrote:

Introducing Radio JOVE 2.1 - a radio spectrograph system using the SDRplay RSP1B model receiver
¿ªÔÆÌåÓýDear Radio JOVE Enthusiast, ? The Radio JOVE Project announces Radio JOVE 2.1, a radio spectrograph system using the SDRplay RSP1B model receiver because the model RSP1A receiver is no longer available. This is an update to the 16-24 MHz radio spectrograph used to observe solar, Jupiter, Galactic, and Earth-based radio emissions. ? An Introduction to RJ 2.1:? The new RJ 2.1 manuals:? ? We will continue to support both hardware and software for those participants using the RJ 2.0 system as well as those using the original RJ1.1 receivers (and calibrators). If you have a working RJ 2.0 or RJ 1.1 system, no change in hardware or software is required. We welcome your contributions to our listserv and data archive. ? The reason for the update from Radio JOVE 2.0 to 2.1 is that the SDRplay SDR radio receiver model RSP1A is no longer available and is replaced by the model RSP1B, and this also requires a change in the intermediary software. The Radio-Sky Spectrograph (RSS) software is still the standard Radio JOVE recording and analysis software; however, intermediary software is required to convert the data from the radio to the preferred radio astronomy frequency-time display in RSS. The older SDRplay2RSS intermediary software for RJ 2.0 only works with the RSP1A radio (and older RSP2 models). The newer intermediary software for RJ 2.1, called SDR Console and SDRc2RSS, works with the RSP1B radio but is versatile enough to work with many SDR radios. ? Thank you for all that you do for Radio JOVE! ? Best regards, ? The Radio JOVE Team ? ? Chuck Higgins The Radio JOVE Project Middle Tennessee State University 1301 E.

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? That would be a good idea. I just don't know how to adjust the mast mount so I can tilt the antenna.

The antenna looks so professional because it is. It's a UK-made antenna from InnovAntennas.

When I had it set up, I said to my neighbor Ruth with a lump in my throat: "That thing looks pretty ugly, doesn't it?" But she just laughed and said she thought it was great that I was doing such amazing things like radio astronomy, and that the antenna alone looked absolutely impressive.

Ruth is a really great and nice woman.

Re: 14 Mar 2025 Airglow and TPs
Hi Mark,

TPs are teepees, named as such because in a spectrogram they resemble a Native American teepee. They're the result of the changing ionization state of the F layer(s) affecting the propagation of terrestrial HF band emission.

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.?

Re: Windows 11 update - Missing COM ports
Hi Larry - I wrote this "USB Port Management Guide" about 10 years ago but I think at least some of it is still applicable:
https://www.reeve.com/Documents/Articles%20Papers/Reeve_USBPortMgmtGuide.pdf
?
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.

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 Larry On Mar 15, 2025, at 6:34?PM, Dave Typinski via groups.io <davetyp@...> wrote: |

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:
