Re: 30 Nov 2024 non-Io-B / non-Io-A
Hi Dave, I just got my dipole across the river working again - bad coax.? But to my surprise I did see some of the Non-Io-A.? Went to Larry's YouTube feed and it was coming through there quite strong.? Nothing Earth shattering? to report - just some evidence that a dipole is better than nothing.? I have the stuff to?turn it into a dual dipole but it just?turned frigid outside and I require?more than 3dB of incentive to overcome that. The picture has been?normalized to remove the background.. Jim.?? |

Re: Antenna alternatives for more constrained space and no trees/ground access
Hi, I’m new to the group and just received my kit.? I also have no room for the dual dipole array but was aware of this when I placed the order.? A friend reached out to a local astronomy group looking for interested folks.? Hopefully we can all find a sight and collaborate on the setup. ?? I still want an option for home and have been experimenting with a home made shorter single dipole array.? If only tested it indoors so far and am sorting through the EMI sources, however I that the antenna picked up a sweeper signal a few times since I started testing it yesterday. I did find a paper on an alternative that seems doable and plan on trying it next, as well as a custom dual-dipole I want to try to make and place on the a balcony facing west.? This is the link to the paper with materials for the antenna: Tyson On Sat, Nov 30, 2024 at 4:13?PM Claudio Alberto Pérez Celeiro via <ecosanacion.interdimensional=[email protected]> wrote:

Re: Antenna alternatives for more constrained space and no trees/ground access
Claudio Alberto Pérez Celeiro
Daniel te da una opción que estaría bien. También podrías hacer un Dipolo triple en el ático si éste es suficientemente grande. Pero sería un Dipolo en forma de herradura. Por otra parte, existe la opción de una vertical de 7 metros de largo, con un "sombrero capacitivo" en la punta? de unos 30 ctms de diámetro. Esto baja la estática cercana y te da proyección a más larga distancia en recepción. Estoy también aquí si necesitas algo.

Re: Antenna alternatives for more constrained space and no trees/ground access
开云体育That sounds like a very limiting scenario indeed.? Any chance you could put a dipole on the outside above your roof, even if fairly low to the roof?? It would be further above ground than recommended, but the chances are that you be getting some reflections off the house somewhat similar to what you'd be getting off the ground. Which direction is your backyard from the house?? If it points roughly south, a sloped dipole going from the roof of your house to however high you can get it at the far end will be as good as a dipole running east-west.? I like to model antennas with computer software and can prove that with antenna plots if you want. There is a pretty pricey alternative.? If you know of somebody with room to spare, you could try a remote receiver using the new networked receiver from SDRPlay.? It would set you back about $500 though. Dave AB7E ?

Help with identifying signal
Hi group,
?
It has been a while since I posted something. Been fighting RFI for the last couple of months. Not sure who on this group said fighting RFI is a job that takes a lot of time. Well, I agree absolutely.
?
Anyway I captured a signal I can't identify. Asked Sabine to take a look at it but she didn't received anything within that timeframe. Also nancay.fr showed no results. So we both agree it's not a Jupiter Event. As Sabine didn't receive anything I suppose it's local.
?
Still I'm curious so I hope someone in the group recognizes the signal to put my mind at rest :-)

Antenna alternatives for more constrained space and no trees/ground access
Hello everyone:
I've been using some low-quality antennas to try to detect Jupiter but I have not had success, so looking for other ideas.? My fundamental problem is I have no way to set up anything remotely like the Radio Jove dipole I should be using. I realize that's the "right answer", but I do not have anywhere where I could physically place one.? My problem is this. I live in a house, but I have a somewhat annoying set of constraints: 1) My "back yard" is entirely concrete- no grass to ground anything into 2) There are also some large power lines just outside the backyard? 3) There are no trees I can tie anything to Most everything I've read suggests I should make a dipole and either ground it or tie it to a tree, and be far away from power lines, so you see my dilemma. It may just not be possible. The best idea I've come up with is to put a portable dipole or EFHW in the attic, but I have not seen any reports of detecting the decametric emissions with such a setup. Has anyone had success with a more compact setup or one that doesn't depends on grounds or a tree under conditions such as these? |

Claudio,
Here is a link to the Radio JOVE website with examples of Jupiter's sounds.
