Progress Report Video on the SolderSmoke Shack South

30 June 2024 at 16:11

The new shack is coming together in HI7 land.Β  Β I will need a shelf for the test gear -- I am looking for something thatcan sit on the main workbench -- the wall behind the bench is drywall and won't support any weight.Β  Β I will have to get some plywood to protect the nice woodwork. I have melted some solder already -- I had to fix the little magnifying lamp -- it felt good to get back in the game.Β Β 

The AM radio station that was providing background music was from just across the Mona passage -- they were in Cabo Rojo, Puerto Rico.Β  Β My S38-E shows the frequency as being a bit above 700 kHz, but as with most things S38-E, this readout is suspect.Β  Can anyone tell me the call sign of this station?Β Β 

I have been using the homebrew 15-10 rig, but only in receive mode so far.Β Β 

I am also doing some VHF scanning, using a Realistic Pro-36 scanner that Bob KD4EBM gave me.Β  So far I am picking up aircraft approaching Santo Domingo from the East.Β  I have the maritime calling freq also programmed in and hope to hear some ships at sea.Β  Thanks Bob.Β 

Dino asked about astronomy.Β  Β As you can see in the video, the Orion telescope is ready to go, but we are in rainy season here, so the skies aren't too great right now.Β  They will be better in the winter.Β 

Hurricane Beryl is approaching, but current projections are for it to pass to our south on Tuesday. The eye of the storm is not expected to hit this island.Β  Β

Deep Space Station 43 -- Canberra, Australia

From the IEEE article:Β 

The dish’s manufacturer took great pains to ensure that its surface had no bumps or rough spots. The smoother the dish surface, the better it is at focusing incident waves onto the signal detector so there’s a higher signal-to-noise ratio.

DSS-43 boasts a pointing accuracy of 0.005 degrees (18 arc seconds)β€”which is important for ensuring that it is pointed directly at the receiver on a distant spacecraft. Voyager 2 broadcasts using a 23-watt radio. But by the time the signals traverse the multibillion-kilometer distance from the heliopause to Earth, their power has faded to a level 20 billion times weaker than what is needed to run a digital watch. Capturing every bit of the incident signals is crucial to gathering useful information from the transmissions.

The antenna has a transmitter capable of 400 kilowatts, with a beam width of 0.0038 degrees. Without the 1987 upgrade, signals sent from DSS-43 to a spacecraft venturing outside the solar system likely never would reach their target.


The Latest Talks from the Society of Amateur Radio Astronomers

Over on YouTube a bunch of new talks from the Society of Amateur Radio Astronomers (SARA) have recently been uploaded from their recent SARA Western Conference that was held in April 2024. The talks typically involve small home-based radio astronomy setups that use small satellite or WiFi dishes and RTL-SDR or similar low-priced SDRs in their setup. Some of the latest talks include:

  • Nathan Butts: A Novice's Guide to Radio Astronomy (Link)
  • Dr Andrew Thornett: Detecting Cosmic Rays & Building your own version of the Large Hadron Collider (Link)
  • Dr Andrew Thornett M6THO: Lichfield Radio Observatory - Mapping Milky Way at 1420.405 MHz (Hydrogen) (Link)
  • Bruce Randall: IBT Eclipse and other Radio astronomy Failures (Link)
  • Felicia Lin: Mapping the Milky Way by Cross Section Data (Link)
  • Kent Britain WA5VJB: Antennas for Radio Astronomy (Link)
  • Charles Osborne: Eclipse Detection using a VLF Receiver (Link)
  • Rob Lucas - Eclipse Research (Link)
  • Dr Wolfgang Herrmann: Lunar Occultation Observation of Radio Sources (Link)
  • Keynote: Dr Linsay King - Gravitational Lensing (Link)

We note that the last talk was uploaded only a few hours ago at the time of this post, so we're not sure if more talks are yet to be uploaded. So please keep an eye on the SARA YouTube videos page.
