Sunday 10th September 2017 - Radio Astronomy Group Working Bee

The next Radio Astronomy Group working bee will be 10am Sunday 10th September where we will be working on both Radio Jove and the 21cm hydrogen line gear.  I have also procured a Raspberry Pi 3 (model B) with some extras to experiment with and will bring this along on Sunday.

A rough agenda so far is:

  • Test the Radio Jove masts at full height (weather permitting)
  • Install cable guides to tidy up cabling under eaves
  • See if we can try my Raspberry Pi 3 with Radio Jove
  • See if we can address the noisy channel on the 21cm hydrogen line receiver

Ray has taken the 21cm receiver to see if he can trace out the circuitry to compare to the supplied diagrams.

Sunday 13th August 2017 - Radio Astronomy Group Working Bee

The next Radio Astronomy Group meeting will be Sunday 13th August 2017 at 10am.  At the last meeting (Sunday 16th July) we worked really hard and rigged the Radio Jove masts and both sets of dipoles and ran the cables back into the cabin.  There is work to do on both the Radio Jove and 21cm Hydrogen Line projects plus we've now got a new equipment rack for our gear!

A rough agenda for the 13th August meeting is:

  • See how the Radio Jove dipoles & the 21cm dishes held up to the recent wild weather.
  • Take a look at the new rack that we've now got (our gear has been moved into it already).
  • Ray has connectors to make U-bends to connect the 21cm dishes to the front of the receiver whilst still being able to close the new rack door. :-)
  • Check out the noisy channel on the 21cm receiver.
  • Complete the cabling and look at the next stages of work on the Radio Jove gear.
  • Any other business!

Look forward to seeing people there!

Sunday 16th July 2017 - Radio Astronomy Group Working Bee

Hi all,

Sunday 25th June we made good progress on the Radio Jove masts; the first stages of the bases all 4 masts are now in place and the second stages of the bases have been pre-cut to their required lengths.  The upper sections have been drilled ready for further work.

The MBO RAG will be meeting to continue the work on the Radio Jove masts at 10am on Sunday 16th July to see if we can get all 4 completed (weather & time permitting).  NOTE: date has been changed from 9th July to 16th July at the committees request as they need the cabin for this day.

If you are an MBO member interested in getting involved with radio astronomy please email This email address is being protected from spambots. You need JavaScript enabled to view it. to be added to the mailing list.

All the best!
