Sunday 25th February 2018 - Radio Astronomy Group Working Bee

Dear radio astro fans,

On Sunday 11th February we had a good mornings work on the 21cm neutral hydrogen line receiver and dishes, narrowing down the intermittent noisy fault on the 'B' channel of the receiver and making progress on how to focus the dishes using a signal generator.   We also started discussing how we might motorise the dishes, and looked for existing surveys of the sky at 21cm to find a good location to point them at for a static "drift" survey in the meantime.

We aim to have an impromptu second meeting in February at 10am on Sunday 25th February to spend an hour or two trying to resolve this intermittent crackle on the receiver now we've got a good idea of what is wrong.

If you'd like to get involved with these sorts of things, or have other ideas, then please either come along to the next meeting the 25th or contact me by email at: This email address is being protected from spambots. You need JavaScript enabled to view it.

All the best!
Chris

Sunday 14th January 2018 - Radio Astronomy Group Working Bee

At our December meeting we continued with a couple of projects:

* investigating the issues with the 21cm hydrogen line receiver to  determine the source of noise on one of the channels

* testing the Radio Jove receivers

We also discussed some new projects, the first of which will be investigating setting up a magnetometer at MBO which will allow us to monitor the state of the Earths magnetic field which changes in response to impacts from the solar wind and coronal mass ejections (which also cause aurora).

If you'd like to get involved with these sorts of things, or have other ideas, then please either come along to the next meeting at 10am on Sunday 14th January or contact This email address is being protected from spambots. You need JavaScript enabled to view it.

All the best!
