After my previous posts in which I have very excitedly described my recent successes observing Milky Way at 1420MHz, I ended up spending entire day yesterday trying to get the system to work again after it stopped working when I made minor changes to components.
I have concluded:
(i) SMA connectors and patch cables are very fragile and seem to break at slightest pull.
(ii) Once you get a system working, stay away from it because ANYTHING you do will stop it working!!
Also, I have a humidity problem – this is England in Autumn and each morning there is a small pool of water in bottom of box formed from dew condenscing inside of it. The box does not leak but is not hermetically sealed.
I am going to try putting it inside a large plastic bag and including some of these dehumidification boxes below in first instance – if that does not work I will need to buy a large (expensive) hermetically sealed box and possibly an electric dehumidifier of the type using in caravans.
In passing, the meteor scatter system has also stopped working after working so well – why? I don’t know!!
Perhaps I should give up and go back to astrophotography or solar – but there are hardly any clear days or nights currently in UK and do not seem to have been this summer – seems to be effect of global warming on our climate.
