Hi All,

Wow! Success 2 days ago with Triffid array and SDR.- successfully detected galactic hydrogen as per attached radio spectrum.?I am actually quite shocked as I am not used to my radio astronomy experiments working!! (Only just managed to get meteor detection from Graves working after about 5 years!) – and this was achieved within 2 weeks of starting data collection on this project which is truly amazing for me.

However, I really need to give all the credit to Andy Thomas from this group, who generously gave me his Pharmigan Triffid military phased array. This is a wonderful piece of kit:

(i)?????????????? Seems to work MUCH better than similarly sized satellite dish on 1420MHz.

(ii)????????????? Has better sky resolution than similarly sized dish.

(iii)???????????? My wife is happy with the look, whereas she can’t stand a dish, and has (incredibly) given me permission to mount the aerial on the patio long term (which I still can’t believe).

(iv)???????????? Everything thinks the horizontally mounted array looks like a BB, and hence fits in to the garden more easily.

(v)????????????? ?

Andy
