Installing Ptarmigan Triffid array on new wooden mount to allow changes in elevation/altitude for radio observations at 1420.405MHz (hydrogen line)

1. Hello Andrew,

   Thank you for your BAA Radio Section talk. The receiver I was trying to remember that I’m using is an RSP1A, which I’m very happy with, seams to be a step up in performance to the Nooelec SDR I also have and use.

   Thank you again for the Nooelec 1.4 GHz dish from Nooelec.

   Great talk!

   I have Line-of-sight radio relay experience in the field, but the was the Racal Tacnet version with corner reflectors. This competed with the original Plessey Ptarmigan version.

   Cheers

   Simon

   1. Thanks Simon!
      I’ve heard of your receiver – it is meant to be VERY good!!
      What I was trying to say is that it doesn’t take a particularly good one for H-Line detection so yours will definitely work well!
      Andy
