Radio Astronomy White Papers


Note: Due to excessive demand and pdf-liking bots my web page has been archived twice.
For bona-fide users I have had to modify some pdf document links by adding a space before the .pdf extension.

Note: RTL2832U Dongles:
Without care and cooling, some RTL2832U DVB-T dongles may fail at 1420MHz - their gain appears to drop by some 30dB after a few minutes operation.
They seem to recover for a while on unplugging and replugging, but this makes them unusable for H-Line work.

The good news is that faulty units can be persuaded to operate longer if kept cool by blown air on the bare boards.
In fact, this is a superb way of improving their frequency stability for more serious Radio Astronomy work!
