I did a list of strongest transponders on my AzBox in July 2011. There will have been lots of changes since then e.g. the data transmission on 61 is gone and RASD on 45 has changed frequency. Our friend William on the ***** forum keeps an up to date list of strongest transponders from his location in SE England.
