My Small Radio Telescope (SRT), version 2.0

Yesterday I received the Nooelec RTL module (with TCXO, 0.5ppm) from ebay. It works with rtlsdr_scan (PC Spectrum Analyser, also records results in scv format).

Also, I started building the new interdigital BP filter (3 stages, design is here), hopefully this time the performance will be better in terms of flatness and losses, so there will be less interference (last time I didn't use filter).


I will post again about the progress when there is one... one of the most significant improvements to the system will be motorization of the antenna, and coupling to CdC.
