I like radios, not an radioamateur yet. I tried to receive signal from amateur sattelites like skcube, vzlusat1.
My amateur radio hardware is:
- rtl sdr with rtl8187 and R820T2.
- 433 MHz SAW bandpass filter that removes interference from 88-108MHz FM stations, but doesn't efectivelly block GSM interference from >800MHz
My other radio hardware is:
- Various attenuators from ebay (10dB, 20dB, 30dB small power)
- active GPS antenna from ebay
- SMA RF power injector
- RF power measurement module from ebay
RF measurement tools:
- noise power source from ebay. It goes to 3,5 GHz but with attenuated output, it's characteristic isn't much flat but it's flat in small band (range of frequencies)
RF tools:
- crimp tool for SMA and BNC connectors (not that one that is hanging in base)
