Which tuning chip and SDR chip is it? I’m thinking of fitting an externally-accessible micro-switch on it in order to switch between 0-54 MHz and 54-1700MHz and depending on chip it would influence exact tuning range, bandwidth and linux support.

Which antenna would you recommend for beginners who have bought an upconverter?

Thanks for your response. Are there any cheap commercial magnetic loop antennas? If not, how difficult is it, to build one as a beginner?
