1. Będę się starał coś 'wykombinować' martwi mnie tylko predykcja trasy bo w ocenie S/N i MDS ta odległośc będzie miała znaczenie:
"Bench testing has shown that for a receiver with a Noise Figure of 2dB (e.g. a RTLSDR with a separate low-noise preamplifier), a minimum detectable signal of ~-112 dBm is required for reliable reception of imagery. Reception at >, 100km ranges is acheivable using a short yagi antenna (5 elements). The current reception range record is 480km, using an 18-element yagi antenna and a RTLSDR+Preamp."
i trochę nie ma wyboru co do odbiornika więc pozostajemy przy RTL i dynamice 8bit:
"Other SDRs with open-source APIs may be supported in the future..."
2. Może zatem 40m
ciekaw jestem jaka antena w tym paśmie i jakie PA na wyjściu Si5153 ?
