BasicRX frequency selectivity


#1

Matt or anyone who knows,

I know that the BasicRX is listed as being able to receive signals from
2-300+ MHz. However, when I input signals from 0-2 MHz I am still able
to
see them with the oscilloscope and fft plot. Could somebody let me know
exactly what components are on the board that affect signals between 0-2
MHz? Thanks!

John

The ADT1-1WT transformer from mini-circuits is in the signal path. DC
definitely won’t go through, but you will get some response down to
about 100 kHz. You can get specs on it from them.

I assume that’s the correct module.
