FSK is it possible on an RTL-SDR using SDR#

Postby nay27uk » 19 Nov 2016, 10:04

Just adding Frequencies to my SDR# frequency manager and I am halfway through PMR446 I just Added the first 5 FDMA channels, but I have just noticed that these FDMA Frequencies are all FSK Modulation.

Is FSK Modulation achievable on SDR# ?

If so HOW?

I only seem to be able to find in SDR#

NFM (Narrow Frequency Modulation).
WFM (Wide Frequency Modulation).
AM (Amplitude Modulation).
DSB (Double Sideband).
LSB (Lower Sideband).
CW (Carrier Wave).
USB (Upper Sideband).
RAW (I am presuming this is like a Headerless form of modulation I.E A non compressed audio File, like a WAV file or AIFF file).

Not really worth me carrying on adding those 16 FSK Channels if SDR# cant do FSK Modulation I know that some of these FDMA transmissions can also be analogue instead of in FSK but is it worth adding them?.

Did you try looking up FSK to see what it is before posting this? If you did, you would have seen that FSK is a type of frequency modulation. So you can just use FM mode (NFM in this case). However since this signals will be digital you will still need to decode it.
