Transmission on 148.629MHz and display the output: If anyone is interested, here is the command I used to decode the POCSAG Program distributed as part of Osmocom's librtlsdr. I was able to get this working very easily with my RTL SDR, using the rtl_fm Original Multimon which now works on 64-bit systems. Specified in the corresponding Arch Linux package.I just discovered MultimonNG, an extensively updated version of the
