From the top right I can see that the quality of your decodes aren't very good. What's the signal strength like? Also play with the system volumes. If decodes are good the top right should show a high percentage and be green.

this is the level of the signal and about the volume, i think that it is on the highest level (system volume and the virtual cable volume)

have you fine tuned to the exact centre of the spike of the paging signal? I found playing with volume setting and rf gain works well. It also helps to leave signals decoding for a few minutes and it seems to "settle down" I also find Flex A signals easier to decode

Kind regards

in SDR# I must set an Audio Filter on to get something to decode.
Maybe it help you to?
Some Pager Signals are encrypt!

Also try using SDR# instead of HDSDR.
