I vote to allocate two 25 KHz chunks of the ISM to alpha paging.
916.175 MHz and 925.516 MHz #Radio #HAMRadio

So the CC1101 does well sending POCSAG. Unfortunately you can't adjust the TX bandwidth below ~58kHz. I need to double check that it's not an overloading issue.

RPiTX in the 915 range looks fairly clean. Would need to filter it and put a power amp on it to give it some decent range though.

Yup, just lots of spurs outputted from the chip. And it's definitely taking up 58K of bandwith. 😬

Pager still gets the message no problem.
