Just use a radio modem in 400 Mhz band UHF , with FSK or QFSK modulation or other, you do not get the high data rate like the modem but with a power amplifier of 6 to 10 W and a directive high gain antenna you cold receive the data with no problem from space. Of course you shod have a transceiver or the proper equipment, antenna, etc at the receiving side. See APRS ISS transmission from space for reference.
Also there are radio repeater satellites for HAM radio use if you can send data threw thous. Up link in VHF and Down link in UHF and so on.

Rockblock is so much easier and cheaper if you do not already own the Ham radio hardware.
