[Hackrf-dev] HackRF to DVB-S receiver hardware connection.

[steve smith]

In this situation - I'm not sure the output of the hackrf will actually hurt the DVB receiver though - however, it's easy to deal with the LNB power voltage - just turn it off in the DVB menu prior to hooking up the hackrf.  But separating them a few feet will most likely work as well.

This is about 950MHz so the HackRF outputs up to 15dBm. The DVB-S unit (SatLink WS-6906) is rated -65dBm to -25dBm, and also sends out DC power for a LNB. The attenuator should block 50dB of the DC, but I’ll check with a meter. So if I feed this from the HackRF through a 50dB attenuator to the DVB-S unit is there anything obvious I’m missing before I get to the magic smoke expedited egress event?
