RSPduo and bias-T

Post by SDRnerd » Sun Aug 19, 2018 11:09 am

Seems the bias-T of tuner2 of my RSPduo is not working. Has somebody tested if this is working on their copy. SDRuno or SDRconsole v3 both turn out negative on the voltage exit of the SMA. My RSP1A works fine with both programs.

Maybe the present API is not supporting this function yet :?:

Just checked my RSPduo with SDRuno and SDR-Console V3.02. With open circuit to my voltmeter I get 4.7V when I turn on bias-T.

Thanks Roger, will have to send mine back for repair I guess. Have contacted the RSP team in the mean time. Hope to get an answer soon.

I contacted the support and did send my RSPduo back and received another radio a few days later wich works OK.

Thanks for the fast and correct reaction of the support team :!:
