im using a matek power board and just tried supplying HS1177 12v power from that and vcc to the sp3 but still no luck. i have contacted diatone and explained my issue and just had this reply.
"Hello Steve，thank for your photo，as this situation，we can offer free repair service，
your version is the newest SP3，on the 600W power（no wind cool） ，the IC temper can't over
85 ℃，the antenna section, directly connected to the radio IC control section, any static electricity
may cause radio IC to receive damage，about OSD can't connect，maybe your windows system
driver software reason"
What does （no wind cool）mean?
Any of you guys having issues with connecting to pc?
