Receiver input protection
Posted: Sun Aug 21, 2016 6:51 am
Hello guys,
I am planning to utilize the Blade for some ham stuff like spectrum anayzing, digital modes etc. But I'm very hesitant to connecting the RX input straight into my radio club's HF antenna installation. I'm imagining bad stuff will happen to the Blade if there's any stray capacitance and whatnot built up on those antennas when I plug it in.. or is my worry unfounded? Is the protection already built into the circuitry enough for this sort of usage? If not, is there any sort of circuit you could build to provide adequate protection? I've read about using bleeder resistors to ward off static buildup, would that be sufficient?
Regards
