22034RE: [perseus_SDR] How to protect the Perseus again HF
- Mar 2, 2014Roelof
I also read that the SDR has not to be connected on an antenna switch due to
HF leak on such device.
My Perseus was linked to such gear and I could have transmitted for a short
period of time...
But it is impossible to inject directly the HF because of the cables wiring
on the antenna switch.
As a result the Perseus is without any led lighting but the 5.2 volts is
present on the SDR PCB.
So the issue is due to the RX itself or the Hf even at very low level is
enough to kill it ... ;)
My concerns is to avoid again such issue.
Warm regards and Thanks

Hello Jean Claude,
Nothing will help for a lightning strike close by.
However, you can get rid of static and lightning build up by connecting the
antenna via a 100K 1 watt resistor to an earth stake.
The best advise however is to disconnect the antenna from the receiver when
a thunderstorm is approaching.
To be honest, I have not seen reports on this list of a failed PERSEUS due
Or am I wrong?
