Hi Brian

 

Welcome to the reflector.   Back to back diodes are good option to limit surges and spikes, but others are more qualified than me to advise

 

 

 

 

With best regards

Hi All, 

 

My first post to the reflector.

 

I plan to try using a sound card and a "long wire" (well as long as I can fit into the garden) antenna and later a kit lofted antenna but I'm concerned re static. 

 

 

Normally I'd add a "dc short" with an inductor but at 10kHz than is a big inductor. A resistor is another options.

 

Does anyone have any other suggestions, please.
