[Elecraft] KX3 Headphone Clicks

[Dave]

I thought that the clunks were due to RF interference!

If they are down to a problem that Elecraft knows about, like the poor 
speaker performance, then I'm not greately impressed as I use headphones to 
avoid the speaker problems...

You are right. It doesn't help me. For me it all comes down to how much 
background noise there is. So for me it helps both with NR and NB as they 
both reduce the noise. When the QRN/QRM is above S6 I have to turn the AF 
gain down to 1. I still can here the signals, so for me it's no big problem. 
But I hope to get rid of it all in a future F/W version.73 de Hal
