[Elecraft] Noise Blanker settings for Newbies

Sun May 15 13:27:09 EDT 2016

You need to spend some quality book time and walk away from the radio 
until you understand how it works.
Read and *understand* the *whole* manual once through before laying 
another finger on the radio.
I would suggest the KE7X books as well as the manual(s).
You first need to find out what version of firmware is installed and if 
woefully out of date, which I suspect, update that before changing 
anymore settings.

The days of unpacking a radio, putting it on the desk, plugging it in 
and having it work like you expect are over.
