[Elecraft] Circuit details for external RX with a K2

[Dave]

Earlier in April I posted a question asking if anyone had details of 
using a "boat anchor" receiver with a K2. One direct reply asked if it 
was an April Fool joke. Well it wasn't and if anyone would like details 
of a buffer to feed an external receiver in parallel with a K2, together 
with receiver muting relay, an Adobe Acrobat compatible file can be 
found on my web site detailing how to add these circuits to a standard K2.
