[Elecraft] Quick review of the new preamps in KXV3B

[Jim Sheldon]

Right now 6 meters is marginally open between KS and the Southeast US. 
(NC down to FL).  First chance I've had to check out the "Preamp 2" 
function on the new KX3VB.  Boy what a difference it makes.  Had it set 
to Preamp 1 and just barely hearing signals so went to Preamp 2 and 
really good copy on everyone I could hear.  Makes a really decent 6 
meter rig out of an older K3 without the PR6.

Have not had a chance to test it on 10 and 12 meters other than 
observing a very distinct increase in background noise with it in Preamp 
2 mode as both bands were not open when I tested the KXV3B after finally 
getting it enabled yesterday.  This morning 6 is open so that one gets 
tested first.

Overall I'm very pleased with the operation of this board and no 
negative issues noted other than the initial lack of information in the 
documentation on how to enable it.
