[Elecraft] In praise of the sub Rx & Diversity

[Gary Smith]

You're welcome. It is such an oasis to 
find a company that not only makes top 
quality equipment but has a fantastic 
after sale support of these products.

I Loved my K3, sold it to a friend who 
wanted one for mobile contesting, with me 
buying a K3s to replace it. Feeling 
remorse at selling the K3 & having to use 
a Corsair II as my only backup rig, I 
bought another (very old) K3 again for a 
backup in case I have to sent the K3s 
back.

I don't hear much about the Diversity 
option mentioned here any more and thought 
I'd bring up how much of an advantage it 
can be, even with all the stand-alone 
stats of a K3s. Diversity still makes the 
K3s an even better, more capable radio. If 
you want the best of the best, Diversity 
gives you that option.

73,
