[Elecraft] Kn FD?

[Tom Azlin W7SUA]

Thanks Wayne.

First thanks to you and Eric for making all these neat radios.

We will not be home for FD this year so the K4 will stay on the desk and 
the K3 on the shelf. I have used my K4 for FD at home and my K3 for FD 
in a park or at a cabin. I had not though until now to pack my earlier 
K1, K2 or KX1 for our June trip. I am taking my KH1 but will dust off 
these other early radios and see what to take for operating near Jacob 
Lake AZ. Lots of room in the truck.

73, Tom W7SUA
