[Elecraft] KX1 PA Upgrade!

[Jack Regan]

Having finished my KX1 spring tune-up I took Don Wilhelm's suggestion of
trying the new PA rather than tweaking toroids for a minuscule amount of
power increase.

 

Here are the results as shown by the KX1 (DISP:BAT) at 12VDC (my battery for
backpacking) and 13.9VDC (in the shack for maximum power).

 

12V      Before  After

80         2.6        3.0

40         2.3        2.6

30         2.3        3.8

20         2.2        2.5

 

13.9      

80         4.0        4.4

40         3.3        3.8

30         4.3        5.2

20         2.9        3.4

 

I am aware that over four is a danger zone so I will be doing further
research.

Certainly removing the resistor mod power comes into consideration.

 

For right now, since I only operate in the field with my 12VDC battery, I am
quite happy with my setup.

Hope to see you all soon on the air QRP!
