What is the maximum output power obtained for each band=0D
for the Elecraft k1-4? I just ordered my new k1-4 and was=0D
wondering.=0D

Hi Reggie !

Here are my results measured at 50 ohms dummy load (Vcc=13,8V):

7030 - 6,6W
10130 - 7,1W
14060 - 5,8W
21060 - 6,3W

7002 - 7,3W
10102 - 7,3W
14002 - 5,4W
21002 - 6,9W

Your results my vary, but not significant

Good luck with your assembly

My K1 covers 40/30/20/15 meters.  With a 13.8 vdc supply, I can get about 7
watts out maximum anywhere on any band.  With the 9.8 vdc KBT1 internal
battery, I can get about 4 watts or more out everywhere.

I use the 150 (180 actually) kHz VFO span option.  On 40m, I could not get
full output near the band edges when the K1 was aligned at 7060 kHz.  I had
to double the capacity of two KFL1-4 band-pass filter coupling capacitors
(C10 and CK) in order to get full output across the 40m band.
