[Elecraft] Additional info - Problems = Alignment Part III K2 #4993

[NZ8J]

I aligned the rest of the bandpass filters and took the following readings..

3750 - 2.38 amp
7100 - 2.14 amp
10100 - 1.70 amp
14100 - 1.26 amp
18100 - 1.10 amp
21100 - 1.18 amp
24900 - 1.14 amp
28200 - 1.12 amp

As you can see the higher in frequency, the better the readings are.
However, even on the higher frequencies, the max power output is about 6 to
7 watts....

Thanks
