[Elecraft] Problems on 40M with 100 watt section

[Ron D'Eau Claire]

You should see 100 watts on ALL bands so, yes, those are down. Are you
making a minimum of 10 watts out on all bands with the KPA100 disabled? 

I don't have a KAT100 myself, so I won't speculate on what might have caused
your original issue beyond the obvious observation that, apparently, it
wasn't really out of the circuit in some way. It may not have been tuning,
but clearly there wasn't a 50-ohm non-reactive path through it either.

Ron,

This was into a dummy load.

I had it into the KAT100 which was disabled and unplugged. So only the 
feedline was left connected though the ATU. Once I removed the KAT100 it 
worked.

With the AT removed I did check power output into a dummy load and got the 
following

160- 131 watts
75- 118 watts
40- 119 watts
20- 54 watts
17- 55 watts
15 -98 watts
12 - 78 watts
10- 99 watts.

So 20 and 17 are down and 12 slightly??

So I am thinking it must be ATU related and not the 100watt amp section.

Thanks

Rich
