[Elecraft] I changed K2 R98 to 1K - not good?

[Don]

I'll bet you find out that the 1 K you put in was actually some other value 
.. or .. something happened you did not plan (cold solder joint?).  If the 
value of 1K is too high for your particular K2/100 the output will not reach 
full ratings on some bands but it will still be a lot higher than 0 or 1 !

Yep, use a pot or just patch in various fixed resistors like I did.  I also 
tested the value of the fixed resistor I was inserting just to make sure it 
was what I thought it was.

My K2/100 shows a lot of variation in TX output, esp. on 40 meters.  I'll 
set it for 50 watts and the power will toggle up and down by 10's of watts. 
Time to change R98.

Checking old posts, I see that values of 1.1 KOhm seem to be good,  I have a 
1K resistor so I put that in.  Put the rig back together and ...

Max output on 40 meters is about 3 watts.  It is lower below and above 40 
and on 20 or above there is no output.  Hmmm, did I do bad?

My next step will be to parallel another R with R98 so I can drop the 
resistance and see if I regain some power.

Sheesh, and this is on the eve of SKN too.  What a bad time for my rig to be 
down.
