    possibly a poor choice of words, maybe a better wording would have been 
overly optimistic...
 It just seems that long after something is general knowledge, the status 
still reflects something different...

such as K-TX,  more than one person has reported that it looks as the 
transmitter has partially failed, signals have dropped... not being on K I 
can not personally confirm this... but the website shows K as being 
operational,so is that status correct?

L2 receive shows operational, but there is a 6db drop on its sensitivity over 
L1,shouldn't it be marked partially failed? I still hope that the 6db drop 
disappears... which it has done a couple times...be nice if it stayed gone...

    The rumor has it that the X-TX has no power to the TWT,but the website 
has it as needing more testing, so is the rumor false and we can look forward 
to the mode X downlink? I sure hope so !!! I was looking forward to that 

Is there anyone that could give a brief health check status on ao-40? and 
maybe do a little peek into the future for ao40 long term health?

  I had concerns that because of the explosion that fuel may have been sprayed 
over the insides, since it is corrosive is there a concern for a shortened 
life span for ao40?
