[Elecraft] Considering a KPA-500

I used to run an ACOM 2000A and now use the KPA500 almost exclusively. On  
CW I notice no issues.  There have been a couple of times on SSB when I  
wished I had the 1500W but I eventually got thru.  I'm working on DXCC for  
160m and wonder if this will be an issue but so far if I can hear them I can  
work them (RX is only my inverted L).  We'll see when I put up my short  
vertical array this summer (Hi-Z). This is only anecdotal evidence and may not  
have really been an issue.  The K3, KPA500, KAT500 is essentially a 500w  
transceiver and works flawlessly for me.

Hi  all,

I am considering a KPA-500...  I currently have an AL-82, and  am getting
tired of all the band switching etc.

My only real issue  with the KPA-500 is the output power of only 500
watts.  Just how much  of a hit will I take by going from 1500 watts to
500 watts...  I chase  DX, via RTTY and CW mostly, and some SSB.  

I get DB, and realize  that I will take a roughly a 5 db loss in signal,
which is one S-unit...  

Will the KPA-500 take key down for 10 or more minutes at full  power??

Is there anyone on here that has gone from 1500 to 500 watts,  and if so,
can you tell me a bit about it?  How does the LPA-500  operate on MARS
frequencies?  They are all over the place, not in ham  bands...
