[Elecraft] K3 as WSPR transmitter

[HP]

I see the lore is that the LPA does not care for long key down periods - 
I was toying with using my K3 as WSPR tx on 160 and 80 fpor some antenna 
evaluations. . 

The lore would say its not a good idea ? 

The manual is not clear to me of whether in fact there is a 160 low level out I 
could use for a home brew external amp -The KIO3 transverter bands 
show 160 coded -but other tables talk about just IF of 7 mhz and above. 

BUT its all moot of the LPA is still biased on and limited in key down time ?????
