[Elecraft] Upgrading K2 #2117 to 100w

[Curt Milton]

I confess I have not been inside my K2 since I installed the SSB board, not too long after I built it.  I still need to perform the mod on the static-ky audio (mine isnt that bad but I think its time).  

Now I am contemplating upgrading to 100 watts, once I figure out how many upgrades I need to make.  I downloaded the Upgrading to Rev B instructions, and the KPA100 instructions.  And I am trying to digest all this!  

My current firmware is 2.01F.  

Now what purchases must I make (in addition to KPA100) to enjoy this rig at 100w?  

I am sensing with the additional thermal load that perhaps the PLL and BFO upgrades are prudent.  OK another $29 here does not sound too scary.  My QRP K2 has nice frequency accuracy thru 20m, but on 10 and 15m i have noticed a small error which puzzled me until I read about the PLL upgrade.  

I am not contemplating adding DSP or an autotuner - so is my firmware good enough ?  

Is there anything else that I must upgrade to enjoy this rig at 100 w ?  

I understand it is prudent to evaluate all the aspects in the revision B instructions while the rig is receiving other mods, but I havent noticed any of these issues yet.  

Looking for enlightenment on how to upgrade this middle-aged K2.  

73, curt
