[Elecraft] KPA 100 use as standalone PA; emulation of K2 with an interface; analyzation of aux bus protocol

[Don Wilhelm]

Paul,

I did not see a response to your question, but I believe the answer is NO.

I would suggest that would be a difficult task.  Could the KPA100 be 
converted to a standalone amplifier, I think the answer is YES, but it 
would require a substantial amount of work.  The bandswitching *could* 
be accomplished by a multiposition manual switch or an add-on frequency 
sensing device, and if the driving transceiver can communicate the 
Transmit or Receive status, you *could* make the T/R switch function 
properly.  Other functions depend on the K2 firmware functions, such as 
the PA temperature which would in turn control the fan speed.

All in all, I do not think the benefit derived would be worth the cost 
and effort.  If one has a KPA100 that could be used for the "butchering" 
job, that is one thing, but if contemplating buying a KPA100 kit and 
building it as a standalone amplifier seems to be more expensive than 
purchasing one of the amplifiers in the 100 watt (or greater) class.

73,
