[Elecraft] K3s pre-purchase question

Based on your current operation and your present listing of equipment, 
I'd suggest the K3S-100.  You have a tuner so no internal ATU unless you 
want the internal automatic convenience.   You have a good mike, I use 
one of those myself.  As to filters, the standard filter is most 
adequate and always and one can add additional filters if desired.  If 
you intend to operate CW perhaps a 500 Hz or 400 Hz filter would be a 
nice initial choice.

As to the 10 watt vs. 100 watt radio, if you wish to operate lower power 
then the 100 watt will easily back down to 10 watts or less. However, 
with the somewhat compromise attic antenna, a bit more power is likely 
preferred.  Thus I'd opt for the 100 watt version.

As to 2 meter operation, unless you intend to work SSB, I'd opt for a 
dedicated VHF/UHF FM radio for repeaters and FM simplex.

So in summary, K3S-100 either F or K being factory assembled and tested 
or the kit.
