[Elecraft] Fw: KPXA100 amp for KX-3

[Edward R. Cole]

For those who do not want to wait for the KXPA100, I will "soon" 
offer a 140w amplifier that drives with 5w (runs on 13.8vdc) with 
5.5w x 11.5d x 4.5h package - weight unknown but probably 10-12lbs.

This will have a 6-band LP filter with optional auto-band select for 
radios like the K3 or K2.  I am still working on the custom LP filter 
pcb layout.  The current version uses relay TR so is not QSK.  I may 
try to make a diode switched TR that can support QSK in the future.

This amplifier is offered as a bare "kit" by Communications Concepts, 
Inc. (AN762) and can be seen on my "kits made by KL7UW" webpage (link 
below).  It is identical in layout to my 300w amp (28vdc) I am 
currently running with my K3/10 at 270w.
