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. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
