All in all a very good little radio for simplex work, but rather deaf
compared to say a Motorrola MC80.
To increase duty cycle i took apart the final stage and placed the
transitor into a larger cooling plate, the freq, stability increased
dramaticly and of course full duplex became possable.
I belive the KS900 has been succeded by the KS100 which is said to be 5
watts out, as to its specs i have no idea, i would be very interested,
