is anyone out there now using a external amp on their k1 or k2 rigs? I see a number of cb type amps listed for sale that are susposed to cover 80-10 meters at various power levels, but I am sure they are not giving the cleanest sig on the bands. how about some ideas on this for the times where 5 -10 watts won,t cut it and 40 or 50 would? ken w8ob
