6KD6=EL519 (near enough)For several years I used a bone stock Midland 13-898B which was a 23 channel SSB radio. Imade hundreds of DX contacts with it running strictly stock power and a 5/8 groundplane. Then later came the Wilson Shooting Star and stock power. Eventually I got a 40 channel SSB radio and added extra frequencies and built a little amp using a 6KD6 tube and it was like shooting fish in a barrel and things got even easier. I just laugh at people that think they need big power to work DX. My barefoot radios made contacts all over Europe, North and South America as well as into Africa and 100 watts into Australia and New Zealand all on 11m.
