A modulator of simple design that can beadapted readily to use with this transmitterwas shown in QST for December, 1954, page 6L6 can be substituted for the 6V6GT shownin the original, if more audio power is required. Power output at 300 volts is about 10 watts,which is enough to do interesting work on 220Mc. if a good antenna system is used. Antennaideas can be found in December, 1953, QST,or in any recent edition of either The RadioAmateurs Handbook, or the ARRL AntennaBook. The transmitter may also be used as asource of driving power for any of the largerdual tetrodes, such as the 6524, 6252, 5894 or9903. The first two will take up to 50 wattsinput on 220 Mc, the latter two up to 100watts or more. 126 rminal Radio for a CAREER I
