Though we've advertised hundred-dollar converters, our biggest seller is our HJC-50. This little nuvistor converter is unbeatable for all but the most exacting applications. The circuit is simple . . , so simple you wouldn't expect that it took weeks and weeks of exhausting diddling before we had every aspect of it opti-mumized. The idea is to have just the right amount of gain so you can driva your receiver well, but not enough to run into overload problems. The grounded-grid 6CW4 provides an...

This is a common occurence these days, even with expensive manufactured equipment. One will just have to choose the portion of these wide bands that most appeal to his needs and furnish crystals to cover these segments. Since most side-banders 011 50 mc still seem to favor low end operation, it will probably be the most desirable to cover the first 500 kc of the 6 meter band, at least for a start. This being the case then, a crystal of 29 mc for the injection string will be used. This...
