Chats With the Editor SCANNING the pages of this issue our readers will find a wealth of construction material— from the simplest to the most complex receiver. One feature this month deserves special mention. On page 18 we are printing full constructional data on the superheterodyne originally described in the November issue. Flooded with requests from all parts of the country, and from abroad, it became almost imperative that further data be given to at least attempt to stem the tide of correspondence which this set evoked. So we trust we have done our duty well and that all our correspondents will find an answer to their every question. Next month, due to the craving of the average home constructor for a beautiful thirty-six inch cone speaker, we are going to publish complete details that will enable any reader to make such a cone and get real enjoyment from the task, which, by the way, is not so difficult as it might seem. Fans who have followed the description of the Henry-Lyford receiver will find another article by Mr. Lyf ord in this issue which will increase their stock of knowledge on that subject. For the beginner in our next issue we will have a new article from the pen of Armstrong Perry showing a few of the possibilities of regeneration, while the seasoned builder will find described a well-known receiver with power amplifier installed in the same cabinet. Be sure to read Robert J. Casey's humorous story of the vicissitudes of broadcasting — it will be found on page 11 of this number. Editor of RADIO AGE.
