Feedback - December, 2002 QST

Author Jack MacLean, K2IUK, points out that the word "hardly" was erroneously omitted from the first sentence of the second paragraph in his "Vocoder Revived" piece [Technical Correspondence, Oct 2002, p 69]. The sentence should have read "Certainly, the achievements of today, as described in the update article, could hardly have been envisioned about 70 years ago when Homer Dudley at Bell Labs described his design of a voice coder, the Channel Vocoder."
The center frequency in the drawing in "How's DX?" [Oct 2002, p 77] should read 21,447 kHz.
