Feedback - June, 2003 QST

In "The Load Shedder," Feb 2003 QST, page 62, Figure 2, pins 6 and 7 were reversed for U1A, along with their plus and minus symbols.
Clarification: In "New Products," May 2003 QST, page 58, the $19.95 price applies to the recently introduced Radio Warehouse index dividers for WAS. The DXCC index divider set costs $49.95 plus shipping.
There is a discrepancy in the published results for third-order intercept points in the Product Review of the IC-746PRO [May 2002 QST, pages 74-75]. MDS method measurements were published for seven of the eight band-spacing combinations. The ARRL standard method uses an S5 reference. Correct third-order intercept figures using the S5 method are in the table.
