Feedback - May, 2003 QST

  • Yes, you're seeing double and no, it wasn't an April Fool's joke. If you look closely at the photo of the Rock-Mite transceiver ["The RockMite--A Simple Transceiver for 40 or 20 Meters," pp 35-38] on the cover of the April 2003 issue of QST, you'll see that the board contains two 12C508A PIC microcontrollers. It should have only one, of course. The other IC should be an LM1458N and it's the one closest to the board center. Thanks to Geert Jan, PE1HZG, for pointing this out. While we're at it, in the text on page 37, diode D6 was called out as the final amplifier clamp diode. It should have been D8.

  • A diligent reader pointed out a reversal of roles in the article "The ARRL Field Organization: Something for Everyone" [Mar 2003, pp 50-54]. The first paragraph of the second column on page 51 should read "The SEC oversees a number of DECs," not the other way around.
